Stripe-throated Yuhina

Chocolate-brown thrush with finely scaled white underparts. Very similar to Himalayan and Sichuan Thrushes, with which it was once considered a single species. Alpine is shorter-billed than the other two species, with a darker brown forehead than Sichuan Thrush; averages longer-legged and longer-winged than Himalayan Thrush. Long-tailed Thrush can also be similar, but lacks Alpine’s intense throat and chest speckling, and has thin but prominent pale wingbars. Alpine Thrush breeds in open rocky alpine areas with scattered shrubbery between 3000 and 4500 meters of elevation, though it descends lower into the foothills during winter. Song is simple but not altogether unmusical, consisting of fluid warbling notes and squeaky grating ones. 

A large seedeater with a very thick pinkish bill. Brownish-olive above and yellow below with streaking along the sides. Males are slightly brighter and have thicker streaking below. Both sexes have a yellow rump that is conspicuous in flight. Found in dry thorn savanna and thorn scrub, usually in pairs or small groups. Similar to Brimstone Canary, but distinguished by the notably larger bill, streaked underparts, and yellow rump. The song is twittering, high-pitched, and variable, and can include imitations of other species. The most common call is a sliding “sreeyu.” 

Huge white bird with long neck, reddish-orange bill, and black face. Adults have a black knob on top of the bill. Immatures are dusky brown with a gray bill. Native to northern Europe and Asia, but introduced in many regions, where it is now common on ponds, lakes, and calm coastal waters. Very aggressive toward native waterfowl. Often seen in pairs or small family groups.
