Puerto Rican Amazon

Large, short-tailed antbird of floodplain forest understory. Both sexes largely gray with a bare blue skin patch around the eye and a prominent white spots on the shoulder. Females are particularly distinctive with extensive orange underparts. Forages singly or in pairs in dense undergrowth, like heliconias and streamside vegetation. Song is a chortling accelerating trill.

Attractive sparrow found along the western edge of the Andes in northwestern Argentina, barely reaching over the border into Bolivia. Note the chestnut head stripes, dark smudge between eye and bill, and black and white mustache. Similar to Chaco Sparrow, with which it was formerly lumped as Stripe-capped Sparrow, but is larger with more extensive black on the face, rustier wings, and a different voice. Inhabits open, grassy habitats with scattered trees and low scrub. Song is a slow series of wheezy chirps.

Drab, undistinguished-looking bulbul. Predominantly gray-brown with a white throat and slight rufous tones on the wings and tail. Pale eye and unmarked head distinguish it from other plain brownish bulbuls within its range. Tends to be seen solitarily or in pairs but will occasionally join mixed flocks or forage in larger groups at fruiting trees. Unmusical; gives a loud, ringing nasal note, often repetitively.
