Iris Lorikeet

Iris Lorikeet

Trichoglossus iris

A small green parrot with a red forehead, an orange bill, a dark purple eye patch and crown, and a yellow collar. Juveniles show a brown bill. Found in small groups, mainly in the foothills, in forest and a variety of wooded areas. Confined to Wetar and Timor, where it overlaps with the larger and longer-tailed Marigold and Olive-headed Lorikeets. Iris Lorikeet shows a red forehead and pale throat, lacking the dark-hooded appearance of those lorikeets. Gives high-pitched screeches, “eeek,” similar to other lorikeets, but less harsh.

Common Nighthawk

Common Nighthawk

Chordeiles minor

Camouflaged to blend into daytime roosts. Intricately patterned with gray and brown. Often roosts along tree branches or on the ground. Feeds at night on large insects. Watch for them flying under bright lights at ballgames or supermarkets. Distinctive fluttering flight style, with wings usually held in a V-shape between bursts of flaps and maneuvers to snatch insects. Very similar to Lesser and Antillean Nighthawks; note voice and location of white wing patch close to base of primaries.

White-browed Shama

White-browed Shama

Copsychus luzoniensis

A medium-sized, long-tailed bird of lowland and foothill forest. Male has a black head, upperparts and chest, a single white wingbar, a white belly, pale orange sides, and white outer tail feathers. The female has a gray chest and face with a brown cheek, crown, back, and wings. Somewhat similar to Philippine Magpie-Robin, but White-browed Shama has a long white eyebrow and a rufous rump. Heard more often than seen. Song is a pleasant and varied whistled melody, often finishing in a low, descending warbling trill.
