Red-billed Curassow

Crax blumenbachii

Very large terrestrial species. Males are mostly black with a curly crest and a white belly and vent. Note the red bill knob with a small wattle. Females have black-and-chestnut bars on their wings and a rufous belly. Inhabits humid primary forests with dense understory where it normally forages in pair or small family groups.

Identification

The red-billed curassow is a large bird reaching a length of 82 to 92 centimetres (32 to 36 in). The male has pure black upper parts with a large black crest, and white underparts. There are bright red wattles and knobs at the base of the bill. The male can be distinguished from the wattled curassow (Crax globulosa) by being less bluish-black and from the black curassow (Crax alector) by being less purplish-black. The female lacks the wattles and has black upper parts, a black and white barred crest, reddish-brown wings barred and mottled with black, and reddish-brown or ochre underparts.

Behavior

The red-billed curassow is a largely ground-dwelling bird. It feeds on seeds, fruits, buds and small invertebrates. Males can be heard issuing their loud "booms" in September and October. Females lay a clutch of one to four eggs and the young are fledged by the end of the year.

Bearded Barbet

Bearded Barbet

Pogonornis dubius

Large, colorful barbet with a huge ivory-colored bill. Note the red underparts with a thick black bar across the middle. Found in a variety of habitats, including moist and dry savanna, woodland, gardens, and secondary growth, often in the vicinity of figs and other fruiting trees. Most often in pairs or small groups. The call is a very rough, explosive “rwauk,” often given in a slow series. Similar to Double-toothed Barbet, but separated by the black chest band and the lack of a red bar on the shoulder. 

Subantarctic Snipe

Subantarctic Snipe

Coenocorypha aucklandica

Small brown- and black-mottled wader with a long, slightly downcurved bill. The only snipe species known to occupy the Auckland, Campbell, and Antipodes Islands, with slight variations in size and markings between the three island subspecies. Prefers dense vegetation during the daytime. Male call often heard at dawn and dusk. Call is a “trerk trerk trerk” occasionally building to a “queeyoo queeyoo.” The Maori name (Hakawai) is given to their nocturnal aerial flight display, which includes a roaring sound of air vibrating through their spread tail feathers. Distinguished from possible vagrant Latham’s Snipe by smaller size and shorter wings and legs.

Variable Sunbird

Variable Sunbird

Cinnyris venustus

Medium-sized sunbird with strikingly different breeding male and female plumages. Breeding males are green on the head and back, with a purple band across the breast. There is much regional variation; the belly can be yellow-orange, yellow, or white, though it is yellow across most of the range. Some subspecies also show extensive purple onto the throat. Females and non-breeding males are plain olive-brown on the back and dull yellow below. Found in a broad range of habitats, from arid thornscrub to moist savanna, gardens, and forest edge. Vocalizations typical of a sunbird, and include a quick jumbled song. Similar to Collared Sunbird, but larger, with a longer and more curved bill.
