Wilson's phalarope (Phalaropus tricolor) is a small wader. This bird, the largest of the phalaropes, breeds in the prairies of North America in western Canada and the western United States. It is migratory, wintering in inland salt lakes near the Andes in Argentina. [2] They are passage migrants through Central America around March/April and again during September/October. [3] The species is a rare vagrant to western Europe.
This species is often very tame and approachable. Sometimes it is placed in a monotypic genus Steganopus.
This bird is named after Scottish-American ornithologist Alexander Wilson. [4] The English and genus names for phalaropes come through French phalarope and scientific Latin Phalaropus from Ancient Greek phalaris, "coot", and pous, "foot". Coots and phalaropes both have lobed toes. The specific tricolor is from Latin tri-, "three-", and color, coloris "colour". [5] [6]
Wilson's phalarope is slightly larger than the red phalarope at about 23 cm (9.1 in) in length. It is a dainty shorebird with lobed toes and a straight fine black bill. The breeding female is predominantly gray and brown above, with white underparts, a reddish neck and reddish flank patches. The breeding male is a duller version of the female, with a brown back, and the reddish patches reduced or absent.
Measurements: [7]
In a study of breeding phalaropes in the province of Saskatchewan, Canada, females were found to average around 10% larger in standard measurements and to weigh around 30% more than the males. Females weighed from 68 to 79 g (2.4 to 2.8 oz), whereas males average 51.8 g (1.83 oz). [8]
Young birds are grey and brown above, with whitish underparts and a dark patch through the eye. In winter, the plumage is essentially grey above and white below, but the dark eyepatch is always present. The average longevity in the wild is 10 years. [9]
Wilson's phalaropes are unusually halophilic (salt-loving) and feed in great numbers when on migration on saline lakes such as Mono Lake in California, Lake Abert in Oregon, and the Great Salt Lake of Utah, often with red-necked phalaropes.
When feeding, a Wilson's 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 outskirts of the vortex with its bill, plucking small insects or crustaceans caught up therein.
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. Three to four eggs are laid in a ground nest near water. The young feed themselves.
Although very common, this bird's population may have declined in some areas due to the loss of prairie wetland habitat. A few staging areas are of critical importance during migration.
A phalarope is any of three living species of slender-necked shorebirds in the genus Phalaropus of the bird family Scolopacidae.
The semipalmated sandpiper is a very small shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific pusilla is Latin for "very small".
The dunlin is a small wader, formerly sometimes separated with the other "stints" in the genus Erolia. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from dun, "dull brown", with the suffix -ling, meaning a person or thing with the given quality.
The solitary sandpiper is a small shorebird. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific solitaria is Latin for "solitary" from solus, "alone".
The American golden-plover, is a medium-sized plover. The genus name is Latin and means relating to rain, from pluvia, "rain". It was believed that golden plovers flocked when rain was imminent. The species name dominica refers to Santo Domingo, now Hispaniola, in the West Indies.
The Pacific golden plover is a migratory shorebird that breeds during summer in Alaska and Siberia. During nonbreeding season, this medium-sized plover migrates widely across the Pacific.
The western sandpiper is a small shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific mauri commemorates Italian botanist Ernesto Mauri (1791–1836).
The white-rumped sandpiper is a small shorebird that breeds in the northern tundra of Canada and Alaska. This bird can be difficult to distinguish from other similar tiny shorebirds; these are known collectively as "peeps" or "stints".
The long-billed dowitcher is a medium-sized shorebird with a relatively long bill belonging to the sandpiper family, Scolopacidae. In breeding plumage, adults are characterized by a beautiful rufous head and underparts with a darker mottled back and a large white upper rump only seen in flight. They feed in various freshwater habitats with their bill underwater in a "sewing machine" motion and are known to have an exciting mating display where males chase females in flight. The genus, Limnodromus is Ancient Greek from limne, "marsh" and dromos, "racer". The specific scolopaceus is Neo-Latin for "snipe-like", from Latin scolopax, scolopacis, a snipe or woodcock. The English name is from Iroquois and was first recorded in 1841.
The long-billed curlew is a large North American shorebird of the family Scolopacidae. This species was also called "sicklebird" and the "candlestick bird". The species breeds in central and western North America, migrating southward and coastward for the winter.
The red-necked phalarope, also known as the northern phalarope and hyperborean phalarope, 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.
The red phalarope or grey phalarope is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, migrates mainly on oceanic routes, wintering at sea on tropical oceans.
The ruff is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia.
The Eurasian dotterel, also known in Europe as just dotterel, is a small wader in the plover family of birds. It is the only species placed in the genus Eudromias.
The stilt sandpiper is a small shorebird. The scientific name is from Ancient Greek. The genus name kalidris or skalidris is a term used by Aristotle for some grey-coloured waterside birds. The specific himantopus means "strap foot" or "thong foot".
The African jacana is a wader in the family Jacanidae. It has long toes and long claws that enables it to walk on floating vegetation in shallow lakes, its preferred habitat. It is widely distributed in sub-Saharan Africa. For the origin and pronunciation of the name, see Jacanidae.
Wilson's plover is a small bird of the family Charadriidae.
Kittlitz's plover is a small shorebird in the family Charadriidae that breeds near coastal and inland saltmarshes, sandy or muddy riverbanks or alkaline grasslands with short vegetation. It is native to much of Sub-Saharan Africa, the Nile Delta and Madagascar. It is thought to be mainly polygamous and has monomorphic plumage.
The wattled jacana is a wader in the family Jacanidae found throughout much of South America east of the Andes, as well as western Panama and Trinidad. It is the only species in the Jacanidae family with such a large distribution. Wattled jacanas have long toes and claws which help them walk through aquatic vegetation. Like the majority of species of jacanas, the female is larger than the male, and forms harems of up to 4 or 5 males at any given time. There is also a major difference in proportional development or ornamentation and defense relative to body size when compared to males.
The collared plover is a small shorebird in the plover family, Charadriidae. It lives along coasts and riverbanks of the tropical to temperate Americas, from central Mexico south to Chile and Argentina.
