Yellow-browed Toucanet
Aulacorhynchus huallagae
Small, green toucan found only in remote regions along the east slope of the Andes in northern Peru. Most of its cloud forest habitat is currently inaccessible without a serious expedition, so few birders have ever encountered this rare species. Plumage is mostly green with a red rump and tail tip, a white throat, anda blue breast-band. Distinguished from Blue-banded Toucanet by the yellow (not white) streak above the eye and the vertical white stripe at the base of the bill. Mostly black bill and blue breast-band help separate it from Southern Emerald-Toucanet and Chestnut-tipped Toucanet.

分布与栖息地
The yellow-browed toucanet has a very small documented range on the east slope of the northern Andes of Peru. It is known from only one location in southern Amazonas Department, two in San Martín Department, and one in northeastern La Libertad Department. It probably occurs between them and possibly further north and south as well, but because the area is roadless opportunities for discovery are limited. It inhabits humid montane forest between elevations of 2,000 and 2,600 m (6,600 and 8,500 ft).

行为
The yellow-browed toucanet forages mostly in the canopy. It is known to feed on fruit but details of its diet are lacking.<p>Essentially nothing is known about the yellow-browed toucanet's breeding biology. Its nesting season appears to span from October to February or March and it is assumed to nest in tree cavities like others of its genus.<p>The yellow-browed toucanet's typical call has been described as "a series of 20 to 30 frog-like krik notes" and also as "a series of harsh grunts: rehh rehh rehh...."

Madagascar Ibis
Lophotibis cristata
A rather fantastical forest-dwelling ibis with a colorful face, white wing, and rich brown body. Endemic to Madagascar, where it is most frequently encountered in eastern rainforest, though it also occurs locally in western deciduous forest. Roosts and nests in trees, and feeds on the forest floor. Extremely shy, and unless spooked will rapidly flee from disturbance on foot. Very loud and vocal, giving a long and agitated series of wheezy, whining notes. Calls most often at dawn and dusk and during the night.
Chinese Blackbird
Turdus mandarinus
Large dark thrush of open forests, gardens, and farms; one of the more common urban birds throughout much of its extensive range. Frequently seen on lawns and fields away from cover, pulling up worms and other invertebrates. Both sexes dark with orange bills, the male black overall, the female dark brown. Sings beautifully from exposed perches throughout the day, a series of loud melodic notes that varies between individuals. Often gives a shrill shriek or a series of “wuk” notes when alarmed or agitated.
Thick-billed Parrot
Rhynchopsitta pachyrhyncha
Very local, long-tailed, and social parrot of mountains in northwest Mexico. Feeds in pine and pine-oak forests. Nests colonially in groves of giant aspens, whose soft trunks allow nest cavities to be excavated. Usually found in flocks, of 10–100 birds, less often in scattered pairs; often located by its far-carrying, raucous laughing calls. No similar species in its range; note the red forehead and small red shoulder patches. In flight shows a broad yellow stripe under the wings.
