Oriental Cuckooshrike
Coracina javensis
A large gray cuckooshrike with a strong, hooked bill. Upperparts are mostly gray with black primaries; male darker than female. Rump and upper tail are paler than back, which is apparent in flight. Male has gray throat and upper breast becoming paler on the belly. Female generally has paler underparts with faint gray bars except from the lower belly to the tail. Both sexes have a dark patch from the bill to slightly behind the eye, giving a masked impression. Juvenile is brownish, heavily scaled with whitish-buff, and mottled on the underparts. Immature has broader white edges to wing feathers. Vocal. Call is a two-noted, rather nasal “gii-yaak,” uttered in flight as well as from a perch. Inhabits lightly wooded country, avoiding wet forests.

Crested Ibis
Nipponia nippon
A white, exotic-looking waterbird with a bright red face and raggedy crest. Adults are washed in gray during the breeding season. Most colorful in flight; underwings are tinged with soft orange. Inhabits paddy fields, wet meadows, and riversides, and breeds in nearby forests. Extremely restricted in range, the bulk of the wild population is restricted to a preserve in Yang’xian in China’s Shaanxi province, though reintroduction programs have been successful in Japan and other parts of China.

Little Bronze-Cuckoo
Chalcites minutillus
A small greenish bird with a heavily barred throat, chest and tail. Lacks the dark stripe through the eye seen in Horsfield's Bronze-Cuckoo. Males have a prominent red eyering. Usually observed in thicker vegetation, such as mangroves and wetter forest. Has a distinctive call - a fast series of around 5 descending staccato notes and trills.
