Black-and-chestnut Warbling Finch

Large striking flycatcher of tropical and subtropical forest and woodland; also in semi-open areas with taller trees. Perches mainly at mid-upper levels, often in the canopy. Fairly common in most areas, but uncommon and local in West Mexico. Told from widespread Great Kiskadee, which prefers more open and less wooded habitats, by dull olive upperparts (lacking the bright rusty wings and tail of kiskadee) and stouter bill, with a more strongly arched ridge along the top. The two species sound quite different.

Small and distinctive warbler-like bird, often difficult to see well. The male has a black head with contrasting white eyebrows and throat, gray upperparts, and striking pinkish-red underparts. The female has a buffy face, chest, and undertail coverts, whitish belly, and gray upperparts. Prefers canopy vine tangles and river edges, where it may occur lower; creeps through vegetation, alone or with mixed-species flocks, feeding on insects. Generally uncommon and inconspicuous. Plumage is unlike any other species in range. Song is a series of soft, rising whistles.

Small finchlike bird, compact and short-tailed. Generally yellow below and dark blue-black above with stout bill. To identify male euphonias, focus on crown and throat: on Thick-billed, crown is entirely yellow and throat is yellow. Females are extremely difficult to separate from other euphonias, especially Yellow-crowned, but often seen in pairs or small groups with more distinctive males. Frequents open forested habitats, edges, and gardens. Can form mixed feeding flocks with other species such as warblers and tanagers.
