Eastern Red-rumped Swallow
Cecropis daurica
Brightly-colored swallow with a deeply forked tail, pale orangish rump, black squared-off undertail coverts, and an incomplete orange collar. The underparts are always streaked, though there is geographical variation, with streaks ranging from fine and sparse to thick and heavy. Juveniles average paler and lack extensive orangish tones; may resemble house-martins but note deeply forked tail. Builds mud nests on mountains, cliffs, and on human structures. Forages over open areas. Frequently gives a short, sparrow-like “twi’wit.” Usually separated from European Red-rumped Swallow by range, but in case of any overlap, should be separated by evenly cinnamon rump (vs. bicolored), dark lores, dark stripe on nape, and bolder streaking on underparts.

Olive-flanked Robin-Chat
Dessonornis anomalus
Dark, compact robin-chat with the least orange of any member of this group. There is considerable geographical variation, but always shows a pale eyebrow and throat, and some rufous on the belly, flanks, rump, and tail. The color of the underparts varies from blackish to white to buff, and the color of the upperparts from black to gray to brown. Some populations show a strongly black-and-orange tail, while others have a tail that is completely rufous. Found in the understory of montane forest. Generally uncommon and skulking. The variable song consists of a mournful, descending series of whistles.

Northern Hawk Owl
Surnia ulula
Unique medium-sized owl of the boreal forest. Remarkably long-tailed for an owl; reminiscent of a small hawk in flight with quick, snappy wingbeats. Pale eyes give it an angry look. Brownish overall with white spotting above, barred underparts, and spotted crown. Feeds on small rodents by sight and sound. Often seen perched on the very top of a spruce tree or snag, surveying the surrounding landscape for prey. When rodent populations crash, large numbers of Northern Hawk Owls can move south of their normal range.

Violet-backed Starling
Cinnyricinclus leucogaster
A small starling with dramatically different-looking sexes, although both sexes sport a distinctive dark bill and a lemon-yellow eye. The male is iridescent, ranging from plum-violet to purple-blue depending on the light, except for the white belly and vent. The female and juvenile have brown-streaked white bellies and darker brown-streaked upperparts. Pairs and small flocks occupy open woodland, riverine forest, and wooded parkland, where they feed on fruit and berries, being an important dispersal agent of mistletoes, although they also opportunistically take insects, particularly winged termites and ants. Some populations are resident, but most are migratory or nomadic.
