Schlegel's Asity

Males are bright yellow overall save for the black wings and inner tail feathers. Note the yellow patch on the wings, the yellow outer tail feathers, the black stripe through the eye that gives it a masked appearance, and the fleshy pink bill. The female is dull greenish-yellow overall with dirty brown/green wings and a completely yellowish tail. Both males and females have red iris. Most often found feeding in tree canopies either singly or in pairs. They generally give a harsh “krrrrrrrrrrrr” call while feeding. In flight, note its characteristic dipping flight style.

Small, retiring quail of forest understory. Rarely seen, but can be located by listening for noisy rustling in the leaf litter as birds scratch like chickens. Prefers to run away rather than flush. Loud song often reveals its presence, given mainly early and late in the day: first few notes similar to Little Tinamou song, but then breaks into rollicking choruses that can be almost deafening if close by. Male has rusty face and gray body, female colors reversed, with gray face and rusty body.

Small warbler with sharply pointed bill. Look for gray head, white eyering, yellow underparts (including throat), and olive upperparts. Sometimes pumps tail. Two disjunct breeding populations are very similar in appearance. Breeds in coniferous or mixed forests, often near clearings, second-growth, or bogs. In migration and winter, tends to be found in patchy woodland or brushy areas, including field edges and thickets. Winters primarily in Mexico. Listen for its loud chipping song, broken into two parts. Compare dull immature Nashville with Virginia’s Warbler; Nashvilles always have greenish wings. Also sometimes mistaken for larger gray-headed warblers like Mourning or Connecticut, but Nashville is much smaller, shorter-tailed, and sharper-billed.
