Blackthroat

Rotund, brown bird with long legs and a short tail restricted to the Bolivian Andes. Looks rather plain in the field, though may show a buffy tinge to the underparts. Similar to Leymebamba Antpitta, but larger, longer legged, and lacks gray in the plumage. Vocalizations include a whistled “wit-do” and a trill that drops slightly in pitch and then rises. It was formerly considered a subspecies of what used to be called Rufous Antpitta.

A relatively small diving duck with a tall peaked crown. Males are handsome with glossy black head and back, clean gray sides, and a brighter white spur on the side. Females are grayish-brown, often with a paler patch at the base of the bill and a white eyering. Both sexes have a white band near the tip of gray bill. Also note gray, not white, wingstripe in flight. Usually favors small bodies of water, such as beaver ponds and cattail marshes, but also occurs on larger lakes, rivers, and bays. Can be found in mixed flocks with other diving ducks, although usually in smaller numbers than scaup. Compare with both species of scaup and Redhead (especially females).

Dark and mostly drab sunbirdlike inhabitant of tropical forests, plantations, and gardens. Iridescent purple nape and rump are diagnostic, but can easily be missed in the gloom of dense forest. Olive-green upperparts and streaked belly, along with a dark, slightly curved bill, are sufficient to distinguish this species from other spiderhunters and sunbirds in its range. Like many other spiderhunters, calls loudly, harshly, and persistently as it forages.
