Wallcreeper

Tichodroma muraria

A jewel of mountain cliffs, the Wallcreeper flashes crimson wing patches as it flutters along vertical rock faces like a giant butterfly. Its grey plumage, curved bill, and broad rounded wings make it unmistakable. Found across the high mountains of Europe and Central Asia, it probes crevices for insects and spiders with its slender, decurved bill.
