Marsh Sandpipers are small waders.
Their plumage
is cryptic.
During the non-breeding
season they basically have a white front
and a grey back. Except for the sides of the chest, which are
streaked grey, the entire front, from throat to undertail
coverts, including the flanks, is white. The head, except for
white frons, eyebrows and chin, is white with grey striation.
The nape of the neck and the wings are grey, with fine white
edge lining.
In-flight they do not show a wing bar, but a prominent white back.
During the breeding
season, except for white eye-rings, the
head, neck, throat, chest and flanks become streaked grey-brown.
The wings develop brownish colours. The light-brown base contrasts
with dark-brown patches and white edges, most prominently on
the scapulars.
The eyes have dark irises. The dark-grey bill is straight, very
slim and longer than the size of the head. The legs and feet are
olive-grey. The legs are long and in-flight the feet protrude
clearly beyond the tail.
Juveniles
roughly resemble
non-breeding adults,
but they have very crisp, fine white edge-lining on their wing
feathers and browner coverts and tertials.

Twitcher's tip |
|
Compared to other species of small sandpipers and stints, Marsh Sandpipers
have the slimmest straight black bill.
The correct identification of waders ("shorebirds"), e.g. of the
Calidris, Tringa, Actitis and
related families 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.
