Yellow-vented Eremomela

Large, stocky shorebird with a distinctive black-and-white wing pattern. Larger than Greater Yellowlegs, smaller than godwits. Overall grayish, with messy dark patterning in breeding plumage. Bill is straight and rather thick, with a paler base. Legs are grayish. Two distinct subspecies. “Eastern” Willet is smaller, darker, browner, shorter-billed, shorter-legged, and strictly coastal. Breeds in saltmarshes from Atlantic Canada to the Gulf of Mexico; migrates early, mostly departing the U.S. in August, and winters almost exclusively on the northern coast of South America. Especially likely to be seen foraging on extensive mudflats, sometimes in flocks. “Western” Willet is larger, paler, grayer, longer-billed, and longer-legged, giving it a more godwitlike appearance. Breeds in marshy grasslands in the Interior West; winters much further north than “Eastern” Willet, from both coasts of the U.S. to as far south as Chile. Especially likely to be seen on beaches.

Rather plain medium-sized warbler: warm brown above with narrow pale spectacles, pale buffy below. Can be very difficult to separate from other reed warbler species. Most populations breed in reed or sedge beds, both pure and mixed with bushes, often wandering to adjacent scrub and thickets. “Mangrove” Reed Warbler is a resident in mangroves along the Red Sea. Non-breeding migratory birds may wind up in a wide range of habitats, from marshes to mangroves, to acacia scrub and cultivation. Often heard but can be hard to see: prolonged song much like Sedge Warbler but more even-paced and melodic, without rough and jerky phrases. Calls include a low “chuk” and rattled “chrrt.”

Large sparrowlike bird; entirely olive with contrasting gray head and black face. Range does not overlap with other similar-looking sparrows and brushfinches. Often found in pairs or small family groups, usually scratching through leaf litter or low in a tangle in the forest understory. Loud song often heard at dawn. Sexes alike.
