Pied Harrier

Circus melanoleucos

A spectacular harrier patterned in black and silvery white. The male is distinctive with black head, striking yellow cere and eyes, and black shoulders, breast, and wingtips, contrasting with its silvery-white underparts and forewing. The female is gray-and-brown above and lighter below, with a small white rump. Females superficially resemble female Pallid and Montagu’s Harriers, but have a paler underwing with narrow dark barring and sparse streaking on underwing coverts. The species hunts by quartering suitable habitat on buoyant wings. It eats mostly small mammals, amphibians, reptiles, and insects.

Madagascar Forest Rail

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. 

Transvolcanic Jay

Transvolcanic Jay

Aphelocoma ultramarina

Rather large, blue-and-gray jay of highland pine and pine-oak forest endemic to highlands of central Mexico; occurs in transvolcanic belt from Volcánes de Colima in the west to Volcán Orizaba in the east. Typically travels in wide-ranging flocks of 5–25 birds, mainly at middle to upper levels in trees. Appreciably larger and broader-winged than Woodhouse's Scrub-Jays, with plainer plumage (lacks dark mask, whitish eyebrow, and partial dark collar of Woodhouse's Scrub-Jay). Noisy calls carry well.

Golden-fronted Woodpecker

Golden-fronted Woodpecker

Melanerpes aurifrons

Medium-sized woodpecker, plain buffy-brown overall with black-and-white barring on the back. Head pattern varies across range but usually shows some combination of yellow and red. Most males on the Caribbean slope of Mexico and into Central America have a solidly red crown and nape. In flight, look for white rump. Common and conspicuous in open woodlands, deciduous forest, and arid scrub from Texas and Oklahoma south to Nicaragua. Often the default woodpecker close to human settlements. Visits backyards and feeders, especially for oranges and jelly. Hybridizes with Red-bellied Woodpecker at the northern limits of its range and with Hoffmann’s Woodpecker at the southern limits. Also compare with the smaller Yucatan Woodpecker.
