Chocolate-vented Tyrant
Neoxolmis rufiventris
Wonderfully (if poorly) named large terrestrial flycatcher of open windswept habitats in Patagonia, especially bunch grass and open shrub-steppe with grassy patches; migrates north in winter. Usually seen as singles or pairs, perched on roadside fences or flying low over the ground, when flashy and distinctive wing pattern is striking: broad white trailing edge contrasts with bright rusty panel in center of wing. Runs well on the ground, when it may suggest a thrush. Note dark face, frosty pale wing panel, and pale rusty belly.

Plain-winged Antwren
Myrmotherula behni
Small, rare antbird found in lush cloud forest along the east slope of the Andes and in the tepui region of Venezuela, Guyana, and extreme northern Brazil. Male is dark gray with black throat and breast; extent of black is geographically variable. Female is brown with a pale throat. Similar to Slaty Antwren but lacks wing markings. Inhabits forest understory, where often encountered with mixed-species flocks. Song is a series of four to ten soft whistles.

Madagascar Forest Rail
Mentocrex kioloides
Chunky rail with rich rufous coloration and a gray patch on the face. Found on the floor of eastern and northern rainforest, though it nests in trees. Usually in pairs or small groups. Very shy, and looks almost like a mammal when scurrying away from disturbance. Most common call is a long, ringing series of “kheow” notes. Also gives deep grunts and an explosive “tshak” call. Similar to Brown Mesite, but chunkier and shorter-tailed, with darker underparts. Told from Tsingy Wood-Rail by range. Smaller than White-throated Rail, with a shorter bill and a much smaller white throat patch.

Black-headed Gonolek
Laniarius erythrogaster
Boldly patterned black-and-red bushshrike with pale eyes. The immature has pale underparts with fine dark bars. Found in thick woodland, lush scrub, and overgrown cultivation, where it usually skulks in the undergrowth. The male gives a rising, whistled “wheeo-eo,” and the female a low ratcheting call. These two are often given in a perfectly synchronized duet. Similar to Papyrus and Yellow-crowned Gonoleks, but has an all-black rather than yellow crown.
