Hudson's Black-Tyrant
Knipolegus hudsoni
Highly migratory flycatcher that breeds in central Argentina from around September through March, then disperses north to Bolivia and Paraguay, and occasionally wanders even farther. Male is glossy black with a silvery, black-tipped bill. He has a white on the underside of the wing that is usually hidden while perched. Female is brown and buff with white wingbars, cinnamon rump and tail base, and faint mottling on the breast. Very similar to White-winged Black-Tyrant; female is paler on the breast and belly, but males are virtually indistinguishable in the field. Inhabits stunted forest, scrub, and overgrown clearings.

Ryukyu Scops-Owl
Otus elegans
Diminutive brownish owl with short ear tufts and pale face narrowly bordered in black. Combination of overall brown coloration, yellow eyes, and small size distinguishes it from the larger Oriental and Japanese Scops-Owls. Like other scops-owls, often difficult to see; listen for its hiccuping hoots, given in a long series. Inhabits forests and adjacent edges throughout its range.
Crimson-collared Grosbeak
Periporphyrus celaeno
Stocky and often rather sluggish bird of tropical forest and edge in lowlands and foothills of northeast Mexico. Usually found as singles or pairs, feeding quietly at all levels in fruiting trees or bushes. Note the thick stubby bill and rather long tail. Adult male is striking: dark overall with a black hood and broad pinkish-red collar. Female is drab greenish overall with black hood similar to male. Immature is like female but with less extensive black hood.
Planalto Hermit
Phaethornis pretrei
Large hummingbird with an olive-green back contrasting with its cinnamon rump and belly. Note slightly curved bill with a red lower mandible and prominent dark mask. The tail is long with eye-catching white tips. Avoids forests; found in grasslands, shrubby areas, wooded savannas, and at forest edges.
