Pallid Cuckoo

About the Pallid Cuckoo

The pallid cuckoo (Heteroscenes pallidus) is a species of cuckoo in the family Cuculidae. It is the only species placed in the genus Heteroscenes. It is found in Australia, with some migration to the islands of Timor and Papua New Guinea. It is between 28 and 33 cm (11 and 13 in) in size, with distinctive markings such as a dark bill, a dark eye with a gold eye-ring and olive grey feet which differentiate it from other cuckoos. The pallid cuckoo is similar in appearance to the oriental cuckoo (Cuculus optatus), with barred immature pallid cuckoos being often mistaken for oriental cuckoos.

English ornithologist John Latham described the pallid cuckoo in 1801 as Columba pallida "pale pigeon". Sources differ in the genera placement of this species. It is commonly placed in Cuculus, but genetic evidence and its song support its placement in Cacomantis, with its closest relative the white-crowned cuckoo (Cacomantis leucolophus).

"Pallid cuckoo" has been designated the official name by the International Ornithological Committee (IOC). Other common names include unadorned cuckoo, semitone-bird, scale-bird, and brain-fever bird—from its monotonous repetitive call. Wikipedia →
