The yellow-crowned amazon or yellow-crowned parrot (Amazona ochrocephala) is a species of parrot native to tropical South America and Panama. The taxonomy is highly complex and the yellow-headed (A. oratrix) and yellow-naped amazon (A. auropalliata) are sometimes considered subspecies of the yellow-crowned amazon. Except in the taxonomic section, the following deals only with the nominategroup (including subspecies xantholaema, nattereri and panamensis).They are found in the Amazon basin.

The common sparrow (Passer domesticus), also called pardal [2] or chilero, is a species of passerine bird of the Passeridae family. It is adapted to the urban habitat to the point of being the most frequent and well-known bird in those areas, although in absolute terms the finch is more abundant. Live as a commensal of the human being. It is native to Eurasia and North Africa, but is currently distributed in urban areas in temperate zones of almost the entire world, as it has been introduced by humans in the rest of the continents, with the exception of Antarctica.

Bird of activity mainly twilight and nocturnal. It lives in dry areas in the north of the country and east of the Andes. Its name Burhinus means ox beak and derives from the Greek roots bous = ox and rhinos = beak.

The purple honeycreeper (Cyanerpes caeruleus) is a small bird in the tanager family. It is found in the tropical New World from Colombia and Venezuela south to Brazil, and on Trinidad. A few, possibly introduced birds have been recorded on Tobago. The species is a bird of northern South America, and besides the Amazon Basin and the Guianas, a coastal range occurs west of the Andes, including parts of southern Panama. In the south, its range extends to the extreme western Pantanal. Though it is most frequently seen in the lowlands up to 3,300 ft (1,000 m) ASL or so, it has been encountered as high as 7,500 ft (2,300 m) ASL.
