Channel-billed Cuckoo

Description:

The Channel-billed Cuckoo is the world's largest cuckoo, measuring between 58–66 cm (23–26 in) long and weighing between 550–930 g (19–33 oz). These birds are brood parasites; instead of raising their own young, they lay eggs in the nests of other birds. The host species varies depending on the location; the most commonly targeted hosts are ravens, currawongs, butcherbirds and Australian Magpies.

Habitat:

The Channel-billed Cuckoo is found in tall open forests, usually where host species occur. This one was spotted in the leafy northern suburbs of Sydney. They migrate to northern and eastern Australia from New Guinea and Indonesia between August and October each year, and leave Australia in February or March.

Notes:

I must say they are not a welcomed guest in your yard during nesting season. The young birds have a loud, monotonous squawk... and they keep it up constantly. As beautiful as they are, it's enough to drive you mad!
