Campbell Islands Teal

Anas nesiotis

The smallest of the three endemic New Zealand teal species. Small, flightless dark brown duck. Males have green iridescence on head and dark chestnut-colored breast. Females are uniformly dark brown. Both sexes show bold white eye-ring. More secretive than the closely related Auckland Islands Teal; most often found on the shoreline foraging through piles of seaweed or rocks. Also can be found on peaty streams or in wetland pools with adequate cover from sedges and tussock. Confined to Campbell Islands other than an introduction on Codfish Island, where a small population remains. Males give a soft trill as an alarm or territorial call. Females give a growl and a rapid quack. Distinguished from other New Zealand endemic teal species by location and more prominent white eye-ring.

Elegant Crested-Tinamou

Elegant Crested-Tinamou

Eudromia elegans

Distinctive and striking tinamou, nearly endemic to Argentina, from northern Patagonia through the Monte desert region. Prefers open, rocky habitat. In the northern chaco replaced by similar Quebracho Crested-Tinamou. Often found by its three-part whistled song: a “twee-tyoo-too” similar to but less emphatic and more consistently pitched than Red-winged Tinamou.

Bar-tailed Godwit

Bar-tailed Godwit

Limosa lapponica

Gangly wader with a long bicolored bill. Breeding plumage is dark brick-red below (male) or pale orangey (female); nonbreeding plumage is overall gray-brown with white belly; compare to Black-tailed Godwit. In flight shows rather plain upperwings with only a faint whitish wing stripe; white rump and finely barred tail. Mainly coastal away from tundra breeding grounds. Often in flocks feeding on mudflats and in brackish coastal lagoons, roosting in adjacent freshwater habitats. Feeds by probing its long bill into the mud.

African Penguin

African Penguin

Spheniscus demersus

The only penguin regularly found within its range. A pudgy, flightless, black-and-white seabird with wings modified into flippers. Uncommon and declining, but still easily seen at well-known breeding colonies. It is extremely ungainly on land but is a supreme swimmer in the open ocean, where individuals dive down as far as 60 m in pursuit of small schooling fish. Juveniles are covered in flufflike down, and immatures have a white throat and frequently look scruffy as they molt. Call is a repeated, donkey-like braying: “haaaaaaahh, haaaaaaahh”.
