The wallcreeper is a small passerine bird found throughout the high mountains of the Palearctic from southern Europe to central China. It is the only extant member of both the genus Tichodroma and the family Tichodromidae.
Region
Palearctic high mountains
Typical Environment
Breeds on steep rocky cliffs, gorges, and crags from the Pyrenees and Alps across central Asia to western China. Outside the breeding season it disperses downslope, frequenting quarries, ravines, bridges, dams, and large stone buildings. Prefers rugged, vertical rock with abundant crevices for foraging and nesting. Nests are tucked deep in fissures or cavities, often well hidden from predators.
Altitude Range
Sea level to 3500 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
The wallcreeper is the only living member of both its genus and family, making it taxonomically unique. It flutters along cliff faces with a distinctive butterfly-like flight, flashing crimson wing patches. Skilled at gleaning insects from tiny crevices, it often descends to lower elevations and even visits buildings, dams, and quarries in winter.

Temperament
solitary and territorial
Flight Pattern
fluttering, butterfly-like with short rapid wingbeats
Social Behavior
Usually solitary outside the breeding season, methodically working rock faces. Pairs form in spring and nest in deep crevices, where 3–5 eggs are laid. Both parents feed the nestlings, and territories are defended with conspicuous wing-fanning displays.
Migratory Pattern
Partial migrant
Song Description
A series of thin, high-pitched whistles and trills that carry along cliffs. Calls include sharp, piercing notes used to maintain contact on sheer rock faces.
Plumage
Soft slate-grey body with broad crimson panels in the wings and black flight feathers marked with small white spots.
Diet
Primarily small insects and spiders gleaned from rock crevices, including beetles, flies, and their larvae. It probes into fissures with its long, delicate bill and occasionally hawks insects in short sallies. In winter it continues to glean on man-made structures that mimic cliff habitat.
Preferred Environment
Vertical rock faces, canyon walls, and quarry sides where crevices are abundant. In non-breeding seasons it also feeds on large buildings, bridges, and dam walls.
