Golden-browed Chat-Tyrant

Largest tern in the world; widespread but typically uncommon. Thick, bright-red bill is distinctive; most have small dark marking near the tip. Note solid black cap in summer which turns to black streaks in winter. Juveniles have V-shaped markings on the upperparts. Feeds by cruising over lakes, rivers, estuaries, and reservoirs looking for fish, then plunging to catch them. Smooth wingbeats, more gull-like than choppy flight of small-bodied terns. Very vocal, giving loud raucous screams. Compare especially with Royal Tern, which is slightly smaller and more slender, and has a thinner, more orangey bill.

Small green toucan of humid montane forest. Blue chest band is distinctive but can be difficult to see; notice also the bluish coloration in its face and bill and the yellowish bill tip. Forages singly or in pairs through the short canopy of high elevation forest, occasionally associating with mixed-species flocks, especially with other larger birds like barbets and foliage-gleaners. Listen for an even-paced series of low, grating “grrok” notes.

A medium-sized greenbul of the mountains of Cameroon and southeastern Nigeria. Remarkably uniform yellow-olive in plumage, with a red eye. Found in montane forest, secondary habitat, and scrub. Feeds in the understory and at middle levels of the forest. Somewhat similar to Western Mountain Greenbul, but easily separated by the lack of a gray head and contrasting white eye crescents. Might be confused with Cameroon Olive-Greenbul, but separated by brighter coloration overall and an olive-green rather than reddish-brown tail. The song is a chirpy series of nasal notes that ends with an accelerating flourish.
