Western Rock Nuthatch Sitta neumayer

Typical-looking nuthatch with gray upperparts, dingy white underparts, and a black mask. Favors mountainous rocky areas, and is often seen actively feeding on boulders and cliffs, not normally on trees. Builds a unique, huge mud nest that it sticks to cliffs and rocks and uses year-round. Song and call are a loud and bubbling series of descending whistles “Piu-piu-piu-piu…” or “Pi pi pi pu-pu-pu-pu…” Somewhat similar to Eurasian Nuthatch, but larger, longer- and stronger-billed, and uses different habitats. Eastern Rock Nuthatch is also similar, but larger and heavier than the present species, with an even larger bill and thicker black eye stripe.
