[edit] Habitat

Open fields, or feeding in small groups along a roadside. They will come into town parks and villages.

[edit] Behaviour

[edit] Breeding

Nesting is in large colonies.
The nest is built high in a tree close to other nests. The nest is bulky and made from twigs bound together with earth, lined with moss, leaves, grass, wool, and hair. Previous years' nests may be renovated and reused. Three to nine eggs are laid which are smooth, glossy and light blue, greenish-blue or green with dark spots. The eggs are about 40 mm long. The female incubates the eggs for 16-20 days. Both parents feed the young after they have hatched.

[edit] Diet

The diet includes insects, worms, carrion and seeds. They will visit bird tables for scraps and fruit.

[edit] Vocalisation

Call: "kaaa" (less harsh than Crow).
