Little Green-Pigeon
Treron olax
This aptly-named forest species is the smallest of the green-pigeons. Males are highly distinctive, with a blue-gray head and neck, orange chest, pinkish-maroon back, and green belly. Females are duller, but their combination of size, gray crown, and contrasting yellow-green chest serves to tell them apart from other green-pigeons. Pairs often forage and perch together, often on exposed bare branches. Like other pigeons, frequently gathers at fruiting trees. Song is a series of strangely buzzy rising whistles.

Other Birds
Yellow-browed Antbird
Hypocnemis hypoxantha
Rather small antbird with a disjunct distribution. Males have a yellow face and underparts with a black crown, eye-line, and streaks on the breast. Females have a yellow streaked crown. Southeastern subspecies has ochraceous lower underparts. Song is a descending and decelerating series of fluted notes becoming harsher at the end. Found in the understory of humid forests, often in areas of transitional forest or poor soils. Rarely accompanies mixed-species flocks. The similar Spix's and Peruvian Warbling-Antbirds have white breasts, and the song of Peruvian is somewhat slower-paced.
Southern Pochard
Netta erythrophthalma
Very dark-looking duck with a broad white wing band that is visible in flight. Males are mostly glossy black with chestnut wings and a pale gray bill. Females have a different head pattern with white at the bill base and a crescent behind the eye. Inhabits lakes and pools with abundant vegetation.
Rufous Fieldwren
Calamanthus campestris
Small bird of open arid shrubland and grasslands. Pale brown above, whitish below, with distinct pale supercilium, faint chest streaking, and long, cocked tail. Forages quietly on the ground or in thick vegetation, where difficult to see. Most easily observed when males sing in spring, as they perch up in the vegetation. Similar to Western Fieldwren but no range overlap. Compare Shy Heathwren, which has a white wing spot and darker legs.
