Large cuckoo known for its loud distinctive calls. Bright red eye. Males entirely black. Females barred with varying patterns, a black crown and a strong moustache. Occurs in a variety of habitats, fairly common in suburban areas. Strong migrant, spending the middle of the year in eastern Indonesia, New Guinea and the Solomon Islands, and migrating south into eastern Australia during the austral summer. Calls are very loud, often heard at night or pre-dawn, including a piercing ‘coo-eee’, and a longer ‘wirra-wirra-wirra’ (similar to a car alarm).
