New Zealand Scaup

Aythya novaeseelandiae

New Zealand endemic diving duck. Widely but patchily distributed throughout North and South Islands; not found on Stewart Island, and no longer present on Chatham Islands. Unlike any other resident duck species. Compact and dark; floats on water with cork-like buoyancy, showing bath-toy duck silhouette. Forms large flocks, often congregating in sheltered areas near willows or reed beds. Spends a lot of time underwater, where it can travel considerable distances. Sexes alike but distinguishable. Male has dark black plumage, iridescent blue-green head and wings, and yellow iris. Female is duller brown with brown iris. Flies with very fast wingbeats, often just above the water’s surface. Vagrant Hardhead differs in its white iris, white undertail, and white “saddle” on bill.

Greater Bluebonnet

Greater Bluebonnet

Northiella haematogaster

Brown parrot with yellow-and-red belly and deep blue face, typically found in dry inland habitats in eastern Australia. Multiple subspecies vary in the color of their wing patch, belly, and undertail. Usually seen in small groups, this species is often hard to approach and is easily flushed. In flight, the blue wings and red shoulders contrast with pale brown back. Distinguished from the similar but smaller Naretha Bluebonnet by presence of red on belly.

Long-tailed Fantail

Long-tailed Fantail

Rhipidura opistherythra

A small brown songbird with a long tail, often held cocked or fanned. Upperparts largely rufous except for a grayer head with a pale brow. Shows a white throat and uniform buff underparts. Inhabits lowland forest and sometimes mangroves. Confined to the Tanimbar Islands. Told from Arafura Fantail by the lack of a white tip to the tail and the absence of a black breast patch. Gives a distinctive, repetitive, see-sawing two-note song phrase, “wee-oo-wee-oo-wee-oo,” rising on the first note, falling on the second. Also gives nasal jittering calls.

Micronesian Rufous Fantail

Micronesian Rufous Fantail

Rhipidura versicolor

Small, active songbird with long, pale-tipped tail and warm brownish-orange on the forehead, rump, and tail base. Grayish brown above and pale below overall, with a white throat and black-speckled breast. Frequently cocks and fans tail. Endemic to the Mariana Islands (Saipan, Tinian, Agiguan, and Rota) and Yap, in the Carolina Islands. Extinct on Guam. Inhabits a wide range of habitats, from remnant native forests to towns. High-pitched, tinkling song often has a descending quality. Formerly grouped with other closely related species under “Rufous Fantail.”
