Dark Batis

Well-named, the common roadside hawk in tropical lowlands of East Mexico and Central and South America. Often seen on wires, phone poles, posts out in fields. Adult has staring pale eyes, streaked breast contrasting with barred belly. Immature streaked below, much like many other immature hawks, but its tail has broad and fairly even bands. Flies with rather quick, stiff wingbeats, recalling a Red-shouldered Hawk or an Accipiter; noisy flight display mainly in late winter-spring.

A boldly patterned large and chunky shorebird of southern South America and Falklands. Favors rocky coastlines and adjacent river mouths, but also frequent on nearby grasslands and lakeshores. Associates readily with other oystercatchers. Told from American Oystercatcher by its glossy black head and upperparts that lack the white shoulder spur. In flight the distinctive upperwing pattern with big white panel on trailing edge separates it from American. At close range, also note the yellow eyering (red on American). Voice is also very distinct from other oystercatchers.

A sparrow-like weaver. Red-hooded breeding males are distinctive, but females and non-breeding males are drab. A Comoros endemic that is found in and adjacent to humid forest on the western three islands, and in drier, scrubby lowland habitats on Mayotte. Plumage varies across the different islands. The most distinctive birds, on Grand Comoro, have much less red on the breast than other populations. Can be very similar to Red Fody. Breeding male Red-headed Fody lacks red on the back and belly, though molting male Red Fody can match this pattern. Females and non-breeding males very similar to Red Fody, but Red-headed Fody is larger, darker, and more greenish, with a longer, slightly curved bill. Also similar to female House Sparrow, but distinguished by the more olive-green coloration and the longer bill. Calls are high, silvery notes, given in long series as a song.
