Pomarine Jaeger (Stercorarius pomarinus) is a visitor to coastal regions of India. Size: 56 cm Description: Occurs in two colour morphs or phases, and various intermediate ones. All plumages: Bill hooked, feet webbed. Adults in dark morph: Generally dark brown, slightly lighter below and on cheeks; black cap. Adults in light morph: Underparts, breast, neck and face white: cheeks, and throat in some cases, tinged with yellow; cap black; rest of upperparts dark brown; dark barring may occur on flanks, breast and underparts; bases of the primary feathers are white, providing a fairly conspicuous white "wing-flash"; tips of the central tail feathers are spatulate and twisted, and project several centimeters beyond the outer ones. Juveniles: grayish brown, heavily barred on upperparts and underparts with blackish brown; central tail feathers are little elongated. Range: Circumpolar. Breeds on the Arctic islands and mainland across North America. Winters mainly at sea from the Virginia coast south to the West Indies, from California to Peru, and off the western coast of Africa. Remarks: Jaegers are freebooters of the open sea, preying on other forms of marine birdlife; they are known to fishermen as "sea hawks." This plucky member of the jaeger subfamily has been known to attack the much larger Great Black-backed Gull and successfully steal its prey. |
