Spring Migration of Eiders and Other Waterbirds at Point Barrow, Alaska
Birds migrating along the flaw lead at Point Barrow, Alaska were observed from 6 May to 4 June 1976. Little migration occurred until 25 and 26 May, when winds shifted from northeasterly to southwesterly and widened the lead. King Eiders (Somateria spectabilis) were the most abundant migrant; their m...

| description | Birds migrating along the flaw lead at Point Barrow, Alaska were observed from 6 May to 4 June 1976. Little migration occurred until 25 and 26 May, when winds shifted from northeasterly to southwesterly and widened the lead. King Eiders (Somateria spectabilis) were the most abundant migrant; their movements were greatest with southwesterly (following) winds and between 1200 and 1800 h (Alaska Daylight Savings Time). On 26 May 360 000 King Eiders passed within a 10-hour period. Ninety percent of the migrant Glaucous Gulls (Larus hyperboreus) moved east by 25 May. Common Eiders (Somateria mollissima) and Oldsquaw (Clangula hyemalis) were most abundant in early June and the bulk of their migration probably occurred after 4 June. Male King Eiders passed mostly in May while females were more common in June, suggesting that this species delays pair bonding until the latter part of their migration. This strategy necessitates an early migration and introduces the risk of possible starvation due to late spring freezing in the high Arctic /// On a observé du 6 mai au 4 juin 1976, des oiseaux en migration le long du chenal côtier à la point Barrow en Alaska. Peu de migration eut lieu avant les 25 et 26 mai, lorsque la direction du vent changea du nord-est au sud-ouest, élargissant le chenal. Les eiders respecTables (Somateria spectabilis) étaient les migrateurs les plus abondants, apparaissant en plus grands nombres suivant les vents du sud-ouest lorsque ceux-ci soufflaient, et surtout entre 12 h et 18 h (heure avancée de l'Alaska). Quatre-vingt-dix pour cent des goélands bourgmestres (Larus hyperboreus) avaient volé vers l'est avant le 25 mai. Les eiders communs (Somateria mollisima) et les canards à longue queue (Clanguia hyemalis) étaient plus abondants tôt en juin et la majeure partie de leur migration eut lieu probablement après le 4 juin. Les eiders respecTables mâles survolaient surtout en mai, tandis que les femelles passaient plutôt en juin, ce qui suggère que l'accouplement de cette espèce ne s'effectue qu'à un stade plus tardif que leur migration. Cette stratégie nécessite une migration plus tôt et présente le risque d'inanition dû au dégel tardif printannier dans l'Arctique boréal |
