Why do great spotted woodpeckers ‘drum’ their beaks on trees?
You are correct.
Hmmm... that's not right.
|The great spotted woodpecker is a medium-sized woodpecker. It nests in holes that it excavates in trees in broadleaved woodlands, large parks and gardens. It has a distinctive, bouncing flight, but is mostly likely to be heard, rather than seen, as it ‘drums’ away at a tree trunk during its breeding displays. The male has a distinctive red patch on the back of the head and young birds have a red crown.
