Whistler's Warbler
Phylloscopus whistleri
One of a confusingly similar complex of species, this medium-sized warbler has a bright yellow eye-ring, a pale and indistinct wingbar, and a grayish crown bordered by two long black stripes. The weakness and greenish cast of the gray crown separates this species from various other “golden-spectacled”-type warblers, such as Gray-crowned. Golden-spectacled Warbler is very similar; in Whistler’s, look out for an unbroken eye-ring, a shorter bill, a longer tail, and slightly duller green upperparts. Whistler’s breeds in high-altitude temperate broadleaf forest from around 2000 meters up to the treeline; averages higher in altitudinal breeding preferences than Golden-spectacled Warbler. Like other “golden-spectacled”-type warblers, Whistler’s typically forages at lower and middle levels of forest, often mixing with other species and making flycatching sallies. Song consists of a 2- or 3-noted whistled phrase repeated 2-3 times without pause, lacking the trills of Golden-spectacled Warbler.

Other Birds
Blyth's Kingfisher
Alcedo hercules
Medium-sized kingfisher of shaded mountain streams in mature hill forest. Like a larger version of Common Kingfisher, but much darker and with no orange behind the ear. Bill is heavy and all-dark; its length and girth give the bird a heavy-headed appearance. Perches low over the water on boulders and low-hanging branches, from which it gives a hoarse, rasping call.
Chilean Woodstar
Eulidia yarrellii
Tiny, highly endangered hummingbird found very locally in the desert of northern Chile. Favors native desert scrub in lowland valleys, but widely eliminated from most areas by intensive agriculture. Male most often detected by insectlike buzz made by wings in flight. Also perches conspicuously atop bushes and on wires; note diagnostic crossed tail feathers. Female similar to Peruvian Sheartail, but has shorter tail with pale rusty bases to outer feathers (hard to see).
Emerald Tanager
Tangara florida
Well-named tanager, mostly emerald-green with trapezoidal black cheek patch, back streaking and wing markings. Small and active, usually found in pairs following mixed feeding flocks in foothill forests and edges. Feeds on fruit. Sexes alike.
