Falaropo Picofino

Identificación

The red-necked phalarope is about 18 cm (7.1 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. They have a white wing stripe which helps distinguish this bird from the similar Wilson's phalarope. 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.

Taxonomía

In 1743, the English naturalist George Edwards included an illustration and a description of the red-necked phalarope in the first volume of his A Natural History of Uncommon Birds. He used the English name "The coot-footed tringa". Edwards based his hand-coloured etching on a specimen that had been collected off the coast of Maryland. When in 1758, the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the red-necked phalarope with the phalaropes and sandpipers in the genus Tringa. Linnaeus included a brief description, coined the binomial name Tringa lobata and cited Edwards' work. The red-necked phalarope is now placed in the genus Phalaropus that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The English and genus names 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 lobatus is Neo-Latin for "lobed". The species is monotypic: no subspecies are recognised.
