Appearance:

Large shearwater with distinct, marked, dark cap and white collar. Blotched belly and underwings. White upper tail-coverts forms a horseshoe mark, but note that Cory's Shearwater may show the same. Dark patch at side of neck. Bill dark. Flight action powerful, with alternating glides and rapid bursts of beats with stiff wings. Seldom soars.

Sound:

Calls at breeding ground a deep, soft, moaning "oooh-aahh" ("surprised or shocked old lady"). Tone fairly clear, and pitch rising and falling.

Appearance:

Small, stocky, white heron with short bill and neck. Heavy jowl. Plumage all white, except in breeding birds which show varying amount of buff on back, crown and chest. Bill usually yellow, but turns orange-red in breeding birds, and is dark in immatures. Legs pale greyish green, but darker in young birds. May be confused with both Little Egret and Squacco Heron in flight. Differs from Little Egret in leg color and shorter, thicker neck and bill. Told from Squacco Heron by unstreaked body/head, and smaller bill. Generally leaves a less elegant impression than other small herons.

Sound:

Usually silent away from breeding ground. In the colonies a chorus of various coarse sounds can be heard. Most distinct is a disyllabic "rick-rack". Other sounds includes short, guttural utterings, or drawn, harsh shrieks.
