The sparrowhawk (Accipiter nisus) is a small bird of prey in the Accipitridae family. Adult male sparrowhawks have bluish grey upperparts and orange-barred underparts; females and juveniles are brown above with brown barring below.
The female is up to 25% larger than the male. Sparrowhawks breed in suitable woodland of any type. Four or five pale blue, brown-spotted eggs are laid. The chicks hatch after 33 days and fledge after 24 to 28 days.
