Lesser Yellowlegss are medium-sized waders. The two sexes
look alike. Their
eclipse
plumage
is cryptic.
During the
non-breeding
season they have an almost entirely white
front, from throat to undertail coverts, with only some
fine grey streaking on throat and chest. The rump
is also white. The back, cap, sides of the head and neck are
grey with darker streaking, while the eyes are surrounded
by thin white eye-rings. The scapulars are dark-grey with
white edge lining. The wings are dark-grey, with whitish
edge-lining and a brownish tinge.
In-flight they show no wing bar, but a prominent white back
and rump and the yellow feet protrude clearly beyond the tail.
The tail is barred black and
white. The white supercilium is short, visible only in front of the
eye.
The eyes have dark irises. The dark-grey bill is thin and straight
and only just a bit longer than the size of the head.
The long legs and feet are yellow.
Juveniles
roughly resemble
non-breeding
adults.
The correct identification of waders ("shorebirds"), e.g. of the
Calidris, Tringa, Actitis etc.
or of the
Charadrius, Pluvialis and related
genera in the field can be quite tricky. We have therefore made an attempt
to give some advice
HERE.

The Lesser Yellowlegs is a strongly migratory species.
Its breeding range encompasses large parts of North America north of
ca. 50 degrees latitude, from around the southern tip of Hudson Bay,
Canada, to most of Alaska, US (except the western and northern coastal
fringes).
Outside the breeding season they are found on migration throughout the
US. Their winter quarters extend from the southern North American coastal
fringe, from the Carolinas in the East and California in the West,
southwards, throughout central America, the Caribbean and into all of
South America, down to Cape Hoorn, and the Falkland Islands. They are
usually not found in southern Chile and only rarely in the Amazon
jungle.
In Europe Lesser Yellowlegs appear as vagrants during the non-breeding
season. Sightings have been reported mostly along the western coastal
fringe, from around Britain and Ireland, but also from the continental
coastline, from southern Scandinavia (including the Baltic Sea) to
around Iberia.
Lesser Yellowlegss breed in clearings around ponds in boreal forest.
Outside the breeding season in Europe they are found mostly in coastal
aquatic habitats, whereas in Central and South America they are present
throughout the continent.
