About Tangara schrankii (Spix, 1825)
The green-and-gold tanager, with the scientific name Tangara schrankii, is a species of bird in the tanager family Thraupidae. It is one of 27 species that belong to the genus Tangara. This bird is found in the western and central Amazon Basin, within the territories of eastern Venezuela, Colombia, Ecuador, Peru, central Bolivia, and northwestern Brazil. Its natural habitats are subtropical or tropical moist lowland forests, and subtropical or tropical swamps. The full range of the green-and-gold tanager covers nearly all of the western Amazon basin, extending up to the higher elevation mountain foothills of the eastern Andes. Its continuous range includes three separate extended sections. A southern extension stretches approximately 2000 km long and 400 km wide from southern Peru into central Bolivia, covering the upper reaches of tributary rivers that feed the northeast-flowing Madeira River in Bolivia. A 1300 km northern extension reaches the higher elevation border region of southeastern Venezuela, running from the Amazon's Rio Negro beyond the upper reaches of Venezuela's Orinoco River, which flows northward to the Caribbean. The third extension extends eastward into the central Amazon basin, and stops only at the middle reaches of the north-flowing Tapajós River, covering an 800 km stretch of this 3000 km long river.
