A sharp “chek”. Song a short series of clattering noises (said to sound like a paper bag full of dried peas being shaken).

Lesser Whitethroats are among the smallest warblers breeding in Finland. Their distinguishing features include a grey cap, dark colouring extending behind the eyes, and a white throat. They have brownish grey backs and pale underparts. Males and females have the same colouring. They resemble Whitethroats, but have shorter tails, greyer upper parts, whiter underparts, and no reddish brown colouring on their wings. Their legs are dark bluish grey, their beaks are black (with a paler base to the lower mandible) and their irises are brownish grey.
