📖 1. Overview

The white-bellied woodpecker is a large woodpecker about 46 cm long with a white belly and glossy black plumage elsewhere. In Korea, Gwangneung Forest was known as its breeding site, but with no confirmed records since 1993 it is considered extirpated in the country.

🦴 2. Anatomy & Morphology

Males have a red crown and cheek patch beside the bill, whereas these are black in females. Its bill is greenish-yellow with a black tip.

🔍 3. Ecology & Behavior

It nests in holes it excavates in old trees or in natural cavities, laying 2–4 eggs in April–May (months 4–5), and the male incubates longer than the female. Chicks are fed mainly beetle larvae and ants, and in autumn adults also eat tree fruits.

🇰🇷 4. Connection to Korea
