White-breasted Nuthatch
Sitta carolinensis
Sittidae
The upside-down bird. Small, compact, and famous for creeping headfirst down tree trunks — no other yard bird moves this way. Slate-blue back, clean white face and belly, black cap on males (dark gray on females). Constantly vocal and easy to spot once you learn its nasal 'yank-yank' call.
How to spot one.
5 inches, compact with a short tail
Slate-blue back and wings
Clean bright white face and belly
Black cap (male) or dark gray cap (female)
Habitually walks headfirst DOWN tree trunks
What it sounds like.
Nasal, honking 'yank-yank-yank' — sounds like a tiny toy horn. Contact call is a soft 'ip.'
How it lives.
Cavity nester. Caches seeds and nuts in bark crevices, jamming them into place with the bill (the origin of 'nut hatch' — 'hatch' from 'hack'). Joins mixed winter flocks. Territorial and generally sedentary — a pair stays in the same acre of woods year after year.
