Fanti Sawwing

Unusual dark greenbul with upright posture that does strongly resemble a honeyguide. Males have a white eye and females a dark one. Both sexes show a large white patch in the outer tail. Found in the upper portions of lowland forest. Usually in pairs or small groups. Most often detected by call: a slow series of mewing whistles. Similar to Sjöstedt's Greenbul, but has darker gray underparts, and male further distinguished by its pale eye. Distinguished from honeyguides by its different shape, especially the longer tail. Flight is direct, unlike undulating flight of a honeyguide.

Rare bird of stunted treeline forest in the high Andes of Ecuador and southern Colombia. Mostly gray with a chestnut belly; male has a black cap. Usually seen perched atop a tree or tall bush, and perhaps more likely to be encountered early in the morning on dry days. Call is a raspy, nasal “greh!”

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.
