Plumed Whistling-Duck

A large and relatively colorful member of the pipit family with a black necklace, a yellow-orange throat, a yellow breast, and whitish sides with long streaks. The white corners of the dark tail are conspicuous during its weak, fluttering flight. Found in grassland with some bushes and trees. Similar to Yellow-throated Longclaw, though there is only minor overlap in range; orange-throated birds are easily identified, but some individuals have a yellow throat, and these can be separated by their paler and much more heavily streaked flanks. Brownish immatures can be confused with pipits, but are larger and more robust. Not very vocal, but gives a high-pitched whistle and a simple song of doubled phrases. 

A long-winged, black-and-white bird that is most often found far out at sea, coming to land only to breed on remote cliffs from November into May. Adults visit the nest sites only at night, when it is possible to hear this species vocalizing. The rather similar Bermuda Petrel lacks this species’ white collar and white rump. Black-capped Petrels also have a darker headed or “cowled” appearance than Bermuda Petrels. Calls at nesting areas include a drawn out “awwwww” that often grows louder towards the end and is usually given in series, sometimes with a squeaky hiccuplike terminal note that has an oddly donkey-like quality. Also gives a puppy-like yelp.

A stocky, short-tailed forest pigeon. Shows a diagnostic head pattern, with yellow forehead, green upper nape, and burgundy collar. Back, wings, and tail dark brown, with gray outer tail feathers. Underside grayish, with soft yellow wash on the breast. Juvenile browner, with rusty edges to feathers. Singles or pairs forage on the floor inside montane forest. Typically runs away rather than flying. Restricted to Sulawesi island, where no other similar species occur. Gives a deep hooting call, sometimes with a barely audible introductory note: “whooo-whooo” or “w-whooo-w-whooo.”
