|Range map of the Red-necked Phalarope: Breeding grounds (red) and wintering grounds (blue)|
The Red-necked Phalarope (Phalaropus lobatus) is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, winters at sea on tropical oceans.
Red-necked Phalarope is about 18 cm (7 in) in length, with lobed toes and a straight, fine bill. The breeding female is predominantly dark grey above, with a chestnut neck and upper breast, black face and white throat. The breeding male is a duller version of the female. They have lobed toes to assist with their swimming. Young birds are grey and brown above, with buff underparts and a black patch through the eye. In winter, the plumage is essentially grey above and white below, but the black eyepatch is always present. They have a sharp call described as a whit or twit.
The typical avian sex roles are reversed in the three phalarope species. Females are larger and more brightly coloured than males. The females pursue and fight over males, and will defend their mate from other females until the clutch is complete and the male begins incubation. The males perform all incubation and chick-rearing activities, while the females may attempt to find another mate. If a male loses his eggs to predation, he may re-pair with his original mate or a new female to try again. Once it becomes too late in the breeding season to start new nests, females begin their southward migration, leaving the males to incubate the eggs and look after the young. Clutch size is usually 4, but can be fewer. The young mainly feed themselves and are able to fly within 20 days of hatch.
When feeding, a Red-necked Phalarope will often swim in a small, rapid circle, forming a small whirlpool. This behaviour is thought to aid feeding by raising food from the bottom of shallow water. The bird will reach into the center of the vortex with its bill, plucking small insects or crustaceans caught up therein. On the open ocean, they are often found where converging currents produce upwellings. During migration, some flocks stop over on the open waters at the mouth of the Bay of Fundy to take advantage of food stirred up by tidal action.
Almost all of the nonbreeding season is spent in open water. As this species rarely comes into contact with humans, it can be unusually tame.
The Red-necked Phalarope is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
In Britain and Ireland
The Red-necked Phalorope is a rare and localised breeding species in the British Isles, which lie on the extreme edge of its world range. The most reliable place for them is the Shetland Isles, particularly the Loch of Funzie on Fetlar, with a few birds breeding elsewhere in Scotland in the Outer Hebrides (e.g. at Loch na Muilne, where a "phalarope watchpoint" has been set up) and sometimes the Scottish Mainland in Ross-shire or Sutherland. They have also bred in western Ireland, although there are very few breeding records since the 1970s.
