Puna Pipit

Brilliant sky-blue warbler of the high canopy. Prefers mature deciduous forest, either in riparian areas or dry mountain ridge-tops. Tends to stay high in the canopy; thus, can be difficult to see blue color. From below, look for white throat and belly, thin necklace, and dark streaks on sides. Female is a unique muted turquoise with pale eyebrow and blurry streaks on sides. Immature birds show yellow wash on underparts. All plumages have bold white wingbars. Easiest to detect in spring and summer by its loud buzzy song, similar to Black-throated Blue but usually richer and more distinctly three-parted; much lower-pitched than Blackburnian Warbler. Winters primarily on the east slope of the Andes from Venezuela to Bolivia.

Medium-sized, fairly long-tailed antshrike of lowland rainforest. Perches upright in the under and midstory of mature rainforest, bamboo, and occasionally forest edges. The male is slaty gray overall while the more distinctive female has a red-orange belly. Often joins mixed-species flocks, where it typically forages slightly higher in vegetation than the similar Dusky-throated Antshrike. Males are best separated from other plain gray antshrikes by more upright posture, slightly longer tail, cleaner gray throat, and voice. Listen for a short series of rising whistles that accelerate into a trill.

An East Asian teal-like duck. Males are distinctive, with an iridescent head that flashes green and copper, a silvery body with distinct scalloping, extremely long curved tertials, long pale scapulars, and a triangular white throat patch outlined in dark green. Brownish females resemble female Gadwall but have a dark bill. Breeds in northern interior marshes and winters on rivers, lakes, and coastal wetlands, often in flocks with other ducks.
