Rufous-lored Tyrannulet

A pallid, medium-small, compact lark with a pale stout bill that appears swollen and a streaky crest that is often raised. The upperparts are sandy brown with indistinct dark streaks, the face is plain with a distinct eyebrow, and the breast shows very diffuse streaking on whitish underparts. Highly nomadic; small to very large flocks can appear after rains, sometimes associating with sparrow-larks or buntings, preferring arid grasslands on plains and gravel rather than sandy substrates. The species performs an aerial display with trills, whistles, and chirps. Often it rests in shade during the heat of the day with the crest raised, mouth open, eyes half shut, and wings drooped to aid in cooling.

Medium-sized shorebird with bright yellow legs. Plumage is essentially identical to Greater Yellowlegs: gray upperparts with white speckling, streaky neck, and white belly. Proportions are most important for identification. Lesser is smaller overall with shorter, narrower, straighter bill, shorter neck, more rounded head, and smaller chest. Forages actively on mudflats and in shallow pools and marshes, often in loose mixed flocks with Greater Yellowlegs. Somewhat more likely to be found in smaller, marshier habitats than Greater, but much overlap. Listen for soft, whistled “tew” calls, typically only one or two notes, unlike the stronger series of notes from Greater.

Very small woodcreeper of evergreen forest in humid tropical lowlands and foothills. Creeps up trunks, often in spirals, picking at the bark for food, then flies low to another tree before hitching upwards again. Forages on fairly large trunks as well as slender trees. Often travels with mixed-species feeding flocks. Note the short, wedge-shaped bill and pale buffy breast spotting.
