Sulawesi Hawk-Eagle
Nisaetus lanceolatus
Adult shows a dark brown crested head, a white throat with central streak, a rufous breast with bold streaking, a densely barred belly, and feathered thighs. In flight, note densely barred body and forewings, sparse bars on outer wing, and evenly barred tail. Immatures show white on head and underparts and dark brown above, with narrower tail bars. Wings broad, with bulging inner wing. Found in tall forest from lowlands to mountains. More heavily built, larger-headed, and larger-billed than Sulawesi Honey-Buzzard, and also has feathered thighs and more evenly spaced tail bars. Immature resembles young Rufous-bellied Eagle, but hawk-eagle lacks dark flanks and mask. Gives a loud “ke-ke-ke-ke…” call.
识别特征
The Sulawesi hawk-eagle (Nisaetus lanceolatus) (earlier placed under Spizaetus), also known as Celebes hawk-eagle, is a medium-sized, approximately 64 cm (25 in) long, crestless brown raptor in the family Accipitridae. The adults have rufous-brown, boldly marked head and chest feathers, dark brown wings and black-barred white below. The young has white head and underparts. An Indonesian endemic, the Sulawesi hawk-eagle is distributed in rainforests of Sulawesi and its satellite islands of Buton, Muna, Banggai and Sula Islands.

Widespread throughout its habitat range, the Sulawesi hawk-eagle is evaluated as Least Concern on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES.

Derbyan Parakeet
Psittacula derbiana
Magnificent green parakeet with a black throat and a purplish breast and belly. Males have a glowing red bill while females have an all-dark one. Overall coloration quite similar to that of Red-breasted Parakeet, which has a pinkish breast instead of a purple one, but ranges do not overlap. Inhabits foothill and montane moist forests, where it forages in large, raucous flocks. Prefers pine woods. Declining due to extensive capture for the cage bird trade.

Vigors's Sunbird
Aethopyga vigorsii
This medium-sized sunbird of the Western Ghats is similar in appearance to Crimson Sunbird, but the two ranges do not overlap. Male is bright red with a gray belly and iridescent blue-green tail and head markings. Female is dull gray overall with a paler belly. Young males are similarly dull, but often have dull red patches, particularly on the breast. Forages actively in small flocks in upper levels of foothill forest and forest edge. Squeaky song and high “seep” calls comparable to Crimson Sunbird.

Eurasian Jackdaw
Coloeus monedula
Distinctive, small social crow with contrasting, silvery-gray neck shawl and staring whitish eyes; juvenile has duller shawl and eyes. Walks confidently, and can be easy to see where not persecuted; associates readily with crows and Rooks. Flocks can number in the hundreds or thousands in the nonbreeding season. Inhabits open and semiopen habitats, from towns and wooded parkland to farmland and sea cliffs; often around stone buildings and chimneys. Nests in cavities. Listen for its distinctive high-pitched “tchaw, tchaw” calls.
