Southern Marquesan Reed Warbler

Small, glittering hummingbird found in cloud forest along the east slope of the Andes. It is shining green with white leg puffs and has an irregular white patch on the underparts that is variable in size. Underparts may shine iridescent blue at certain angles in good light. Sexes similar. Uncommon inside humid forest at middle elevations, occasionally coming into clearings where there are abundant flowers or feeders.

Poorly known thistletail found only in a small area of the high Andes east of the city of Ayacucho in southern Peru. It is brown above, gray below, with a long wispy tail and a reddish-orange chin patch. It has a darker chin patch than Vilcabamba Thistletail and Puna Thistletail, and is not known to overlap with either species. It inhabits scrub and stunted forest near treeline. Song is a rapid, high-pitched trill.

Small flycatcher with gray cap, black ear patch, and buffy wingbars. Head pattern looks messy. Olive back and pale yellow belly. Most similar to Sepia-capped Flycatcher, but that species has a brown cap (not gray). Also very similar to bristle-tyrants of South America but note buffy wingbars and voice—a commonly heard, explosive “pseek!” sometimes with a sputtering trill at the end. Look for singles or pairs in forests and edges, usually not too high in the trees. Often follows mixed-species flocks.
