1 Species no. 44: Grey Plover Pluvialis squatarola Distribution: This plover has a circumpolar distribution, and inhabits tundra on arctic islands and the shores of the Arctic Ocean. Movements: Migratory. The birds breeding from North-western Europe to the Taymyr Peninsula are visiting Western Europe, where many of them are wintering. Part of this population is reaching the coasts of West Africa, southwards to the Gulf of Guinea. More eastern birds pass Greece while migrating to East Mediterranean regions and Eastern Africa. Population size and trends: This plover breeds in most of arctic Russia, with the European part accounting for only a tiny proportion of its global breeding range (2,100 10,500 pairs, BirdLife Int. 2004A). No trend data were available for , but there is no evidence to suggest that the species declined. It is not breeding in EU 27. The Eastern Atlantic wintering population occurring from the Wadden Sea, Britain, Ireland south to West Africa is estimated at 247,000 individuals and decreasing (Delany & Scott 2006). Biological and behavioural aspects: Breeding: clutch size: 4 eggs (sometimes 3); incubation: days; full flight of young birds at days. Brood: 1. Reproduction & Prenuptial Migration * 264 *

5 Species no. 45: Lapwing Vanellus vanellus Distribution: In Palearctic, this plover inhabits boreal, temperate, steppe and Mediterranean regions of Europe and Asia, from Iberia to Finland and the British Isles to China. It breeds also in very small number in North Africa. Movements: Mainly migratory, though some western and southern sub-populations only partially so. Sensitive to prolonged cold spells. European populations winter in maritime climate from the British Isles to Morocco, and the Mediterranean regions. Britain, Ireland and Denmark constitute the northernmost regular wintering areas. In more northern wintering areas occasional spells of very cold weather in winter lead to pronounced movements, which can occur any time between autumn and spring passages. Spring passage begins early- from late January in southern wintering areasand in temperate Europe is at peak in early March. Population size and trend: The European breeding population numbers 1,700,000-2,800,000 pairs (BirdLife 2004A) of which 870,000-1,400,000 breeds in EU 27 (BirdLife Int. 2004A, 2004B). Although several small populations were stable or increased during , the species suffered declines across much of Europe, most notably the sizeable populations in the United Kingdom, the Netherlands and Russia and underwent a large decline (>30%) overall (BirdLife Int. 2004A). In most regions this species declined following wetland reclamation, intensification of agriculture and use of pesticides and chemicals. Biological and behavioural aspects: Breeding: clutch size is usually 4 eggs, sometimes 3, rarely 2 or 5; incubation: days; fledging period: days. Brood:1. Reproduction & Prenuptial Migration * 268 *

12 Species no. 46: Knot Calidris canutus Distribution: This bird has a circumpolar breeding distribution in tundra, and the most important populations are found in North America, Greenland and eastern Siberia. The Knot is not breeding in the European Union. Movements: Migratory. Birds visiting Europe belong to two distinct populations. C. c. islandica which breed in North Eastern Canada and Greenland and winter along the coasts of North Western Europe (British Isles, the Netherlands and France). C. c. canutus, which breed in Svalbard and Taymyr and winter in two coastal wetlands in West Africa visit Europe only on migration (with an important spring staging area in the Wadden Sea). Population size and trends: The population of islandica amount to about 450,000 individuals (Delany & Scott 2006). This population increased from late 1970s until 1990s but has since decreased (Delany & Scott 2006). The canutus population is estimated at 400,000 birds and the trend is unknown (Delany & Scott 2006). Biological and behavioural aspects: Breeding: clutch size is 3-4 eggs; incubation: days; full flight of young birds at ca days. Brood: 1. Reproduction & Prenuptial Migration * 275 *

16 3) The beginning of the period of prenuptial migration ranges from the 2 nd decade of January (DE?) to the 2 nd decade of May (FI, SE, NL). Species no. 47: Ruff Philomachus pugnax Distribution: The species has a large Palearctic distribution across the boreal and Arctic zones of Eurasia. In Europe, most birds breed in Fennoscandia and Russia and sparsely in northwest Europe and the Baltic States. The breeding habitats are lowlands tundra or bogs in the North and wet meadows or coastal marshes in the south. The latter now holds only a small fraction of the population. Movements: Most birds winter in sub-saharan Africa, but some migrate to India, the Middle East and small numbers occur in Europe. Population size and trends: The European population is estimated to 200, ,000 pairs with the major part of this population breeding in Russia 140, ,000 pairs (BirdLife Int. 2004A). The population in EU 27 is estimated to 51,000 71,000 pairs (BirdLife Int. 2004B). During most populations, including the core populations in Sweden and Russia, declined moderately (>10%) (BirdLife Int. 2004A). Biological and behavioural aspects: Breeding: clutch sizes usually (2-) 4 eggs; incubation: days; fledging period: days and becomes independent at or before fledging as the female, who is the only parent caring for the young, sometimes depart before fledging of the young; brood: 1.

22 Species no. 48: Jack Snipe Lymnocryptes minimus Distribution: The Jack Snipe is breeding in boreal regions of North Eastern Europe and Siberia. Movements: Migratory. The birds of Europe and western Siberia are wintering in Western and South Western Europe and in North Western Africa. Population size and trends: The European breeding population amounts to 18,000-70,000 breeding pairs (BirdLife Int. 2004A). The European Union breeding population is estimated at 12,000-19,000 pairs (BirdLife Int. 2004B). The status of the Jack Snipe remains relatively unknown, and consequently it is not yet possible to determine long-term population trends. During the populations are believed to have remained stable in most countries but the large population in Russia declined (BirdLife Int. 2004A). Biological and behavioural aspects: Breeding: clutch size is (3)-4 eggs; incubation: at least 24 days; fledging period: not recorded but probably 2-3 decades after hatching as other snipes; brood: normally one but two broods suspected but no proof.

28 Species no. 49: Common Snipe Gallinago gallinago Distribution: The Common Snipe (excluding G. delicata from the Nearctic) has a large Palearctic breeding distribution. It winters in Europe, North and sub-saharan Africa, the Middle-East, India and south-east Asia. Within Europe the species is a widespread breeder from Iceland to Russia above approximately 50 N. The main wintering range extends from the British Isles, Denmark, Belgium, the Netherlands and France south to Iberia and North Africa, eastwards through the Mediterranean basin to Turkey and the Middle-East. Two subspecies occur in Europe G. g. faeroeensis which breeds in Iceland and the Faeroes, and the nominate race which occurs elsewhere in Europe. Movements: The species is mostly migratory in Europe, though some birds in the western maritime countries are only partially migratory or even resident. Fennoscandian populations mainly winter in Ireland, Britain, France and Iberia. Some of these birds winter in Denmark and the Netherlands. Birds moving through southern Fennoscandia include birds from Northwest Russia. Return migration starts in February in Iberia, and March elsewhere, breeding grounds being occupied in April-May. Population size and trends: The population is estimated to 930,000 1,900,000 pairs in Europe of which 300, ,000 breeds in Russia (BirdLife Int. 2004A). The population in the European Union amounts to 300, ,000 pairs (BirdLife Int. 2004B). Eastern European populations appear to be currently stable. In contrast the western European populations have declined during (BirdLife Int. 2004A). Biological and behavioural aspects: Breeding: clutch size: usually 4 eggs (2-5); incubation: days; fledging period: days; independent before or soon after fledging; broods: probably only one brood.

Full flight of young birds indicates the end of the reproduction period (c. 2 decades after hatching), but difficult to notice in the field. Reproduction & Prenuptial Migration * 294 *
