2 EXECUTIVE SUMMARY One of the establishing purposes of the Alaska Maritime National Wildlife Refuge is to conserve marine bird populations, which requires the ability to detect large changes in abundance. Monitoring populations of auklets and other crevice-nesting seabirds has proven problematic even though numerous methods have been attempted since the mid 1960 s. Quantifying changes in geographical size of auklet colonies may be useful as an alternative to attempts to directly measure population size. Anecdotal evidence suggests several large colonies have decreased recently in both extent and abundance, simultaneous with vegetation encroachment and succession. We recently developed a new standardized method for colony mapping using a randomized systematic grid survey, which we employed in July 2005 on Hall and St. Matthew Islands. The survey had two components: a simple presence/absence survey and an auklet sign density survey. Quantitatively mapping all large auklet colonies using this method could provide an important, and logistically feasible, baseline for monitoring the status of auklet colonies through time. INTRODUCTION During late July 2005, we visited Hall and St. Matthew Islands in the Bering Sea Unit of the Alaska Maritime National Wildlife Refuge. As part of the Refuge s seabird monitoring program, we systematically surveyed three auklet colonies (one crew surveyed the main colony on Hall Island, while another crew on the north end of St. Matthew surveyed two colonies). To provide baseline data on geographic extent and relative density of auklets in the colonies, we mapped the colonies roughly following Renner and Renner (Renner, H. M and M. Renner Mapping distribution and relative density of least auklets at the Ulakaia Ridge colony, St. George Island, U.S. Fish & Wildlife Service unpublished report, AMNWR 04/05. Homer, Alaska.). Objectives for each team were to 1) complete presence/absence survey of one large colony using 50m grid cell width or 100m grid cell width (according to time available); 2) complete density surveys on systematic subset of plots including at least 20 plots (e.g., every 3 rd, 2 nd, up to 100% of plots depending on the size of the colony); 3) try to obtain subjective estimate of proportion of each species present by counting birds on several plots; and 4) opportunistically search for additional colonies and obtain coordinates describing their location. METHODS All surveys were conducted between 20 and 29 July 2005 (early chick rearing period) at the Hall and St. Matthew Islands. Weather in this period was normal for summer in the Bering Sea (fog and occasional drizzle but no major storms). During the survey period, some adults were carrying chick meals (HR, ILJ, personal observations, Alexander Kitaysky, pers. comm.) suggesting hatching had recently begun. Survey methods approximately followed Renner and Renner (ibid). Because we did not have a georeferenced map of the islands and we only knew approximate locations of the colonies, we generated a megagrid of square 1 km 2 cells that covered the entire islands. To simplify this we used a Universal Transverse Mercator map projection (UTM zone 2N, datum 2
3 WGS 84). Each 1 km 2 cell was uniquely numbered (Fig. 1) and corresponded to a pre-generated sampling grid available in both 50- and 100- m cell side lengths (to be selected in the field based on colony size and time available). At each scale, one circular survey plot of 16 m 2 was randomly placed within each grid cell. We used an R script (see Renner and Renner 2004) to generate UTM coordinates for survey points and randomize them within the grid cell (except points on St. Matthew were not randomized because of technical difficulties in the field). These waypoints (Appendix B) each served as the center of a survey plot. On Hall Island and the St. Matthew Glory of Russia colony we used grid cells 50m on each side, but at the St. Matthew Island Pterodactyl colony we used grid cells 100m on each side because this latter colony was more extensive. Coordinates of the survey points were uploaded to a handheld 12-channel WAASenabled GPS receiver (Garmin GPSmap 76s). By turning on the GPS s track log (i.e., record a position every 5 sec) while walking around the potential habitat it was possible to automatically discard some points as outside the colony without actually visiting them. The mapping effort consisted of two parts, a presence/absence survey and a density survey. As many points as possible were visited during the auklet activity period. The quantitative density survey was conducted on Hall Island only, where birds were recorded as present on the presence/absence survey at every second point; however, three points were skipped because a recent rockslide obliterated the area where these points fell. At St. Matthew, relative density was qualitatively assessed for every point by ILJ. All points were found with the GPS. Accuracy was usually <10m, often <5m, but only <100 m at some locations in the Glory of Russia colony at St. Matthew due to obstruction of the satellite signals by the >300 m high cliffs. For the presence/absence survey, direct and indirect evidence of nesting was used to detect presence (e.g., droppings, feathers, subsurface vocalizations, dander or regurgitated food) as well as birds standing on the surface or flying in or out of crevices. Surface birds were recorded on an opportunistic basis no determined effort was made to watch surface birds from a distance. The 2-dimensional colony area was calculated as the number of points with auklets present times the area of each grid cell (2500m 2 on Hall and m 2 on St. Matthew). We recognize that recording presence/absence within a small sampling plot, and then using this value to extrapolate to a much larger grid cell, results in downwards bias to our estimated colony area (e.g., some grid cells could have been classified as absent when somewhere else in the grid cell auklets were indeed nesting). The opposite extreme of this bias would have been to record whether auklets were nesting anywhere within the grid cell. We were interested in this question but found it impractical to rigorously sample at such a large scale as an entire grid cell. In order to learn more about the potential magnitude of this downwards bias, on Hall Island we also recorded whether nesting auklets were likely present anywhere within a 25-m radius (half the width of a grid cell). This provides a crude indicator of homogeneity of the colony. For the density survey on Hall Island, we subdivided each 16m 2 plot into eight equalsized subplots of 2m 2 to characterize variability at a smaller spatial scale. Droppings and feathers were counted on each subplot, and percent vegetation cover and its composition were estimated to the nearest 10%. In order to estimate relative proportions of least and crested auklets within the Hall Island colony, we conducted counts of birds attending the surface on 26 July. Observers sat at two 3
4 different locations near the center of the colony and recorded counts (within defined boundaries) of each species every 10 minutes from We conducted opportunistic surveys for additional auklet colonies on Hall Island throughout the entire visit. In addition, Dr. Alexander Kitaysky and Mike Schultz (University of Alaska Fairbanks) provided phenology information based on capture attempts for adults and direct observation of crevices incidental to their research. 4

6 RESULTS Hall Island Colony Description.--The main auklet colony on Hall Island is located on the west coast, approximately 2 km from the southern-most tip of the island (Fig. 2). The colony site consists of an actively-eroding scree and boulder slope dropping from a 200-m cliff to almost sea level (Figs. 3 and 4). The colony site is about 1 km long north to south and 400 m wide west to east, and is largely unvegetated, apparently due to frequent rockslides. A flatter bench in the middle consists of larger boulders and has more vegetation. There is only one safe access point to the colony site for observers (other than the beach if reached by skiff), and in 2005 this area was very actively slumping. During our study period, two UAF researchers had a frightening experience in the center of the colony when a rock the size of two school buses broke off the cliff and fell to near where they were standing and obliterated three survey points we had visited the previous day. We propose the auklet colony be named Massacre Valley in honor of the many fulmars and auklets that died in this landslide. Both crested and least auklets breed in the Hall Island colony, with crested auklets making up a larger proportion of birds seen during the day, especially in the center of the colony where the rocks (and therefore crevice sizes) are larger. Auklet attendance on the surface began earlier than 10 AM (on all days we visited the colony, auklets were attending the surface prior to our arrival) and continued until between 1630 and Our attendance counts on 26 July at two locations near the center indicated that crested auklets consisted of 74 and 78 percent of the total birds. Parakeet auklets (Aethia psittacula) were observed sporadically throughout the entire colony but made up a negligible percentage of the total birds. No other avian species besides McKay s buntings (Plectrophenax hyperboreus) apparently nested in the auklet colony, although northern fulmars nest on the cliffs above and may account for some amount of the guano observed on the high edges of the scree slopes. In apparent contrast to many auklet colonies recently visited (including those on St. Matthew), this colony on Hall Island appeared to have a relatively consistent density across the entire available habitat. Only three survey points were recorded as having potential habitat but no birds present and in these cases the scree was of marginal size for nesting crevices. All other points within the colony periphery showed evidence of activity. No auklets are present on the west coast of Hall Island south of Massacre Valley or on the east coast south of camp. During a beach walk north from camp we detected several tiny colonies along the west coast (Fig. 2). We did not survey north of the kittiwake colony shown in Figure 2. Presence/Absence and Density Surveys.--Forty-two of 123 plots visited had evidence of auklet activity (Appendix A), corresponding to an estimated two-dimensional colony area of 105,000 m 2 (42 x grid cell area of 2500 m 2 ). Droppings, feathers, and subsurface vocalizations were the most frequent indicator of birds present (Table 1). Because vegetation cover was scarce, vegetation wear was infrequently detected and feathers apparently blew away rather than persisting. In addition to the 42 plots with evidence of auklet activity, we noted that 9 additional sampling plots had auklet activity within 25 m (i.e.., there probably were auklets nesting within 6
7 the grid cell). If 51 grid cells had auklet activity, the upper range for colony area at this measurement scale would be 127,500 m 2. We used the presence/absence determination on each of the 120 density subplots to assess homogeneity. Within the 15 plots (all present ), 4.2% of subplots (5) were not classified as present. Counts of feathers and droppings on density plots are shown in Appendix B. Table 1.

11 St. Matthew Island Colony Description ( Pterodactyl colony).--this colony is located near the westernmost point of St. Matthew Island, centered about UTM V (60 34' N W). The colony site includes a remarkable variety of geological features and habitat types, including: steep inland talus slopes(figure 5; both active and inactive), cliffs (Figure 6), nearly level areas of stable unvegetated boulder fields (Figure 7), eroding coastal cliffs and talus (Figure 8), interspersed with meadows, mudflows and ponds (Figure 9). The colony site is about 1 km wide (northeast to southwest) and 750 m wide (northwest to southeast), and was accessible from both the north and south coastlines and from inland. Rocky slopes with breeding sites at this colony site face compass directions from northeast through west through south. Birds occupied breeding crevices as far as 500 m inland from the coastline and up to 150 m asl. No rockfalls were seen or heard during our visits to this colony. Both least and crested auklets breed at this site. We were not able to make any surface counts but the proportions of the two species did seem to vary considerably among different parts of the colony overall we were unable to see evidence of a bias towards either species. The colony has a strikingly patchy distribution, with isolated areas of high density scattered among wide areas of unsuitable habitat including grassy meadows. Northern fulmars had breeding sites on the main southwest-facing cliff face adjacent to the center of the colony. ILJ feels this is a medium-sized auklet colony with perhaps 30-50,000 breeding pairs of auklets present (both species combined). We found no evidence of vegetation encroachment into breeding habitat. Most of the rocky auklet breeding habitat at this colony appeared very old and at a climax vegetative stage consisting of crustose lichens. Colony Description ( Glory of Russia colony).--this colony is located southeast of Glory of Russia Cape, St. Matthew Island, centered about UTM ( N 'W). The colony site consists mostly of active talus slopes below cliffs up to 300 m high, with some birds using cliff crevices. The colony site is about 300 m wide (north to south) and 300 m wide (west to east), and was accessible from both the north and south coastlines and from inland. Rocky slopes with breeding sites at this colony site mostly face east. Birds occupied breeding crevices as far as 300 m inland from the coastline and to at least 250 m asl. GPS reception was poor under the cliffs making it difficult to locate plots. Frequent rockfalls were seen and heard during our visits to this colony, making it a highly dangerous place to visit. A huge mudslide less than 25 years old virtually bisects the colony (covering extensive areas used by breeding auklets in the 1970s, Art Sowls, pers. comm.). Both least and crested auklets breed at this site. ILJ feels this is a small-sized auklet colony with perhaps 3-5,000 breeding pairs of auklets present (both species combined). We were not able to make any surface counts but the proportions of the two species did seem to be biased towards crested auklets. Northern fulmars had breeding sites on the main southeast-facing cliff face north of the center of the colony. Most of the rocky breeding habitat at this colony appeared relatively new with little vegetation growth although some birds were breeding among vegetated boulders on top of a protruding, nearly inaccessible, mesa within the larger slide area.

17 Presence/Absence and Density Surveys (both St. Matthew Colonies).--Among 76 plots surveyed in the Pterodactyl colony, 23 had evidence of auklet activity (Appendix C), corresponding to an estimated colony area of 230,000 m 2 (23 x grid cell area of 10,000 m 2 ). We subjectively assigned 7 of these plots to a high density category, 6 to medium density and 10 as low density (Figure 11). Throughout much of the colony site, the patchy distribution of breeding birds meant that plots fell between occupied areas. Droppings were observed on every plot with auklets present (Table 1). In the Glory of Russia colony (Fig. 12), 14 of 54 plots visited had evidence of auklet activity (Appendix D), corresponding to an estimated colony area of 35,000 m 2 (14 x grid cell area of 2500 m 2 ). Droppings were observed on every plot with auklets present (Table 1). Quantitative density surveys were not conducted at the colonies on St. Matthew Island. ACKNOWLEDGEMENTS We thank Evie Witten and Anne Morkill for their hard work surveying the colonies on Hall and St. Matthew, respectively. Dave Klein kindly shared the aerial photos taken in 1953 which are used as a basis for the maps in this report. Randy Hagenstein spent lots of time visiting control points on Hall in order to georeference the photos. Sasha Kitaysky shared auklet phenology data from his visit in 2002 and this trip (summarized by Morgan Benowitz-Fredericks). We received safe and comfortable transport to the islands by the captain and crew of the M/V Tiĝlaˆx. 17
