ハシブトゴイ Nycticorax caledonicus

Stocky heron that roosts in groups in tall trees, usually beside water (including mangroves). Adult is rufous with pale breast and a black cap. Immature is heavy streaked, and can be easily confused with Striated Heron (black crown), Black Bittern (darker, with yellow neck stripe), or Australasian Bittern (which is a much larger bird).
