Green-backed Gerygone

Slender, dusty-colored babbler with a long tail. Look for its contrasting white throat and streaked crown and back. Found in dry open areas such as semidesert, scrubland, and various edge habitats. Rummages about on the ground in mid-sized to large flocks. Gives a clear, musical, purring series of notes, either ascending or descending, as well as harsher, scratchier calls.

Small oceanic gull with stunning wing pattern. All ages show distinctive black outer wing, white inner wing, and dark back. Breeding adults have a dark gray head and black bill with yellow tip. Nonbreeding adults have similar distinctive bill but with a mostly white face. Young birds are browner above than adults, with a crisp scaly pattern on the back. Breeds on Arctic tundra. Often seen in flocks during migration and winter, generally far offshore. Rarely seen from shore, but occasionally shows up at large inland bodies of water.

Tea-green bulbul with a dark gray head and a spiffy erect crest. Black-crested Bulbul is structurally somewhat similar but is darker green with an all-black head and pale eyes. Crested Finchbill inhabits middle to upper-elevation forests and edges, where it often gathers in very large flocks. Bold and approachable; can often be found in field edges, parks, and gardens. Gives distinctively bubbly ascending trills, often in distinct phrases.
