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.

  • 5 inches, compact with a short tail

  • Slate-blue back and wings

  • Clean bright white face and belly

Voice

What it sounds like.

Nasal, honking 'yank-yank-yank' — sounds like a tiny toy horn. Contact call is a soft 'ip.'

Life & behavior

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.
