This is the picture of Large-Tailed Nightjar (Caprimulgusmacrurus). I saw it in Mesirrokow forest of Manokwari. The birds are usually active at nights. They like to sit among tall grass near rivers.
In addition to watching the nightjar, we can also watch Sulphur Crested Cockatoo, Yellow-capped Pygmy Parrot, Blyth's Hornbill, Brahminy Kite, and a lot more.
