分类信息
The white-headed munia was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Loxia maja. Linnaeus cited George Edwards's "The Malacca Gros-beak" and Mathurin Jacques Brisson's "Le Maia de la Chine". The English naturalist John Ray used the word "Maia" for a Cuban bird in 1768. Linnaeus specified the locality as East India. This was amended to Malacca in 1924. The white-headed munia is now placed in the genus Lonchura that was introduced by the English naturalist William Henry Sykes in 1832. It is treated as monotypic: no subspecies are recognised.

Napo Sabrewing
Campylopterus villaviscensio
Large, dark hummingbird found in cloud forest along the east slope of the Andes. Ranges from far southern Colombia south to northern Peru. Male has large blue patch on throat and breast, and a glittering green crown. Female has gray underparts; she is similar to Gray-breasted Sabrewing but has narrower white tail tips. Also note white spot behind eye. Infrequently encountered, though does visit feeders in some areas.
Lesser Hornero
Furnarius minor
The smallest hornero. Plumage rusty overall with a white eyebrow, a gray crown, and a white throat. Note the gray legs. Found in scrub on river islands and occasionally in human-modified habitats near major rivers. Forages walking on the ground, especially at the water’s edge. The song is a series of fast staccato “kee” notes, usually given in duet. Other horneros with overlapping distributions have longer and louder songs.
Pavonine Quetzal
Pharomachrus pavoninus
Stocky green-and-red quetzal of lowland rainforest. Perches in the mid story of mature rainforest, where most common in upland (terra firme) areas and areas around water. Compared to trogons, is larger and chunkier, with a red bill and without a prominent eye ring. The green uppertail coverts are long, extending down the back side of the tail to just past the tail tip. Listen for its song, a repeated two note series of a breathy whistle followed by a soft note, “wheeew … tuck … wheeew … tuck …”.
