The wallcreeper (Tichodroma muraria) is surprisingly difficult to see on mountain faces – often hiding if it senses danger. It has stunning crimson, grey and black plumage, butterfly-like flight and inaccessible haunts. In the breeding season, the male can often be distinguished from the female (depicted) by its black throat. It occurs in several types of rocky areas with steeps, cliffs and boulder-strewn slopes and gorges in the mountains of Eurasia from southern Europe to central China. Previously associated to nuthatches and creepers, the Wallcreeper is today the single member of the Family Tichodromadidae.
