Pink-eared Duck
Malacorhynchus membranaceus
A distinctive species with fine zebra-striped plumage and a long and shovel-shaped bill giving a fang-like appearance. Typically feeds by swimming in tight circles. Like many waterbirds in inland Australia, it moves around a lot, and can be found in very large numbers when conditions are right.
分类信息
The pink-eared duck was first described by the English ornithologist John Latham in 1801 under the binomial name Anas membranacea. It is the only living member of the genus Malacorhynchus; a closely related, but slightly larger extinct form from New Zealand was described as Scarlett's duck (Malacorhynchus scarletti). This peculiar duck may be most closely related to the shelducks but its relationships are enigmatic. It may be closer to the musk duck and the stiff-tails (Sraml et al. 1996) and, formerly placed in the paraphyletic "perching ducks"; it is in any case not close to the dabbling ducks.<p>This species is the only member of the order Anseriformes known to have carotenoid pigments in its feathers, in the characteristic pink "ear" spot.<p>The pink-eared duck was reportedly known as the New Holland duck by early colonists in Western Australia.

Natewa Silktail
Lamprolia klinesmithi
Small and stub-tailed, appearing mostly dark. Shows vivid electric blue speckling on chest, back, and head, brilliant blue in direct light. Shocking pure white rump and upper tail are diagnostic and obvious. Reliant on primary forest. Voice mostly unknown, but quiet raspy short notes reported.
Three-banded Courser
Rhinoptilus cinctus
Elegant, cryptic, long-legged, upland shorebird. Shows a dark upperwing and a largely white underwing in flight. Found in savanna and woodland, including some miombo. Nocturnal species that spends the day roosting under a thick bush. Calls at night with a repeated metallic “chik.” Somewhat similar to Double-banded Courser but is nocturnal and has a more complex and striped head and chest pattern.
Ash-throated Antwren
Herpsilochmus parkeri
Rare antwren restricted to a small area of the eastern Andes in northern Peru. Note the black cap, striped face, white wingbars, and lack of rufous in the wing. Female has a buffy tinge on her face and throat. While several other antwrens in Peru share similar plumage features, none of them occur in the limited range of this species. Inhabits the canopy of stunted cloud forest, especially on ridgetops. Song starts with a few rising notes and ends with a descending trill.
