New Caledonian Imperial-Pigeon

Large, dark, long-tailed forest nightjar. Males have small white patches in the outer wings and at the corners of the tail; females have all-dark wings and can show small buff tail corners. Found in lowland rainforest, including forest edge and clearings. The distinctive vocalization is usually given from a tree: a single barking “kow,” followed after a pause by a quick series of several similar notes. Found in the same habitat as Brown Nightjar, but larger and longer-tailed; males further distinguished by the pale patches in the wing and tail. 

Small, dark, chunky heron. There are rufous patches on the wing and belly; this can be hard to see when perched but is conspicuous in flight. Found in thickly vegetated wetlands, ranging from flooded grasslands to swamps. Usually solitary. Fairly shy but will sometimes stand in the open. Shares dark coloration with Black Heron, but has chestnut patches, all-yellow legs, and a yellow base to the bill.

Fairly common sea duck; feeds by diving. Breeds on tundra lakes; winters at sea in coastal bays, estuaries, harbors. Rarely seen inland on fresh water, mainly during migration periods. Occurs locally in flocks of hundreds, but also found as singles and small groups. Male distinctive: wholly black with raised knob at base of bill, yellow wedge on top of bill. Female dark brown overall with pale cheeks. In flight looks all-dark, often flying in rather tight groups low to fairly high over the sea.
