Scarlet-rumped Trogon

A medium-sized typical nightjar with a golden-buff collar. Both sexes have small pale marks in the outer wings and at the corners of the tail. These are larger and whiter on males, and smaller and more buffy in females. Generally local and uncommon in savanna and grassland habitats, often in rocky areas. Similar to Nubian Nightjar, but darker overall, with less rufous in the wings. Also similar to many other nightjars, and best identified by voice. Call is a high-pitched, mechanical trill, similar to that of Plain Nightjar, but slightly lower-pitched.

Bold patterned gnatcatcher usually found in the canopy of savanna, open woodlands, and forest edges where it may join mixed-species flocks. Largely grayish overall with a white-edged black tail. Males have a black mask while females have a small black ear patch on a generally pale face. Males of the subspecies from Northwest Brazil are whiter below and grayish in other populations.

Relatively small antbird with heavily streaked upperparts, spotted chest, and rusty lower back and belly. Inhabits the understory of humid forest, seasonally flooded forest, and tall second growth. Forages in dense vine tangles, and sometimes accompanies mixed-species flocks or attends army-ant swarms. The song is a descending series of 9-10 clear notes ending abruptly. Similar to Rondonia Warbling-Antbird, but Spix's Warbling-Antbird has a black (not gray) mantle and a more heavily streaked breast, while the back of females is less streaked and duller brown.
