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.

行为

Brown falcons and other Australian firehawks have been said to pick up sticks with flames and dropping them to spread fires and prey on escaping animals. According to Audubon, "That anecdotal evidence is sourced from personal testimonies by Australian firefighters and aboriginal people, as well as historical literature, and amounts to 14 firsthand narratives of this specific occurrence."

Malagasy Harrier

Malagasy Harrier

Circus macrosceles

A typical harrier, with long slender wings and tail and graceful swooping flight. Male has pale gray panels in the wings, while female is browner and more uniform. Found mainly in open habitats, including marsh and montane grassland. Occasionally seen flying over forest. Spends long periods on the wing and is rarely seen perched. Most often confused with Black Kite, but has longer wings, a longer, narrower, and un-forked tail, a white rump, and pale underparts. Coloration overall similar to other raptors like Madagascar Buzzard, but lanky harrier shape is distinctive.

Noble Snipe

Noble Snipe

Gallinago nobilis

A typical-looking snipe found at high elevations in the Andes from extreme western Venezuela to northern Peru. Intricately patterned with brown, black, and white. Compare with Andean Snipe; Noble is paler overall with an unmarked white belly, more obvious white stripes on the upperparts, and a longer bill. Scarce; usually seen singly in marshes or bogs in páramo, often only when flushed.

Rufous-headed Chachalaca

Rufous-headed Chachalaca

Ortalis erythroptera

Large chickenlike bird with a long tail. No similar species in limited range; much smaller than Crested Guan and warmer brown than Sickle-winged Guan. Note contrasting reddish-brown head; wings and tail also rufous but more easily visible in flight. Nearly endemic to Ecuador, but occurs in extreme southwestern Colombia and northwestern Peru. Look for pairs or small groups in the mid-levels of forest and edge, up to around 1,800 m. Like other chachalacas, has a very raucous and exceptionally annoying voice.
