Jerdon's Bushchat

Marginally larger than Great Spotted Woodpecker, but appears distinctly longer-billed. White back in some subspecies is not always obvious when perched but easy to see in flight. Streaky flanks are distinctive. Also note varying amounts of red on the lower belly and undertail. Gives a somewhat hoarse “kik”, sometimes in rattled series. Drum is fast and fades towards the end. Found in mature undisturbed deciduous and mixed forest with lots of dead trees; sometimes near water, as well as in recently burned areas. Threatened by habitat loss in much of its range.

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.

Medium-sized blackbird found locally in habitats with wet grass. Shiny black, with a white or light yellow eye and sharply pointed black bill. Giant Cowbird occasionally has a pale eye and may appear similar, but is much larger than Pale-eyed Blackbird; told apart from the similar Velvet-fronted Grackle by its pale eyes, longer, more pointed bill, and shorter tail. Found in wet grasslands and grassy margins of oxbow lakes, where it forages singly, in pairs, or in small groups.
