The wallcreeper is a small passerine of the high mountains of the Palearctic, from southern Europe to central China, and the only living member of its genus and family. It breeds at 3,600 to 5,100m in the Himalaya and is resident across much of the range, including India, Nepal, Bhutan and parts of Tibet, and a winter visitor in Bangladesh (Wikipedia, general species account).
Its plumage is primarily blue-grey, but its most striking feature is the crimson wings with white spots; in summer males have a black throat, while in autumn and winter both sexes have a white throat. The female usually lays four or five white eggs speckled black or reddish brown and incubates them for 19 to 20 days, and both parents feed the nestlings for 28 to 30 days until they fledge.
