Elliot's Storm-Petrel

A typical Old World cuckoo, with gray-and-white plumage and long wings and tail. A brood parasite that lays its eggs in the nests of many other bird species. Breeds throughout Madagascar in virtually all habitats with woody vegetation. Extremely vocal when breeding during the rainy season, giving a distinctive “do-do-ka-foo” song day and night. Easily identified on Madagascar, where it is the only regularly occurring cuckoo. Elsewhere, extremely similar to Lesser Cuckoo. Many individuals probably indistinguishable, though Madagascar Cuckoo has either weak barring or no barring on the undertail, whereas Lesser Cuckoo always shows strong barring. Similar to Common and African Cuckoos, but smaller, with a much blacker tail and rump. 

A distinctive crow with a strikingly long bill, noticeable even in flight. Adults have purple-glossed blackish plumage and a prominent pale eye. Juveniles are dark-eyed and lack gloss. Occurs in the canopy of any areas with trees, where it is typically seen in small, active, vociferous groups. Restricted to the north Moluccas. Noticeably longer-billed than local Torresian Crows. Gives high-pitched “krak-krak-krak” calls repeatedly and often.

Large seabird of offshore tropical waters around the globe; not seen from the mainland. Adult plumage is variable, but all have bright red feet and colorful bill and face; some have wholly brown plumage, others are white with a black trailing edge to the wings; the tail can be black or white. Immatures of all types are brown overall with dull pinkish feet. Looks smaller and more slender than other boobies, with more crooked wings. Nests on offshore islands (usually in trees and bushes, unlike other boobies, which nest on the ground).
