Tundra Bean-Goose
Anser serrirostris
Rather large, dark gray-brown goose with typically small orange patch on bill, and orange legs. In flight lacks contrasting pale forewing areas of Pink-footed Goose and Graylag Goose. Not always safely told in the field from Taiga Bean Goose, but Tundra averages a shorter and thicker bill, vs. the longer, more sloping bill of Taiga. Breeds on tundra and winters in farmland and wetlands, where it associates readily with other geese.

The length ranges from 68 to 90 cm (27–35 in), wingspan from 140 to 174 cm (55–69 in) and weight from 1.7–4 kg (3.7–8.8 lb). In the nominate subspecies, males average 3.2 kg (7.1 lb) and females average 2.84 kg (6.3 lb). The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange.<p>The upper wing-coverts are dark brown, as in the white-fronted goose (Anser albifrons) and the lesser white-fronted goose (A. erythropus), but differing from these in having narrow white fringes to the feathers.<p>The voice is a loud honking, higher pitched in the smaller subspecies.<p>The closely related pink-footed goose (A. brachyrhynchus) has the bill short, bright pink in the middle, and the feet also pink, the upper wing-coverts being nearly of the same bluish-grey as in the greylag goose.

其他鸟类

White-crested Tiger-Heron
Tigriornis leucolopha
A shy, stout heron that forages alone near water in dense lowland forest and mangroves. The tail is often hidden by the wings, giving these birds a very front-heavy appearance. The distinctive white crest is often hidden by the barred black-and-brown plumage covering most of the body. Call is a deep, far-carrying boom, as is typical of most large bitterns.

Orange-footed Megapode
Megapodius reinwardt
Large gray-brown bird with a pointed crest on its head and massive orange legs and feet. Resident on the floors of tropical rainforests. This species builds very large nest mounds (so large they almost look like earthworks). Also found in cosmopolitan parks and gardens. Note loud crowing call.

Channel-billed Toucan
Ramphastos vitellinus
Large toucan, widespread across South American lowlands. Mostly black with a dark bill (although some populations have a yellow ridge on top of the bill). Significant plumage variation across range: throat color varies from white to orange; bare skin around eye varies from blue to red. In the western part of its range, appearance is very similar to White-throated Toucan, but note voice: a grating croak, not a clear yelp. Singles, pairs, or small flocks are found in the forest canopy, often around fruiting trees. Named for the groove along the upper part of the bill, which is difficult to see in the field.
