HUMMINGBIRDS (TROCHILIDAE)

Transcription

1 HUMMINGBIRDS (TROCHILIDAE) DRAFT 1/7/08 Green Violet-ear Colibri thalassinus STATUS AND HABITAT: Casual summer visitor. Two records, both from Southern Interior in residential gardens with hummingbird feeders and exotic flowers. SEASONAL PATTERNS: Although unexpectedly scarce in Louisiana given the number of extralimital records elsewhere in the eastern USA, the seasonal pattern is the same, namely late spring through early fall. This pattern differs from that shown by other western and Mexican hummingbirds in Louisiana. One possible explanation for the species relative rarity in Louisiana is that this species is a bird of mountainous regions, and so the flat topography of our state must appear highly unsuitable to a wandering Green Violet-ear. RECORDS: 30 June 7 Aug. 1999, Lafayette (J. Oelkers, G. & J. Andriano, BF, WDP, PEC, DLD, SWC; ABF, Purrington 1999, Dittmann and Cardiff 2003, including photo by WDP) 9-10 May 2004, <loc> (C. Vildibill, WDP, PEC; Wallace 2004; photo by WDP published North American Birds 58: 461) IDENTIFICATION TIPS AND BEHAVIOR: The harsh, ticking call notes and song of this species should give away its presence. SOFT PARTS: Iris dark, bill black and tarsi and toes blackish. DIET: The Louisiana birds were drinking from hummingbird feeders but also presumably taking small insects, as is typical of all species of hummingbirds. SUBSPECIES: Photos of the individuals in Louisiana indicate that these individuals are almost certainly of the Mexican (nominate) subspecies. UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Broad-billed Hummingbird Cynanthus latirostris STATUS AND HABITAT: Rare winter resident. 34+ records, mostly from Coastal Zone; 8+ records from Southern Interior. All records <but one?> are from residential gardens with hummingbird feeders and exotic flowers. This species seems to be in the process of colonizing Louisiana as a winter resident; it is showing a pattern followed previously by several species, particularly Buff-bellied. The first record was found only in 1990, and the number of records is clearly increasing (Fig. ##).

2 Fig. ##. Historical trend in number of records of Broad-billed Hummingbirds in Louisiana through winter As with Buff-bellied, the first records came from the Coastal Zone, followed in later years with multiple records in the Southern Interior, including a record from its northern edge in Rapides. See also general discussion under Wintering Western Hummingbirds in Introduction. Since winter , Thomas A. Sylvest began compiling individual records of this and other rare hummingbird species through the HUMNET list, and these compilations are archived at the Louisiana Ornithological Society website; those data are referenced as TSDB below. SEASONAL PATTERNS: Records extend from 29 Sep.<?> to 11 Mar., but the records are strongly concentrated in Nov., Dec., and Jan., with perhaps proportionally fewer records in February than most wintering hummingbirds <analyze TSDB>. Geographically, records also seem to be concentrated disproportionately in the east-central Coastal Zone, from Lafourche to St. Mary, relative to other wintering hummingbird species. <analyze TSDB> This is yet another western species that typically departs from its breeding range in the USA by early fall (Powers and Wethington 1999 BNA), months before birds begin to appear in Louisiana (see Intro).

Clifton; ABF, Cardiff 2007) IDENTIFICATION TIPS AND BEHAVIOR: This species call notes differ from those of any other hummingbird species in resembling the low chips of a Ruby-crowned Kinglet. BAND RECOVERIES: Of interest is that none of the ## individuals banded in Louisiana have been recaptured here in subsequent winters. However, <amazing Colorado details>. DIET: Louisiana birds have been noted feeding at hummingbird feeders and the flowers typically used by hummingbirds; they presumably also fed extensively on small insects. SOFT PARTS: Iris dark; bill reddish basally and blackish distally; tarsi and does blackish. SUBSPECIES: The subspecies that breeds in the southwestern USA is C. l. magicus. Whether this is the subspecies that occurs in Louisiana or whether it is the geographically closer nominate subspecies, C. l. latirostris, of northeastern Mexico remains to be determined because no specimens have been obtained. UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Buff-bellied Hummingbird Amazilia yucatanensis STATUS AND HABITAT: Rare winter resident (most winters) in Coastal Zone and southern half of Southern Interior. More common in Coastal Zone than Southern Interior, with almost all records south of about One fall record from southern edge of Northern Interior, and one spring record from northern edge of Southern Interior. Two summer records from Southern Interior. Found primarily in residential gardens with dense ornamental cover and hummingbird feeders, but also locally away from feeders along coast where flowers available in winter, particularly Turk s cap (Malvaviscus penduliflorus), e.g., Oak Grove in Cameron, Peveto Beach Woods near Johnsons Bayou, and Grand Isle. This species was not recorded in Louisiana until 1965 and not again until 1973, but then increased dramatically in late 1980's (Fig. ##). In the Coastal Zone, there were only eight records prior to 1980, but subsequently, there were multiple records most years, and by 1986, it became difficult to keep track of individual

4 records. For example, there were 30+ in , with as many as 5 during the winter at a single spot (NLN; Muth 1988). By 1990, the species was an expected wintering species in the Coastal Zone in small numbers at many localities. The first record for the Southern Interior was not until 1985, and that individual died in a hard freeze. Then, there were only four records until fall 1989, when records obviously increased. Starting about 1992, the species has become increasingly common, with as many as 12 recorded on the Baton Rouge CBC on 2 Jan (Binford and Demcheck 2005), and 4 individuals in one yard during a single winter (JVR). See also general discussion under Wintering Western Hummingbirds in Introduction. Fig. ##. Historical trend in number of individual Buff-bellied Hummingbirds recorded on Louisiana Christmas Bird Counts, to (data from National Audubon Society). The red line is a 3-year moving average. SEASONAL PATTERNS: The main pulse of wintering birds typically arrives in Louisiana in November. Some banded individuals that successfully wintered may return much earlier; although the sample size is small, these individuals have tended to return earlier each successive year. In spring, most wintering individuals leave by mid- March, and records of individuals present for only a few days in mid and late March were likely spring transients.

Its harsh, spitting rattle (recalling a Brown Thrasher alarm call) is unlike that of any other species recorded in Louisiana, as are many of the other vocalizations in its complex repertoire, especially a high-pitched whistled note. It easily dominates behaviorally the other hummingbird species that regularly occur in Louisiana.

6 DIET: In Louisiana, primarily sugar-water at hummingbird feeders but also a variety of flowering plants (see Landscaping for Birds section); as with other hummingbirds, presumably also a strong arthropod component. BAND RECOVERIES: Foreign recaptures: (1) HY-male banded (JBO) 17 Sep Rasin, <> Co., Texas, recaptured (WDP, R. & J. Must) 6 Nov Lafayette; then, it relocated to another site in Lafayette 3 miles away, where last observed on 20 Mar. 2003; subsequently recaptured (JBO) 6 Apr Rasin, where recaptured several times through 20 Sep (JBO); then recaptured (WDP) 3 Nov. 2003, Lafayette, and last seen there on 28 Feb. 2004; then recaptured (JBO) 11 March 2004, Raisin; (2) AHY-m banded (JBO) 19 May 2002, Raisin, recaptured (NLN) 14 Feb Returns: See entries under early fall records above. HIGH COUNTS: 6, 4 Dec. 1993, Reserve - La Place area (RJS et al.). SOFT PARTS: SUBSPECIES: Louisiana specimens are relatively pale below and bronzy above, and are indistinguishable from specimens of A. l. chalconota, the subspecies that breeds from southern south to northern Veracruz and San Luis Potosí, Mexico. UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Sibley (2000) portrayed this species as only casual in southern Louisiana (and the western Gulf Coast); for an accurate map, see Williamson (2001). Blue-throated Hummingbird Lampornis clemenciae STATUS AND HABITAT: Two records, one from late fall in Southern Interior and one from late winter in Coastal Zone, both from suburban yards. RECORDS: (f) Nov. 1992, Baton Rouge (MMS, SWC, DLD, JVR, AWK, MLD, AES, GBS, JPS, al.; ABF, Jackson 1993, Dittmann et al. 1998; photos deposited in LOS BRC file) (f) 7 Mar Apr. 1995, Slidell, St. Tammany (P. Siegert, NLN, JPS, PAW, SWC, M. Griffith, JPK et al.; ABF, Muth 1995, Dittmann et al. 1998; banded by NLN; photos deposited in LOS BRC file) IDENTIFICATION TIPS AND BEHAVIOR: The high-pitched, frequently given "seet!?" note is characteristic of this species. DIET: The Baton Rouge bird fed at rosy-flowered "sassanqua" camellias, Abutilon pictum, and a hummingbird feeder. SOFT PARTS: Iris dark, bill black, tarsi and toes blackish. SUBSPECIES: The absence of specimens prevents assigning the Louisiana records to subspecies. All three described subspecies could potentially occur in Louisiana. One (L. c. bessophilus) breeds in Arizona and New Mexico (and nw. Mexico), another (L. c. phasmorus) breeds in the Chisos Mountains of Texas (and n.-central Mexico), and a third (nominate clemenciae) is restricted to Mexico but occurs as far northeast as Nuevo León and may occur closer to Louisiana in terms of direct distance than the other two subspecies; see Williamson (2000) for details. UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Magnificent Hummingbird Eugenes fulgens STATUS AND HABITAT: One record, from late fall in extreme eastern Coastal Zone. RECORDS: (imm/ m) Nov. 2004, Slidell, St. Tammany (K. T. Porter, LJB, B. Wayman, J. Turner, WDP; ABF with photo by J. Turner, Duncan & Duncan 2005) IDENTIFICATION TIPS AND BEHAVIOR:. DIET: The Louisiana bird fed from hummingbird feeders and flowers, and was also seen sallying for flying insects (LJB). SUBSPECIES: Although no specimen is available, Louisiana records would almost certainly pertain to the northern, nominate subspecies. UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Ruby-throated Hummingbird Archilochus colubris STATUS AND HABITAT: Common breeding species in Northern Interior and Southern Interior, and fairly common to uncommon in Coastal Zone; breeding not recorded in coastal woodlands or most of coastal marsh region. Formerly rare in early winter casual in late winter in Coastal Zone and casual in early winter in Southern Interior, but since winter (e.g., Stedman 1999) becoming more common and now occurs annually in small numbers through the winter in all suburban areas in Coastal Zone and in the southern half of the Southern Interior. Casual in late winter in N. Interior; four have successfully over-wintered since Breeds primarily in deciduous forest and woodlots, ranging into suburbs for foraging. More widespread during migration, even occurring in open fields with suitable flowers.

7 The Breeding Bird Survey trend for Louisiana for is negative (-3.2%/year), but falls slightly short (p <.07) of conventional levels of statistical significance, due perhaps to low rates of detection by BBS methods. Winter records, however, have increased dramatically. In the Coastal Zone, there were only four convincing records from winter before 1988, followed by near-annual reports in the 1990s. By winter , at least two feeders in the Coastal Zone had multiple individuals overwintering (RJS, DPM; ABF). By winter , records became so numerous that many observers stopped reporting them individually. In the Southern Interior, the first early winter record was not obtained until 1989; records then increased through the 1990s, with a meteoric rise starting also in winter , when, for example, JVR had at least six different individuals at his feeders near St. Gabriel, Iberville, including 4 banded on a single day, 27 Jan., by WDP. By the following winter, records were too numerous to tally. Before about 1995, Ruby-throated was far less likely to be seen in winter than not only Rufous or Black-chinned, but also Buff-bellied, Calliope, or Broad-tailed hummingbirds. For example, on the Baton Rouge CBC (Fig. ##), the first record was 1991 and few were recorded until the late 1990s, but by winter , 18 were recorded on the Baton Rouge CBC. Fig. ##. Historical trend for number of Ruby-throated Hummingbirds recorded on the Baton Rouge CBC, to (data from National Audubon Society). The red line is a 3-year moving average. The statewide trend is also similar (Fig. ##).

8 Fig. ##. Historical trend for number of Ruby-throated Hummingbird records on Louisiana Christmas Bird Counts, to (data from National Audubon Society). The red line represents a 3-year moving average. In winter ) 16 individuals were banded (LJB) from Dec. to early Mar., including two returnees from previous winter. In winter , 16 individuals were banded from Dec. to Feb. in s. St. Tammany, including a female from the previous winter (LJB; ABF). The increase is not an artifact of increased observer effort: sites with constant effort also registered the increase. The increase also follows the precedent of historical increase set by Buffbellied, Calliope, and Broad-tailed Hummingbird (and probably also Rufous and Black-chinned). See also general discussion under Wintering Western Hummingbirds in Introduction. Kopman (1915) stated that he had two reports of this species in winter, but we suspect the species identification was based on the assumption that Ruby-throated was the only species that could occur in Louisiana. Starting in the mid-1970s, we learned that Ruby-throated was one of the least likely species to occur in winter, thanks largely to the intensive efforts of the pioneers, especially Nancy Newfield, in studying winter hummingbirds. There were 23 reports (ABF) prior to 1975 of female or sex-unspecified Ruby-throated Hummingbirds (no adult males) from mid-november to late February. Although these almost certainly pertained to small North American hummingbirds, we are reasonably certain that Black-chinned and other species of western hummingbirds were not considered in the identifications SEASONAL PATTERNS: In spring, the first adult males typically appear in the Coastal Zone and Southern Interior about 5-10 Mar., with records extending to 1 Mar. The first females typically appear in late March. Arrival in the Northern Interior is usually 1-2 weeks later. Despite the early arrival, the species does not become common until mid or late April. At Remsen s study site in Iberville (Fig. #), censuses show a steady increase from mid-march through April, leveling off in May and June, followed by a peak from July through mid August, followed by a decline to early September, then an increase through late September, followed by a decline through October; most individuals have departed by the last week in October. Kopman long ago (1915) reported that there was a major spring influx 5-15 May. Migrants are detected in nonbreeding areas along the coast steadily into the third week of May, with records extending to 2 June.

9 J F M A M J J A S O N D Fig. ##. Seasonal pattern of occurrence of Ruby-throated Hummingbird at Remsen s study site in Iberville, (N = 1178 censuses); the red line is a 5-day moving average. The onset of fall migration is difficult to discern, but birds are detected away from breeding areas, e.g., New Orleans, starting in June. At Remsen s wooded study site near St. Gabriel (Fig. ##), an influx of birds to feeders begins in July; whether these are local post-breeding dispersers or fall migrants from farther north is not known. Peak counts are from mid-july into the third week of August, followed by a major exodus in late August. A second peak then occurs in late September and early October, followed by a major exodus in the second week of October, with a few individuals lingering until the first week of November. In suburban areas, a major influx occurs in late August and early September, as also noted long ago by Kopman (1915). A substantial movement westward along the coast of Cameron was detected on 31 Aug. (1990), when 52 were counted flying across Calcasieu Pass in 15 mins (JMB et al; ABF) SIGNIFICANT RECORDS: early spring Coastal Zone: (ad. m) 27 Feb. 2005, Slidell, St. Tammany (P.

Barrow, D. Rivet; photo in ABF). Several additional all-white individuals have been discovered over the last 10 years. IDENTIFICATION TIPS AND BEHAVIOR: See Dittmann & Cardiff (<REF>). As early as 1986, Louisiana observers have been using the absence or presence of tail pumping while feeding as a criterion for separation of Rubythroated from Black-chinned. Ruby-throateds pump their tails while maneuvering to a feeder or flower, but once the bill is inserted into the food source, they do not pump their tails, in contrast to Black-chinneds, which typically pump their tails constantly, at a rate of several per second. The authors have observed many thousands of feeding Rubythroateds in Louisiana from May through September, when Black-chinned is not known to be present, and have never seen one pump its tail while drinking other than an occasional nervous jerk. In contrast, every Black-chinned that they have seen in Louisiana (adult males or identified by primary shape or combination of long bill, grayish crown, and dull, not bronzy, green back) has pumped its tail vigorously while feeding. Peak activity around feeders occurs just before and, especially, just after rain; for example, on 21 July 1991 after a thunderstorm, JVR (ABF) counted 317 individual visits, involving an unknown number of individuals, to his hummingbird feeder in only 15 minutes. Reasons for this are not known for certain but may involve the immediate need for calories after a rainstorm prevents them from feeding, particularly if the birds themselves get wet. However, PMD has found nectar to be severely diluted in flowers of various species of Salvia following rain, e.g., sugar content dropped from 28% to 6% when rain-drops were present on flowers. Therefore, the primary reason for the spike in feeder use after rains is likely dilution of natural nectar sources by the rain itself. DIET: In addition to flower nectar, feeds heavily on insects, typically gleaned from foliage and small twigs while hovering. The spring arrival of Ruby-throated Hummingbirds in the Baton Rouge area coincides with peak flowering of copper iris (Iris fulva), an iris with a floral morphology clearly modified for hummingbird pollination, and it seems likely that this hummingbird is the primary pollinator of this plant species (although this is evidently not documented in the technical literature as summarized by Robinson et al BNA. Another potential food plant, crossvine (Bignonia capreolata), has a similar phenology, but we have few observations of its use by Ruby-throated Hummingbird. In the Northern Interior, blooming red buckeye (Aesculus pavia) is abundant in upland areas and coincides neatly with the spring migrant period as the primary native nectar source. First blooms for red buckeye in Bienville and Caddo and Iris fulva in Tensas occur around the normal first arrivals for males. Coral honeysuckle (Lonicera sempervirens) is a

12 highly favored nectar source available throughout the spring but is uncommon in the wild in most areas of Louisiana. Later in spring, introduced Japanese honeysuckle (L. japonica) becomes a primary food plant. From late spring through early fall, trumpet-creeper (Campsis radicans) is the most important nectar source. The flowering of cardinal flower (Lobelia cardinalis) and horsemint (Monarda punctata), mainly late August to early October, appears timed to coincide with the influx of fall migrants. Likewise, the late summer-early fall flowering of scarlet morning-glory (Ipomoea coccinea) in the "river parishes" of the Coastal Zone coincides with the late summer-fall dispersal of this hummingbird. Numerous exotic plants, especially Salvia spp., Cuphea spp., and Abutilon spp., provide additional nectar sources (see Landscaping for Birds section). Sugar concentrations in nectar of all native flowers used in Louisiana is normally 28%-35% (PMD) or 21%-35% (D. Demcheck). Fontenot (1998) observed one probing holes made by other birds in fruit of common persimmon, presumably to obtain juice.

Winter returns: A female banded in winter in St. Tammany was recaptured there annually through winter (LJB). A male, banded Dec 2000 as HY in Covington, St. Tammany, yard was recaptured Nov 2002 and Dec 2003 (LJB, H. Patten). A female banded at the Dittmann-Cardiff study site near St. Gabriel, Iberville, was first noted on 28 Dec and remained well into spring, 1 May 2004 (SWC, DLD, WDP; ABF). Breeding site philopatry has been documented by PMD in Caddo, where breeding individuals of both sexes banded in spring 2003 were recaptured at the same site annually through summer of 2007; 20% of adults captured there in spring 2007 had been banded there in previously years. HIGH COUNTS: Estimating numbers of hummingbirds visiting feeders during spring and fall is difficult. Dr. Peter E. Scott, an expert on hummingbird feeding ecology, provided the following calculations based on sugar consumption per day. A 3-4 g Ruby-throated Hummingbird requires about 8 kcal of energy per day, which it can obtain from about 2 grams ( pounds) of sugar per day. Therefore, one can keep track of the number of pounds of sugar used over a time period and divide this weight by to provide a rough estimate of the number of hummingbirds using the feeder. Sugar water is also lost to spillage and bees, but this is undoubtedly more than compensated for by the fact that the hummingbirds undoubtedly have other sources of food, e.g., flowers, arthropods, and other feeders. Applying this method to JVR's feeders near St. Gabriel, where during peak visitation periods, about 1 pound of sugar is consumed per day, the minimum estimate of number of Ruby-throated Hummingbirds using his feeders daily is 227 individuals. If the birds obtain only half of their calories from JVR's feeders, then the estimate is more than 450 individuals. Yet seldom are more than individuals present simultaneously. The vast majority of these individuals seem to commute substantial distances to the feeders (and they frequently fly out of sight after leaving the feeders).

N of St. Gabriel, Iberville (WDP[banded], JVR; ABF) SOFT PARTS: UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Beware that Sibley (2000) portrayed this species as only casual in winter in southern Louisiana (and the Gulf Coast); for an accurate map, see Williamson (2001). Black-chinned Hummingbird Archilochus alexandri STATUS AND HABITAT: Rare winter resident in Coastal Zone and southern half of Southern Interior; casual in n. S. Interior and N. Interior, with remarkably few records north of about N. Lat. Found primarily in residential gardens with hummingbird feeders, especially where some tall trees present. Although this species was not officially recorded in Louisiana until 1955, sight records by GHL of birds identified as Ruby-throated at Monroe on 10 Dec and 8 Dec (Oberholser 1938) were, with the benefit of hindsight, much more likely to have been Black-chinneds by date. There were only 9 records of Black-chinneds through 1975, with individual records reported in Amer. Birds through at least winter Since the late 1970's, however, this species has been recorded every winter, sometimes with as many as 5 recorded in a single yard (NLN;

13 ABF). By 1984, multiple individuals were recorded annually in Reserve, St. John (RJS, MW; ABF). By winter , as many as 23 were banded in a single winter (NLN; Muth 1988), and tracking individual records became impossible after about CBC totals show a strong increase since about 1985 (Fig. ##). Assessing the historical trend in this species is much more problematic than that for other hummingbird species because of difficulties in distinguishing it in the field from Ruby-throated Hummingbird. Females were considered inseparable in the field until the 1980s, and all records before 1985 were males unless hand-held or collected; the first female was not documented until Dec (NLN, ABF). Therefore, the surge in records in the late 1970s (Fig. ##) is certainly in part due to increasing observer awareness, triggered by the banding efforts of Nancy Newfield, that the species was more likely than Ruby-throated in winter. On the other hand, as with other species of western hummingbirds, there has almost certainly been a true increase in numbers of individuals. For example, the <get date> Baton Rouge CBC recorded 21 individuals, more than recorded in all of Louisiana prior to 1975 and more than recorded statewide in most years up until the late 1980s. Furthermore, numbers recorded on CBCs statewide has increased steadily since the late 1980s (Fig. ##). See general discussion under Wintering Western Hummingbirds in Introduction. Figure #. Historical trend in number of Black-chinned Hummingbird records in Louisiana through 1984.

14 Fig. ##. Historical trend for Black-chinned Hummingbird records on Louisiana Christmas Bird Counts through (data from National Audubon Society). The red line is a 3-year moving average. SEASONAL PATTERNS: The first birds of the winter usually arrive in the last week of October, and the peak of first detections is typically in November (TSDB). The earliest arrivals are typically adult males, several of which have been banded individuals returning to a previous wintering site. Individual wintering birds may leave anytime, but most are gone by early March, with few April records and only two records from May. More than any other wintering hummingbird species, many Black-chinneds seem to come and go through the winter. Fall arrival schedule undoubtedly made more difficult to ascertain by presence of Ruby-throateds through at least October; spring departure schedule also obscured by arrival of Ruby-throateds in early March. Breeding populations in the western United States begin migration in July and peak movement is in August, even in southern Texas (see Baltosser and Russell 2000); thus, this is one of several species of western hummingbirds whose main arrival in Louisiana is generally 1-2 months later than the peak of fall migration in the rest of the United States and long after most individuals have left the western United States.

SOFT PARTS: SUBSPECIES: Although no subspecies have been described, Baltosser and Russell (2000) noted that populations from s. Texas and Mexico are significantly smaller in size than those from the rest of the USA breeding range; therefore, small individuals found in Louisiana in winter may have originated in that part of the species range.

Anna's Hummingbird Calypte anna STATUS AND HABITAT: Casual in fall and winter in Coastal Zone (17 records) and Southern Interior (11 records). Unusually high proportion of records (compared to other western hummingbird species in Louisiana) are from southwestern Louisiana. The first three records were from scrubby coastal woodlands with many acacia thickets; subsequent records have been from residential gardens with hummingbird feeders and exotic flowers. In contrast to other winter-season hummingbirds in Louisiana, Anna s Hummingbird has not shown an historical increase since the first records (Fig. ##) despite greatly intensified coverage of wintering hummingbirds (and also despite a well-documented range expansion in the western United States; REFS). After the first three records, all in 1979, none was recorded until Records tend to come in bursts, such as winter and , and there may be no records for several years in a row. See also general discussion under Wintering Western Hummingbirds in Introduction.

17 Fig. Historical trend in the number of Anna s Hummingbird records in Louisiana. SEASONAL PATTERNS: Of the 28 individuals, 21 were first detected in November and December, a fairly typical pattern for wintering western hummingbirds. Most individuals depart by early February, likely earlier than most other western species and consistent with its winter breeding season in California. One anomalous first detection from early August. RECORDS: Coastal Zone: (f) 10 Nov. 1979, Hackberry Ridge, 2 mi.

Calliope Hummingbird Stellula calliope STATUS AND HABITAT: Rare in late fall and winter in Coastal Zone and southern half of Southern Interior. Two records from Northern Interior. All records are from residential gardens with hummingbird feeders, especially in rural areas, where favored habitat is dense weedy thickets. Until about 1995, a casual late fall and early winter visitor to Coastal Zone and Southern Interior. Subsequently, this species has undergone one of the most dramatic increases of any bird species in Louisiana, with many cases of 2 and 3 individuals appearing in the same garden simultaneously and some yards recording up to 5 individuals during a winter. Through the winter of , keeping track of records of Calliope Hummingbirds was fairly easy, and these are enumerated below, primarily for the historical record. Starting winter , tracking individual records became impossible, because most were not even recorded in the ABF. CBC totals show a strong historical increase starting in the mid 1990s (Fig. ##).

19 Fig. ##. Historical trend for Calliope Hummingbird records on Louisiana Christmas Bird Counts, to (data from National Audubon Society). The red line represents a 3-year moving average. To illustrate the historical change in status, LJB banded 15 individuals in , 14 in St. Tammany, and has banded 2 to 3 individuals during single sessions at three different St. Tammany sites. See also general discussion under Wintering Western Hummingbirds in Introduction. Until the first Louisiana winter records, this species was unknown anywhere in North America in winter, with few documented records for the western United States later than early October. SEASONAL PATTERNS: Other than individual records from late July, late September, and early October, all documented records extend from 23 October on; most individuals arrive in Louisiana in November and early December. However, apparently new individuals may arrive almost throughout the winter. Most individuals have left by mid-march, with the records extending into the third week of April. The main period of fall migration of the Calliope Hummingbird in the western USA is from mid-july to late August (<REFS>)<nothing in BNA!>. Therefore, the late fall - early winter pattern of occurrence in Louisiana, months later than in the western USA at similar latitudes, is intriguing; see Introduction for discussion, RECORDS: Coastal Zone through winter : (imm. m) 7-8 Dec 1982, Reserve, St. John (RJS, NJN, JVR, SWC[coll.]; Newfield 1984, LSUMZ ).

Wood, PMD[banded]; TSDB) (ad. m) 2-5 Sep. 2006, West Monroe, Ouachita (S. Pagans, J. Brown; ABF, including photo) IDENTIFICATION TIPS AND BEHAVIOR: The long wings typically appear oversized for its tiny body, and the bill looks disproportionately short; together these features, along with the dull plumage features, give the species a baby-like impression in the field. Typically tamer than other species. Often feeds close to the ground, and often within dense vegetation. Moves quickly and stealthily, often making it difficult to follow. Almost always at the bottom of the dominance hierarchy among our local species, and its strategy is to sneak into territories ruled by other species and visit feeders or flowers before detected by territory owner. Dittmann & Cardiff (REF). DIET: In Louisiana, primarily sugar-water at hummingbird feeders but also a variety of flowering plants (see Landscaping for Birds section). In addition to flower nectar, feeds heavily on insects, typically gleaned from foliage and small twigs while hovering but also by sallying into the air. JVR has seen one sallying for tiny flying insects when the air temperature was only 22 F. BAND RECOVERIES: Foreign Recaptures: HY-m banded (LJB, S.

SOFT PARTS: UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Several late summer/early fall records in the TSDB were not included because details never submitted. Beware that Sibley (2000) portrayed this species as only casual in winter in southern Louisiana (and the Gulf Coast); for an accurate map, see Williamson (2001). Broad-tailed Hummingbird Selasphorus platycercus STATUS AND HABITAT: Rare fall and winter resident in Coastal Zone and southern half of Southern Interior, casual in Northern Interior. All records are from residential gardens with hummingbird feeders. Until about 1995, a casual late fall and early winter visitor to Coastal Zone and Southern Interior. Subsequently, this species has increased sharply, with some cases of two individuals in the same garden simultaneously. Through the winter of , keeping track of records was fairly easy, and these are enumerated below, primarily for the historical record. Starting winter , tracking individual records became impossible, as with Calliope Hummingbird, because most were not even recorded in the ABF. Since winter , Thomas A. Sylvest began compiling individual records of this and other rare hummingbird species through the HUMNET list, and these compilations are archived at the Louisiana Ornithological Society website; here, we report summaries of those data (referenced as TSDB). The historical trend for this species on CBCs is strongly positive starting in the late 1980s (Fig. ##), although the trend isn t as smooth as for other western hummingbirds and the downturn seen in the last few years began before the Katrina-Rita effect. See also general discussion under Wintering Western Hummingbirds in Introduction.

24 DIET: In Louisiana, primarily sugar-water at hummingbird feeders but also a variety of flowering plants (see Landscaping for Birds section). In addition to flower nectar, feeds heavily on insects, typically gleaned from foliage, bark, and small twigs while hovering but also by sallying into the air. BAND RECOVERIES: Returns: f banded on 14 Nov returned to same yard in Lafayette for three winters (R. & J. Must, WDP [banded]; ABF). SOFT PARTS: UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: 29 Oct. 1989, New Orleans (see Dittmann 1995). Several late summer/early fall records were not included because details never submitted. Beware that Sibley (2000) portrayed this species as only casual in winter in southern Louisiana (and the Gulf Coast); for an accurate map, see Williamson (2001). Rufous Hummingbird Selasphorus rufus STATUS AND HABITAT: Rare fall migrant and rare to locally uncommon winter resident in Coastal Zone and southern Southern Interior (rare north of about N. Lat), rare in Northern Interior. By far the most likely species of hummingbird to be found in winter in Louisiana. Found primarily in residential gardens with hummingbird feeders or exotic flowers; rarely away from feeders and gardens in Coastal Zone in areas with substantial Turk s Cap (Malvaviscus penduliflorus), Japanese honeysuckle (Lonicera japonica), and other suitable naturalized flowers. This species has increased dramatically since the 1970s. See general discussion under Wintering Western Hummingbirds in Introduction. Because many records from the 1950s through the 1970s did not specify age or sex, nor considered Allen s Hummingbird as a possibility, we are unable to provide as accurate a tally of records as in most other wintering hummingbirds. Nonetheless, it is clear that this species has been present in small numbers in winter since at least the 1950s, with the first record even earlier (1934). That Rufous Hummingbird has become successfully established as a wintering species is illustrated by the numerous returns (likely 100+ when all data are available) of banded individuals in subsequent winters Fig. ##. Historical trend for Rufous Hummingbird records on Louisiana Christmas Bird Counts, through (data from National Audubon Society). The red line is a 3-year moving average. The numbers are very conservative because they do not include individuals reported as Rufous or Allen s, which usually outnumber those identified as certain Rufous (males with rufous feathers in back and banded females).

25 SEASONAL PATTERNS: Wintering individuals begin to arrive in early August, with a few records in late July, with an influx in late August and early September. Banding by NLN, WDP, and LJB has shown that most of the earliest individuals are adults returning to wintering sites from the previous year. Many of the non-returning early individuals stay only a few days. A dip in detection of new arrivals typically extends from mid September to late October, when a second influx begins, which peaks in November and early December (TSDB). However, new arrivals are detected throughout the winter, and banding studies show that although many individuals remain at wintering sites faithfully through the season, many others arrive and depart irregularly through the winter. The frequency of departures accelerates in February, presumably corresponding to departure for breeding grounds, and most individuals have left by Mar.; records extend into the third week of April. <BNA weak on western phenology get data elsewhere> SIGNIFICANT RECORDS: Coastal Zone before 1970: (m) 26 Oct. 1956, New Orleans (SAG; ABF) (m) 16 Mar. 1958, New Orleans (SAG; ABF) 29 Nov. 1958, 2 mi.

HIGH COUNTS: 8, <> Dec. 1992, Baton Rouge (NLN, MLD). <need to get single-day counts from NLN. LJB, WDP, LCB> SOFT PARTS: UNSUBSTANTIATED, DUBIOUS, OR ERRONEOUS RECORDS: Sibley (2000) portrayed this species as only rare/casual in winter in southern Louisiana (and the Gulf Coast); for an accurate map, see Williamson (2001). Allen's Hummingbird Selasphorus sasin STATUS AND HABITAT: Casual fall and winter resident in Coastal Zone and Southern Interior (which has substantially more records than Coastal Zone). One winter record for N. Interior. Actual status underestimated because female and most immature males are separable from Rufous Hummingbird only in the hand. All records listed below were of birds identified in the hand, with the exception of <> males identified by J-shaped display or by solid green back, without any rufous feathers, sharply demarcated from rump. Although green-backed Rufous hummingbirds have been documented (McKenzie and Robbins 1999), most still have a few rufous feathers in the back. See Dittmann and Cardiff (2003) for discussion. All records are from residential gardens with hummingbird feeders. Because of the difficulty in distinguishing this species from Rufous Hummingbird, any historical trends are highly influenced by the intensity of activity of Louisiana s hummingbird banders; until we can calibrate the record for degree if banding effort, no true trends can be identified. The increase in detections in recent years (Fig. ##) is most likely a consequence of increase banding efforts. Nonetheless, the remarkable number of records in winter almost certainly represents a true big year for the species. Perhaps it is not coincidental that until 2003, Allen s had no records of banded birds returning in subsequent winters, and records of adult males were very few. Therefore, until the last few years, this species seemed less likely than the others to be on a trajectory for colonizing Louisiana as a wintering species, but this is no longer the case.

28 Fig. ##. Number of Allen s Hummingbird records (N = 98) from Louisiana in 5-year intervals [re-calc]. SEASONAL PATTERNS: As with historical trends, our understanding of seasonal patterns of this species is made difficult by reliance on records of hand-held birds. For example, many Allen s Hummingbirds, unless recognizable as individuals, were likely present for unknown periods in advance of their capture and identification. With the caveat that any true seasonal trends would have to take into account the seasonal intensity of banding activity, a plot of the seasonal distribution shows that the pattern for this species is roughly similar to those of other western hummingbirds, with most records from November through March, but differing in a higher proportion of first detections in late winter. The latter is almost certainly a consequence of males molting into near adult plumage, creating increasing suspicion that an immature male Selasphorus is an Allen s. Records extend from 8 August to 4 April.
