Birds

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.

This batara has a strong hooked beak with which it catches various insects and spiders. It is generally seen in pairs following mixed flocks. Thamnophilus derives from the Greek thamnos = bush and philos = lover of, referring to their habit of moving at low heights among the bushes. Its epithet nigrocinereus refers to its coloration and derives from the Latin niger = black and cinereus = ash color.

This species is endemic to the Sierra Nevada de Santa Marta in Colombia and is probably closely related to G. kaestneri. Its name Grallaria derives from the modern Latin grallarius = stiltwalker and its epithet Bangsi was established in honor of the American zoologist and collector Outram Bangs.

The gray kingbird or grey kingbird, also known as pitirre, petchary, or white-breasted kingbird (Tyrannus dominicensis) is a passerine bird. It breeds from the extreme southeast of the United States, mainly in Florida, through Central America, from Cuba to Puerto Rico as well as eastward towards all across the Lesser West Indies, south to Venezuela, Trinidad, Tobago, the Guiana, and Colombia. Northern populations are migratory, wintering on the Caribbean coast of Central America and northern South America. Several vagrant populations are known to exist in the American Northeast.

The Batara Unicolor is found in humid and very humid jungles of the three mountain ranges of Colombia. It deliberately moves in pairs from undergrowth to sub-canopy and climbs vines like other Batara. Thamnophilus derives from the Greek thamnos = bush and philos = lover of, referring to their habit of moving at low heights among the bushes. Its unicolor epithet derives from Latin and means one color.

The Yellow-throated Vireo is a rare migratory species found in Colombia from the beginning of December to the end of March. Within the family vireonidae it is one of the species with the brightest colors. Its name Vireo derives from Latin which means small green migratory bird. Its epithet flavifrons derives from the Latin flavus which means yellow and frons in front, referring to its appearance.
