The great spotted woodpecker /Dendrocopos major
14.
When hidden by the foliage, its presence is often advertised by the mechanical drumming, a vibrating rattle, produced by the rapidly repeated blows of its strong bill upon a trunk or branch. The drumming of this species is shorter than that of the lesser spotted woodpecker, and fades away at the end.
The food mainly consists of insects and grubs but also seeds, fruit, scraps, eggs, chicks and small rodents. The woodpecker usually alights on the trunk, working upwards, from side to side, but sometimes will perch in passerine style, when it sits well upright.
