分布与栖息地
The chestnut-breasted coronet is found from extreme southeastern Colombia south along the east slope of the Andes through Ecuador and Peru as far as Cuzco Department. It also occurs on the west slope of the Andes from central Ecuador into northwestern Peru. It inhabits the interior and edges of humid montane forest and also gardens near the forest. In elevation it ranges between 1,600 and 3,300 m (5,200 and 10,800 ft) in Ecuador, though is most numerous between 1,900 and 2,700 m (6,200 and 8,900 ft). In Peru it occurs between 1,500 and 3,300 m (4,900 and 10,800 ft).

行为
The chestnut-breasted coronet's movements, if any, have not been documented.<p>The chestnut-breasted coronet is highly territorial and defends clusters of flowers from other nectar-feeding birds. It typically forages from the mid-story to the canopy. It feeds by clinging to the flower, holding its wings open for a second or two after landing. In addition to feeding on nectar it captures small insects by hawking from a perch.<p>The chestnut-breasted coronet's breeding phenology has not been described. It is assumed to make a cup nest like other closely related hummingbirds.<p>One description of chestnut-breasted coronet vocalizations is "a high, thin, liquid tip, a rapid, sweet trill, and various squeaky notes."

Chinese Barbet
Psilopogon faber
A brightly-colored inhabitant of tropical forest canopies. Slow moving and well camouflaged; its loud and far-carrying song, combined with its secrecy, ensure that it is usually heard far more often than seen. If seen well, combination of red-and-yellow throat, blue ear, black crown, and green body distinguish it from any other similarly sized birds in its range. Regularly visits fruiting trees.
Morrison's Fulvetta
Alcippe morrisonia
Active small songbird, endemic to Taiwan. Brown above, white below, with gray head, large white eyering, thin black borders in crown (hard to see at times), and buffy wash in flanks. Very social, often moving in large flocks, sometimes mixed with other species. Inhabits forested regions from the lowlands up into montane forests. Gives harsh, grating chipping and whirring notes while moving in flocks. Song is short but sweet: a melodious warble followed by a hoarse whistle.
Moustached Tinkerbird
Pogoniulus leucomystax
Small, olive-green tinkerbird. There are yellow patches on the wing and rump and a white slash on the face. Found in and around montane forest at middle and high elevations. Most often detected by voice: a chirpy series of “tek” notes, which varies from a fairly slow series of 3-4 notes to a long series of very fast notes. Very similar to Green Tinkerbird, but only overlaps slightly in range, and separated by the white facial mark.
