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