Spot-backed Antwren

A medium-sized, black-bellied bustard with diagnostic white chevrons on a brown-and-black mottled back. The male has a brown-gray neck and slaty cap, and the female is plainer. The name is misleading, as the red crest is almost always hidden. It walks slowly and steadily in arid woodlands, where it is common but due to its camouflage often avoids detection. The song is a sequence of clicking “tic-tic” notes that are followed by a mournful piping “sweee-swee-sweee sweet” series that accelerates to a crescendo. The male indulges in an absurd display in which he flies nearly vertically into the sky and then folds his wings and somersaults down as if shot, only to unbelievably land on his feet. In flight the Red-crested Bustard’s all-black underwings differentiate it from Black-bellied Bustard, which has white windows in the underwing.

Unmistakable leaf-green bee-eater of lowland and foothill forests. Namesake “beard” actually goes from the crown all the way down to the belly. Sallies out from a perch at middle and upper levels of forest to snag flying insects. Despite its bright coloration, can often be surprisingly difficult to find; listen for its unique song, a series of descending frog-like croaks.

Powerful dark brown seabird, resembles a dark, heavily built immature gull. Note eye-catching white flashes in the primaries when in flight. Adults have distinct pale mottling on the upperparts, which serves to separate them from adults of the very similar South Polar Skua. Juveniles are more uniformly colored, with warm-colored and largely unmarked underparts; note bulkier build and more powerful flight than Pomarine Jaeger. Breeds locally on moorland of islands and coasts in northern Europe, where aggressive near nests. Otherwise lives at sea, but may be seen from shore during windy conditions during migration periods. Feeds by pirating gulls and other seabirds, also by scavenging at fishing boats.
