The name Phalarope refers to any of three species of slender-necked
shorebirds in the genus Phalaropus of the bird family Scolopacidae.
They are 6–10 in (15–25 cm) in length, with lobed toes and a
straight, slender bill. Predominately grey and white in winter, their plumage
develops reddish markings in summer. They are especially notable for
two things: their unusual nesting behavior, and their unique feeding
technique.
- Family: Scolopacidae (part)
Nesting behavior
The typical avian sex roles are reversed in the three Phalarope species. Females are larger and more brightly colored 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 care for the young.
Feeding technique
When feeding, a phalarope will often swim in a small, rapid circle,
forming a small whirlpool. This behavior 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.
Habitat
Red and Red-necked Phalaropes are unusual amongst shorebirds in that they are considered pelagic, that is, they spend a great deal of their lives outside the breeding season well out to sea.
Phalaropes are unusually halophilic (salt-loving) and feed in great numbers
in saline lakes such as Mono Lake in California and the
Great Salt Lake of Utah.
Range
Two species, the Red Phalarope (Phalaropus fulicaria) (called Grey Phalarope in Europe) and Red-necked Phalarope (P. lobatus) breed around the Arctic Circle and winter on tropical oceans.
Wilson's Phalarope (P. tricolor) breeds in western North America and migrates to South America.
