The female is duller overall, in particular having browner face mask, pale buffy-brown breast, and a buff supercilium and malar stripe, and smaller or no white wing patches. Males in immature and winter plumage and are similar to females, except that adult males retain the white wing patches all year.

S. maura, which (also being a long-distance migrant) shares the longer wingtips; however, Siberian Stonechat can be distinguished by its conspicuous unmarked pale orange-buff rump (in Whinchat, the rump is the same mottled brown colour as the back).
Its main call is a
hue-tac-tac, the 'tac' softer and less grating than that of the European Stonechat; the call is used both for contact between birds and predator alarms. The male has a whistling, crackly but soft song used during the breeding season, consisting of a mixture of soft whistles, tacs and more grating sounds; it is often mimetic, including phrases from the songs of at least 12 other assorted bird species. On the wintering grounds, it often gives alarm calls but only occasionally sings, particularly at the end of winter when starting spring migration.

s until the new tree crop is about 5–6 years old and a metre or two tall. It always needs at least a few perching points (shrubs, tall weeds, or fenceposts) to scan from for food and use as songposts. It nests in dense low vegetation, laying from four to seven eggs, which hatch after 11–14 days. The young leave the nest on foot 10–14 days after hatching, while still too young to fly; they then fledge at 17–19 days after hatching and remain largely dependent on the parents for up to a further two weeks after fledging. Whinchats are short-lived, typically only surviving two years, to a maximum recorded of just over five years; breeding starts when birds are a year old. Predators include

, primarily in autumn. The birds like to perch on elevated spots such as shrubs, from where they make sallies to catch insects, mostly taken off the ground, but also flying insects. While so perched, males in particular frequently flick their tail and sometimes their wings to show the white tail and wing flashes, for display or territorial communication signals to other Whinchats.
Adult Whinchats have a single complex complete moult in late summer (late July onward) after breeding and mainly completed before southbound migration. Juveniles have a partial moult at the same time, growing new body feathering but retaining the flight feathers. All ages also have a partial moult in early spring on the wintering grounds before northbound migration.
