Two-banded Warbler
Myiothlypis bivittata
Small, yellowish bird with a fine black bill and distinctive black stripes on head. Mostly green above and yellow below; has rufous or orange crown bordered by black, but crown color can be difficult to ascertain. Note olive eyebrow becoming yellow in front of eye, and bright pinkish-yellow legs. Inhabits dense understory of foothill forests along the eastern slope of the southern Andes and in the tepui region. Usually occurs in pairs or small family groups that forage actively for insects, often joining mixed-species flocks. Song in tepuis is a series of chips followed by a high-pitched, screeching note. In southern part of range, song is very different: a rich rollicking series of notes that may vaguely recall House Wren and is often given by pairs as a duet. In southern Andes, most similar to Golden-bellied Warbler but has olive (not entirely yellow) eyebrow; also similar to Golden-crowned Warbler but typically occurs at higher elevations and has olive (not whitish) eyebrow.

Mangrove Pitta
Pitta megarhyncha
The huge crab-smashing bill of this mangrove specialist sets it apart from all other pittas. Brightly colored with a black mask, green-and-black wings, and a yellow belly. Similar in color to Blue-winged Pitta, but note Mangrove’s larger-headed appearance and habitat. Like other pittas, shy and difficult to see; listen for its throaty and fluid two-parted whistles.
Cozumel Emerald
Cynanthus forficatus
Only on Cozumel Island, Mexico, where it is usually the most frequently encountered hummingbird. Feeds low to high on a variety of flowers, preferring forest edge, gardens, and other semi-open habitats. Male is stunning, emerald-green with a long, deeply forked tail. Female has distinctive broad dark facemask, rather long forked tail. No similar species on the island (Canivet’s Emerald occurs on the Yucatan mainland).
Common Miner
Geositta cunicularia
Widespread but often local in open areas typically with sandy soil from Patagonian steppe to coastal dunes to bogs in the high Andes; often less common than other miners in the same areas. Often seen in pairs, walking with a waddling gait and pumping its tail like most miners. Best identified by distinct breast streaking, relatively long and very slightly decurved bill, and (in flight) bright rusty wing patches. Northern populations also have contrasting creamy white rump. Song varies geographically.
