Yucatan Wren

A typical uniformly grayish-brown petrel with pale mottling at the base of the bill that gives it a somewhat “frosted” facial appearance. Pale bar along the leading edge of the underwing between the body and elbow is evident in flight. Highly pelagic, visiting land only to nest. Similar to Kermadec Petrel, but lacks the white primary shafts in the upperwing of that species and is overall more uniformly colored. Providence Petrel is similar but appears much heavier-chested and paler-faced, with more extensively mottled gray-brown tones across the body. Herald Petrel is very similar, but has much more contrasting dark-and-light underwing pattern. Henderson Petrel is silent at sea.

This red-eyed masked-weaver has a plain olive-green back and pink-brown legs. The breeding male has a black face mask, with the black band on the forehead above the bill varying from broad in the south to narrow farther north. Female and juvenile are dull and inseparable from other masked-weavers. Pairs and colonies are localized residents of reedbeds, wetlands and adjacent woodland, in a narrow global range between northeastern Zambia and southeastern DRC. The breeding males of Katanga and Southern masked-weavers are very similar, but the former are smaller, have some saffron around the masks, and have darker green backs and rumps; breeding male Tanganyika and Lake Lufira Masked-Weavers have more burnt-orange around the face and underparts, and ranges do not overlap.

Brown parrot with yellow-and-red belly and deep blue face, typically found in dry inland habitats in eastern Australia. Multiple subspecies vary in the color of their wing patch, belly, and undertail. Usually seen in small groups, this species is often hard to approach and is easily flushed. In flight, the blue wings and red shoulders contrast with pale brown back. Distinguished from the similar but smaller Naretha Bluebonnet by presence of red on belly.
