Barka Indigobird

Uncommon dark swiftlet. Endemic to a smattering of the Philippines islands, from Luzon to Mindanao to Palawan. Habitat can be helpful in identifying this confusing species; generally favors ridges and slopes in montane and submontane areas above 700-800 meters. Readily confused with significantly larger Ameline Swiftlet, but present species has a more squared-off-looking tail (fork is shallow and often unnoticeable), tends to fly lower and more erratically, and more often forms flocks. Combination of dark rump, unglossed dark back, and medium size separates this species from Gray-rumped Swiftlet, Pygmy Swiftlet, and Ridgetop Swiftlet. Frequently calls while in flight, giving a squeaky chattering twitter.

A small drongo with a dull-black back and a relatively short, distinctively forked tail. The “white-bellied” form has an extensively white belly diffusely demarcated from the dark gray throat and breast. The “white-vented” from is restricted to Sri Lanka and is darker overall, with dark gray underparts and a white vent. The species is similar to juvenile Black and Ashy Drongos, which are larger and have smaller amounts of white, diffused with a dusky color or scaling, on the belly and vent. White-bellied is found in dry and open forests across the Indian subcontinent.

Handsome, mostly silvery gray bird of tropical lowland forest and adjacent semi-open areas with taller trees. Usually found at mid-upper levels of fruiting trees, sometimes in small groups that mix readily with the commoner Masked Tityra. Black-crowned is told from slightly larger Masked by its solidly black bill. Male is more silvery overall, with a black cap; female had brown face and smaller black cap. Tityras nest in tree cavities, that they sometimes steal from woodpeckers.
