The bay-headed tanager (Tangara gyrola) is a medium-sized passerine bird. This tanager is a resident breeder in Costa Rica, Panama, South America south to Ecuador, Bolivia and north-western Brazil, and on Trinidad.
The bay-headed tanager was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Fringilla gyrola. [2] The specific epithet is a diminutive of the Latin gyrus meaning "ring". [3] Linnaeus based his own description on the "red-headed green-finch" that had been described and illustrated by the English naturalist George Edwards in 1743 in his A Natural History of Uncommon Birds. [4] The type locality is Suriname. [5] The bay-headed tanager is now placed in the genus Tangara that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. [6] [7]
Nine subspecies are recognised: [7]
Adult bay-headed tanagers are 14 cm long and weigh 19.5 g. The nominate race T. g. gyrola is mainly green apart from a chestnut head, a blue or green belly, and a thin gold collar on the hind neck. Sexes are similar, but immatures are duller with chestnut-flecked green heads. There is considerable plumage variation between the various subspecies, and T. g.viridissima of northeast Venezuela and Trinidad has green underparts concolorous with the rest of the body plumage.
The bay-headed tanager's song is a slow seee, seee, seee, tsou, tsooy.
It occurs in forests, particularly in wetter areas. The bulky cup nest is built in a tree and the normal clutch is two brown-blotched white eggs. The female incubates the eggs for 13–14 days to hatching, with another 15–16 days before the chicks fledge.
These are social birds which eat mainly fruit, usually swallowed whole. Insects are also taken, mainly from the underside of branches.
The blue-gray tanager is a medium-sized South American songbird of the tanager family, Thraupidae. Its range is from Mexico south to northeast Bolivia and northern Brazil, all of the Amazon Basin, except the very south. It has been introduced to Lima (Peru). On Trinidad and Tobago, this bird is called blue jean.
The turquoise tanager is a medium-sized passerine bird in the tanager family Thraupidae. It is a resident bird from Trinidad, much of Brazil, Colombia and Venezuela south to Bolivia. It is restricted to areas with humid forest, with its primary distribution being the Amazon. It was formerly treated as being conspecific with the white-bellied tanager which is found in the Atlantic Forest of eastern Brazil.
The green honeycreeper is a small bird in the tanager family. It is found in the tropical New World from southern Mexico south to Brazil, and on Trinidad. It is the only member of the genus Chlorophanes.
The purple honeycreeper is a small Neotropical bird in the tanager family Thraupidae. 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 red-legged honeycreeper is a small songbird species in the tanager family (Thraupidae). It is found in the tropical New World from southern Mexico south to Peru, Bolivia and central Brazil, Trinidad and Tobago, and on Cuba, where possibly introduced. It is also rarely found in southern Texas.
The blue dacnis or turquoise honeycreeper is a small passerine bird. This member of the tanager family is found from Nicaragua to Panama, on Trinidad, and in South America south to Bolivia and northern Argentina. It is widespread and often common, especially in parts of its South American range.
The red-capped cardinal is a small species of bird in the tanager family Thraupidae. It is found in South America.
The saffron finch is a tanager from South America that is common in open and semi-open areas in lowlands outside the Amazon Basin. They have a wide distribution in Colombia, northern Venezuela, western Ecuador, western Peru, eastern and southern Brazil, Bolivia, Paraguay, Uruguay, northern Argentina, and Trinidad and Tobago. It has also been introduced to Hawaii, Panama, Puerto Rico and elsewhere. Although commonly regarded as a canary, it is not related to the Atlantic canary. Formerly, it was placed in the Emberizidae but it is close to the seedeaters.
The yellow-green grosbeak is a species of grosbeak in the family Cardinalidae.
The purple-throated euphonia is a songbird species in the family Fringillidae. It was formerly placed in the Thraupidae.
The fulvous shrike-tanager is a South American bird in the tanager family Thraupidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitat is subtropical or tropical moist lowland forests.
The short-crested flycatcher is a species of bird in the tyrant flycatcher family Tyrannidae.
The ruddy-breasted seedeater is a species of bird in the tanager family Thraupidae. It is found in Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Suriname, Trinidad and Tobago, and Venezuela. Its natural habitats are dry savanna, subtropical or tropical seasonally wet or flooded lowland grassland, and heavily degraded former forest.
The flame-crested tanager is a species of bird in the family Thraupidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical dry shrubland. Ten subspecies are currently recognized.
The fulvous-crested tanager is a species of bird in the family Thraupidae, the tanagers.
The burnished-buff tanager, also known as the rufous-crowned tanager, is a common South American species of bird in the family Thraupidae.
The rufous-winged tanager is a species of bird in the family Thraupidae. It is found in Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, and Panama. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest.
The spotted tanager is a species of bird in the tanager family Thraupidae. It is found in Bolivia, Brazil, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The opal-rumped tanager is a species of bird in the family Thraupidae. It is found in the Amazon and Atlantic Forest of South America. The population of the Atlantic Forest has a far paler chest than the other populations, and has often been considered a separate species as the silvery-breasted tanager. Today most authorities treat it as a subspecies of the opal-rumped tanager.
The white-bellied tanager is a medium-sized passerine bird in the tanager family Thraupidae. It is a resident bird of the Atlantic Forest of eastern Brazil. It is restricted to areas with humid forest. It was formerly considered as a subspecies of the turquoise tanager.
