Great Spotted Woodpecker
Great
Spotted Woodpeckers are about the same size as Starlings.
They are common birds of parkland and woodland but often
feed in gardens. Great Spotted Woodpecker juveniles have
red foreheads that are replaced by black as they moult in
the autumn. Adult males then have a red nape but females
have no red on their head at all and all these differences
in plumage are easy to see.
Although attractive, Great Spotted
Woodpeckers can make themselves unpopular by drilling holes
in nest boxes and eating young birds. To get them to use
nest boxes you need to put a lump of soft wood inside, so
that they can hollow out the nest cavity for themselves.
The male sits on the nest at night and a female may well
use a near-by nest box to roost in.
