Red-knobbed Imperial-Pigeon

Small finch with bright orange bill and a distinctive black-and-white “moustache” mark. Adult male gray above, with barred grayish bib, rusty white-spotted flanks, and black-and-white tail pattern. Female smooth gray to buff on the chest and belly; juvenile similar but with a dark gray bill. Inhabits arid inland Australia, where often found in very large flocks.

Gangly wader with a long bicolored bill. Breeding plumage is dark brick-red below (male) or pale orangey (female); nonbreeding plumage is overall gray-brown with white belly; compare to Black-tailed Godwit. In flight shows rather plain upperwings with only a faint whitish wing stripe; white rump and finely barred tail. Mainly coastal away from tundra breeding grounds. Often in flocks feeding on mudflats and in brackish coastal lagoons, roosting in adjacent freshwater habitats. Feeds by probing its long bill into the mud.

Overall rusty-colored, medium-sized flycatcher of humid tropical forest in the lowlands. Favors middle to upper levels inside forest, where sits still for long periods and sallies out for insects and other small critters. Call is a distinctive slow wolf-whistle—“whee-wheeu,” given at infrequent intervals and easily imitated. Note the overall rusty plumage, slender bill, and behavior. Can be confused with slightly larger Rufous Piha, which has a bushier face, paler throat, and a very different voice.
