Sulawesi Myna

Common and widespread large gull found throughout North America. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Usually shows a dull pinkish base to the bill by the first winter, and develops a pale eye by the second winter. Some immature birds can fade to almost white, especially in their first or second summer, but they always show darker wingtips. Occurs inland and along the coast, frequenting fishing boats, beaches, lakes, and landfills. Often forms large flocks with other gulls.

Large elaenia with a striking headdress. It inhabits lightly-wooded areas, such as overgrown clearings, forest edge, and river islands, along the eastern base of the Andes. Mostly gray and olive with a yellow belly and white wingbars. Spiky white crest is frequently held erect, and is bordered by dark forehead tufts that can look like little horns. Usually found hawking insects from a conspicuous perch, and gives short, burry calls.

This gorgeous medium-sized heron is uncommon but widespread in lowlands of South America, barely extending into eastern Panama. Not likely to be mistaken: combination of silvery back, buffy neck and belly, black cap, and blue lores (sometimes radiant turquoise!) help distinguish this species from other herons. Also note the long white plumes on the back of the head. Occurs around swamps, forested ponds, and rivers, usually singly.
