分类信息
Some authors have suggested that the Venezuelan wood quail and gorgeted wood quail (Odontophorus strophium), Tacarcuna wood quail (O. dialeucos), black-fronted wood quail (O. atrifons), and black-breasted wood quail (O. lecuolaemus) are actually a single species, but this treatment has not been accepted by the major avian taxonomic systems. The species is monotypic.

Shelley's Eagle-Owl
Ketupa shelleyi
Very large, dark rainforest owl. Note the dark brown upperparts, heavily barred underparts, and dark eyes. Rare and local in lowland rainforest, including forest edge. The call is a single long, descending whistle: “hrroooooouw,” repeated after long pauses. Shelley’s Eagle-Owl is much larger than other rainforest eagle-owls. Overall coloration most similar to Akun Eagle-Owl, but Shelley’s has dark rather than yellow eyes. Similar in size to Verreaux’s Eagle-Owl, but darker and heavily barred below.
Rose-faced Parrot
Pyrilia pulchra
Beautiful parrot found in Andean cloud forest in western Ecuador and western Colombia. Green with golden breast and neck, and a red face bordered with black. Nothing similar occurs in range. Most often encountered flying rapidly overhead in small flocks that give piercing shrieks. Feeds on fruiting trees, usually high in the canopy, but sometimes descends lower where there is abundant food.
Whistling Heron
Syrigma sibilatrix
Multicolored heron, with a dark cap, pale neck and a pinkish bill with a black tip that contrasts with its blue eyerings. Often found in drier areas than other herons such as natural grasslands and agriculture areas, but also sometimes found in marshes. Unlike other herons, it is rather vocal; often uttering a distinctive metallic whistle.
