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 chesnut 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 males, compete for nesting territory, and will aggressively defend their nests and chosen mates. Once
the females lay their eggs, they begin their southward migration, leaving the males to incubate the eggs and look after the
young. Three to seven eggs are laid in a ground nest near a marshy area. The young mainly feed
themselves and are able to fly within 20 days of birth.
Red-necked Phalarope chick.
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. This species is often very tame and approachable.
The Red-necked Phalarope is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory
Waterbirds (AEWA) applies.
Red-necked Phalarope 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.
