Western Boubou

A small, long-billed, long-tailed bird of dense tangled undergrowth in lowland forest. Has olive-green wings, back, and tail, a pale belly, a gray head and chest with streaks, a rufous forehead and mask, and orange legs. Similar in habits and shape to White-browed Tailorbird, but lacks the black head and white brow. Also similar to Phillipine Leaf-Warbler, but has a longer bill and usually cocks its tail. Song is an accelerating series of slightly rising notes ending in a staccato trill.

Small flycatcher, extremely similar to several other species. Generally shy and inconspicuous; breeds in spruce forests often near boggy areas. Migrants tend to be found in denser wet areas within woods. Olive-greenish above with distinctive yellow wash on throat and belly. Black wings with bold white wingbars. Nearly identical to Western Flycatchers, but limited range overlap. Within range, main confusion species is Least Flycatcher. Bright yellow throat and belly is usually enough to identify Yellow-bellied Flycatcher, but some worn birds can be very similar. Song is similar to Least Flycatcher ("chebek") but more slurred, with a soft buzzy tone. Not frequently repeated like Least Flycatcher. Soft whistled call note, "pwee," unlike Least's sharp "whit" call.

Striking large shearwater with distinctive dark "M" pattern on upperwings. Also note crisp dark cap and clean white underwings and belly. Looks silvery-gray above when fresh, but worn birds can be more brownish. Graceful flight style. Usually easily separated from other shearwaters by wing pattern. Breeds on islands off New Zealand; ranges across the Pacific during nonbreeding season; uncommon off the west coast of the U.S. in fall. Rarely seen from land, prefers to stay offshore. Found singly or in flocks with other shearwaters.
