Bluish Flowerpiercer

Beautiful small babbler with a black head, bright silver ear, orange underparts, and a bright red wing patch. Travels in noisy flocks through hill and submontane forest, sometimes in single-species groups and occasionally with other species. Unfortunately a common target of the cage bird trade, and escapees are often seen outside of their native range; in some areas, such as Hong Kong, they have even established self-sustaining populations. Warbled song often given as birds move around in flocks.

A medium-sized shearwater with uniformly dark brown plumage and no contrasting markings. Flies more steadily than most shearwaters and usually flies low over the water. Large numbers nest on most of the Northwestern Hawaiian Islands. A few pairs nest on Moku Manu Islet off the eastern coast of Oahu. Often seen from boats in the Northwestern Hawaiian Islands, but rarely on the main islands and rarely from shore. The voice, usually heard only at breeding colonies, is a low moan.

With its long curved bill, this uncommon Sumatran mountain forest endemic is unique within its limited range. Forages alone or in pairs, often in dense undergrowth where it can be difficult to see; listen for its song, a well-spaced series of even, clipped whistles that sound like they should be coming from a small owl. If lucky enough to catch a glimpse, look for a streaky dark brown body, very short tail, and bright white throat.
