Lesser yellowlegs

The lesser yellowlegs (Tringa flavipes) is a medium-sized shorebird. The genus name Tringa is the New 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 flavipes is from Latin flavus, "yellow", and pes, "foot".[2]

Taxonomy

This species is similar in appearance to the larger greater yellowlegs, although it is more closely related to the much larger willet;[3] the fine, clear and dense pattern of the neck shown in breeding plumage indicates these species' actual relationships.

Description

The lesser yellowlegs is a medium-large shorebird. The legs are yellow. Compared to the greater yellowlegs, the bill is shorter (visually about the same length as the head), slim, straight, and uniformly dark. The breast is streaked and the flanks are finely marked with short bars.[4]

Measurements:[5]

  • Length: 9.1-10.6 in (23-27 cm)
  • Weight: 2.8-3.2 oz (79.5-90.9 g)
  • Wingspan: 23.2-25.2 in (59-64 cm)

Breeding

Their breeding habitat is clearings near ponds in the boreal forest region from Alaska to Quebec. They nest on the ground, usually in open dry locations.

Migration

They migrate to the Gulf coast of the United States, the Caribbean, and south to South America. This species is a regular vagrant to western Europe; in Great Britain about five birds arrive each year, mostly between August and October,[6] with the occasional individual overwintering.

Diet

These birds forage in shallow water, sometimes using their bill to stir up the water. They mainly eat insects, small fish and crustaceans.

Call

The call of this bird is softer than that of the greater yellowlegs.
