Palau Ground Dove
Pampusana canifrons
A rotund, short-legged ground-dwelling dove that usually runs rather than flies when startled. Mostly brown with a pale whitish-gray chest and face. With good views, the pale cinnamon neck and head are distinctive. No similar species occur in its range. Gives a typical dove-like “whoo whoo” call that accelerates over around 15 notes.

其他鸟类
Pallid Cuckoo
Heteroscenes pallidus
Large pale cuckoo, which lacks the warmer tones of both Fan-tailed and Brush cuckoos. Yellow eyering, and a dark indistinct stripe across the cheek. Has a distinctive call that has several notes, and tends to perch in prominent places or fence-posts while calling.
Coral-billed Ground-Cuckoo
Carpococcyx renauldi
Elusive pheasant-like ground-dwelling bird, remarkably attractive when seen in good light: bluish gray above, pale gray below, with red bill and legs, pale eye surrounded by blue skin, dark hood and long tail that both show blue and violet tones. Forages on or close to the ground in dense cover of lowland and foothill forests, where it can be difficult to see despite its size. Male gives a haunting call, a long, sonorous whistle that rises at the middle and falls off toward the end.
Musk Duck
Biziura lobata
Large and chunky stiff-tailed diving duck with a heavy triangular bill. Floats very low in the water. Both sexes are dark grayish, but male has an obvious lobe of skin dangling from its chin. Usually observed on the water, regularly diving while feeding. Bill is much shorter and heavier than Blue-billed Duck.
