The sparrowhawk is a yellow eyed hawk
with short, rounded wings and a long
dark striped tail. The male sparrowhawk tercel (formerly musket)
is about 30cm long. The female (hawk) is bigger and measures about
  more...38cm. The male sparrowhawk has a brownish back and wings, and has characteristic dark striped underparts.
Another distinguishing feature of the female sparrowhawk is the white stripe behind each eye. Both the male and the female have a wingspan of approximately 66cm.
The sparrowhawk has yellow legs and strong talons in which to carry prey. Its hooked beak enables the sparrowhawk to tear prey into pieces small enough to swallow. As its name suggests the sparrowhawk preys mostly on small birds. It also eats small mammals and insects.
Sparrowhawks, like all birds of prey, create a small parcel of those parts of
their prey, such as fur, bones and feathers, which they find to be
indigestible. This is called a pellet. They
regurgitate these and they may be found
on the ground near their eating place.

The nest of the sparrowhawk is made of twigs and sticks and is lined with dead leaves. The nest is bulky and is usually built 10–12 metres above the ground in a tree. A clutch of four to six eggs is laid
which are greenish-white with brown streaks. Young sparrowhawks have a
voracious appetite, and need to eat two to three ‘sparrow-sized’ birds each day.
