The slaty-breasted wood rail appears to be a year-round resident throughout its range.<p>Usually feeds earthworms, beetle larvae and other small insects.<p>The slaty-breasted wood rail's breeding season has not been fully defined but appears to include at least November to February. One nest is known; it was in a thick bush and held four or five eggs. Nothing else is known about the species' breeding biology.<p>The slaty-breasted rail mostly calls during the day. It makes a "[v]ariety of loud, resounding, noisy cries, including 'po-quit kwaa kwaa kwaa', 'po-peek' and 'po-pereek'", often for many minutes and usually in a duet. Another vocalization is "an irritated, rapidly repeated series of 'quir' notes".

Bendire's Thrasher
Toxostoma bendirei
Dusty-brown bird with long tail, found in shrubby deserts and grasslands. Tail dark with small white corners; undertail coverts warmer orangey. Eye yellow. Very similar to Curve-billed Thrasher. Subtle differences include smaller, more triangular-shaped markings on breast, and shorter, straighter bill. Shy; often hard to spot on the ground but sometimes perches conspicuously when singing. Ages and sexes similar; juveniles show faint buffy wingbars. Listen for jumbled, rambling song.
Brown Falcon
Falco berigora
Large-headed falcon with variable brownish plumage ranging from dark chocolate brown, to reddish, to tan. All have a dark moustache mark, long unfeathered lower legs, and a finely barred tail. Take care to identify dark birds from Black Falcon, which has feathered legs, and a more angular heavy-shouldered appearance. When gliding holds its wingtips up. Common resident in rural areas, often perches on power lines, fence posts. Populations tend to move when food and water is scarce.
Guianan Streaked-Antwren
Myrmotherula surinamensis
Tiny bird of riverside vine tangles and seasonally flooded forest. Distinctive male is black-and-white while female has burnt orange head and breast; both easily recognized in riverside habitat. Usually found in pairs away from mixed-species flocks. Forages actively, climbing through vines and gleaning insects from leaves. Frequently detected by contact call: a nasal doubled note. The more complex song is heard less often.
