White-bellied Bustard

While the male does have a pale crown, his broad, round-edged black mask is far more noticeable. Female is plainer, with a brown crown and a small pale mask; the similar European and Chinese Penduline-Tit females have darker, more prominent masks. Breeds in shrubs and low trees in wet areas and winters in reedbeds, forests, and scrubby areas. Call is a drawn-out plaintive whistle, and song is short, ending on a decisive “chip” note.

The most widespread rosy-finch. Body is the color of milk chocolate. Look for pink highlights in the wings, tail and belly. Several different populations; some have gray wrapping around the back of the head only above the eye, others have entirely gray cheek. Breeds at the highest elevations; descends to lower elevations in winter. Often in mixed flocks in winter with other rosy-finches. Feeds on seeds and insects. Look for them foraging on alpine snowfields. Visits feeders, primarily in winter.

Rather long-tailed antbird of humid forest understory in lowlands and mountains from Colombia to Bolivia. Usually stays hidden in dense vegetation and thickets, sometimes attending army antswarms. Male is black; female is extremely variable throughout range. On the west slope of the Andes in Ecuador and extreme northwestern Peru, female is plain brownish with no distinctive features. On the east slope of the Andes from Colombia to northern Peru, female has black body and rufous-brown upperparts. In central Peru, female is entirely rufous-brown with a black head. From southeast Peru to Bolivia, female is rufous-brown overall with a tawny chest and a distinctive pale eyebrow. Both sexes have ruby-red eyes and a white patch on the back that is usually hidden; it is exposed when the bird is excited such as when defending its territory. Song is a very fast series of short whistles.
