Black-naped woodpecker

Thai: นกหัวขวานเขียวหัวดำ, nok hua khwaan khiew hua dam

Binomial name: Picus guerini, Johann Friedrich Gmelin, 1788

The grey-headed woodpecker (Picus canus), also known as the grey-faced woodpecker, is a Eurasian member of the woodpecker family Piciformes.

Description

It is 25–28 cm long and weighs 130-180 grams. Its plumage closely resembles its near relative the European green woodpecker. It has green upperparts, pale grey underparts and a yellow rump. It has a grey head with black moustache, and the male has a red crown. It has a shorter neck, slimmer bill and slightly rounder head than the green woodpecker.

Behaviour

Grey-headed woodpeckers live in leaf forests and mixed forests. They breed in May and lay five to ten eggs which are brought up by both parents. The young hatch after 15–17 days, and learn to fly in four weeks.

In summer, the grey-headed woodpecker eats maggots, beetle larvae and other insects. In winter it takes seeds, and can even come to garden feeding places, especially if fat is offered.

Name

The Sibley-Monroe checklist has two birds called "grey-headed woodpecker", Picus canus and Dendropicos spodocephalus (syn.Mesopicos goertae). For the latter, see grey woodpecker.
