Black-breasted Boatbill

A small gray-brown swallow with pale white underparts. It has a gray-brown chin, throat, and upper breast and does not show any kind of breast band. Tail is short, square-ended or sometimes marginally forked. It is mainly found around slow-flowing rivers, lakes, wet grasslands, and other wetland habitats; mostly seen in the air but sometimes sitting on wires or on the ground or on cliffs while breeding.

Medium-sized woodpecker with bold black-and-white barring on back and a cream-colored belly. A patch of yellow on the lower belly can be difficult to see. Male has red crown and yellow nape. Female lacks red crown. Distinctive in range, but hybridizes with Red-crowned Woodpecker; hybrids best left unidentified. Found in open woodland, edges, and gardens.

Small black-and-white shearwater that flies with snappy wingbeats. Pay attention to its face pattern: typically quite dark and smudgy, with white curling up behind the cheek. Underwing is mostly white, sometimes with dark markings. Flies low to the water with quick wingbeats, almost recalling an alcid; occasionally arcs up high in strong wind. Prefers cooler ocean waters in the North and South Atlantic; rarely seen from land. Rare but seemingly increasing in the Pacific. Found singly or in small flocks, sometimes with other shearwaters. In Caribbean and western Atlantic, most similar to Sargasso Shearwater but shorter-tailed and darker-faced, with white under the tail.
