Large-tailed Dove
Leptotila megalura
A medium sized, chunky dove of the interandean dry valleys, yungas, and Tucumán forest with mixed Podocarpus and alders. Often alone or in pairs. Orbital ring varies from blue-purple north of the bend in the Andes to red south of this bend. Range overlaps with the very similar White-tipped Dove, and is best separated by voice, and, in some populations, orbital skin color (blue in White-tipped Dove). Iris also generally darker than White-tipped Dove. Most often found and easily identified by its low-pitched, stuttering song.

Its upperparts and tail are a dark ruddy brown with a purple gloss on the hindneck and upper mantle. Its breast and the sides of the neck are grayish pink lightening to white on the belly.

Guianan Tyrannulet
Zimmerius acer
Tiny, inconspicuous flycatcher; in addition to small size, note stubby bill, wing bars, and longish tail. Found in a variety of forest habitats including primary and secondary rainforest, low-stature forests with sandy soils, and along river edges. Often sits on leaf clusters at the ends of branches, sallying for insects; also feeds on fruit. Heard far more than seen. Most common call is a dry, two-noted hiccup that is easily overlooked; dawn song is a repeated, rising twitter.

Xenoperdix udzungwensis
An unusual forest-dwelling partridge with a tiny range in the mountains of central Tanzania. The back is brown and barred, the underparts are gray with black scallops, and the bill is red. Found very locally in montane forest, especially in steep areas with bamboo. Somewhat similar to Scaly Francolin, but separated by smaller size and far more colorful markings. Most often detected by call: a repeated “kur-kur-kree” chant.
