zedníček skalní Tichodroma muraria

Unmistakable, but difficult to spot on rock faces. Spectacular in flight, with broad black, red, and white-spotted wings resembling a giant butterfly. Usually found on rock faces in high mountainous regions, but also breeds in steep gorges lower down and can even be found on tall buildings in winter. Breeding male has a black throat; winter males and all females have white throats. Rarely-heard song is a steadily rising whistle.
