Gray-backed Fiscal
Lanius excubitoroides
Large, long-tailed gray, black, and white shrike. The male has completely white underparts, while the female can show a small rufous flank patch. Large white patches at the base of the tail are conspicuous in flight. In the eastern part of the range, found in woodland, savanna, and cultivation. In the west, found only in arid thorn savanna. Always in small and conspicuous groups. The vocalization is given in chorus by a group: a fast, jangling mixture of slurred calls. Distinguished from other black-masked, gray-backed shrikes by the black line connecting the black wing and black face-mask, and by the large white patches in the base of the tail.

行为
The grey-backed fiscal is a sociable bird and is often found in wooded grassland, gardens and damp acacia scrub. It is often seen in pairs or small groups on tree stumps, wires and branches, engaged in wing fluttering, tail waving and noisy babble. It is a gregarious, cooperative breeder. Nests are built up to 10 m (33 ft) off the ground, near the trunk of the tree or on peripheral branches. The female builds the nest while the male may bring nesting materials and food for the female. A clutch of about four eggs is laid. Incubation is by the female and lasts about fourteen days, with the young remaining in the nest for a further twenty days.

Monk Parakeet
Myiopsitta monachus
Medium-sized parakeet, bright lime green above with whitish face and chest, pinkish bill, and blue wingtips. Native to South America, where it is found in various open habitats, especially rural agricultural areas and towns. In introduced range, can be found locally in large cities. Builds enormous stick nests, often on large structures like cell phone towers and power poles; "Cliff Parakeet" of arid southcentral Bolivia manages to build, quite impressively, on sheer cliffs. Listen for its harsh, screeching voice.
Green-cheeked Parakeet
Pyrrhura molinae
Long-tailed parakeet with a brown crown and green cheeks; depending on the subspecies, the breast is either white or yellow, and the maroon belly patch is often reduced. Found in woodland and gallery forest; usually seen foraging or flying in noisy groups.
Kashmir Nutcracker

A jay-like bird with a long pointed bill, a black cap, and white spots all over. Very similar to Eurasian Nutcracker, but the Kashmir Nutcracker appears whiter overall with more white on the back, underparts, undertail, and tail tips. Forages in conifers for nuts and seeds, occasionally descending to the ground. Calls include loud, harsh “kraaa” notes.
