Rufous-winged Cisticola

Slender-billed, glossy black bird of humid forest, woodland, thickets, and overgrown clearings; shape and habits like Gray Catbird of North America. Common on Cozumel Island, but generally uncommon to rare on the Yucatan mainland. Often sings from a prominent perch, but otherwise rather retiring and easily overlooked, mainly at low levels in bushes; also hops on the ground, flipping and fanning its tail. Told from other black songbirds in its geographic range by habits and slender bill.

Stout heron with flashing white wings; can be mistaken for a egret in flight, but note darker head in all plumages. Handsome in breeding plumage, with creamy head, dark red breast, and lacy black plumes on the back. Streaky brown nonbreeding plumage is nearly indistinguishable from other pond-herons. Forages in rice paddies, pond and lake edges, and mangroves.

A large heavily built duck that is uncommon to fairly common along rocky seacoasts; not found on lakes, unlike Flying Steamer-Duck. Both sexes are steely blue-gray overall, brighter than Flying Steamer-Duck, with a stouter and deeper-based bill. The bill of both male and female is bright orange in the southern parts of its range, but is orange with a greenish distal patch around Chiloé Island (likely a different species). The bill of juvenile birds is duller grayish to dull yellowish; attains adult color by winter.
