The blue seedeater (Amaurospiza concolor), or Cabanis's seedeater, is a species of bird in the cardinal family Cardinalidae that is found in southern Mexico and Central America. The Ecuadorian seedeater (Amaurospiza aequatorialis) was formerly considered as a subspecies.
The blue seedeater was formally described in 1861 by the German ornithologist Jean Cabanis based on a specimen that had been collected in Costa Rica. Cabanis placed the species in a new genus Amaurospiza and coined the binomial name Amaurospiza concolor. [1] [2] The specific epithet is Latin meaning "uniform", "similar in colour" or "plain". [3]
The blue seedeater was formerly considered to be conspecific with the Ecuadorian seedeater. Most authorities now treat the Ecuadorian seedeateras a separate species. This is based largely on the results of molecular phylogenetic studies that were published in 2014 and 2023. [4] [5] [6] [7] [8] Confusingly, as of January 2024, BirdLife International uses the scientific name A. moesta for blue seedeater. The BirdLife account encompasses what are now the blue, Ecuadorian, and blackish-blue seedeaters. [9]
Two subspecies are recognised: [6]
The blue seedeater is 11.5 to 14 cm (4.5 to 5.5 in) long and weighs 12 to 15 g (0.42 to 0.53 oz). The nominate male is entirely slate blue. The female's upperparts are cinnamon and the underparts tawny. The male A. c. relicta is more slaty (less blue) than the nominate and has black lores; the female is a paler cinnamon. [10]
The songs and calls have been transcribed in several ways. [10] A song from Chiapas, Mexico, is . One from Panama is . A call from Puebla, Mexico, is and one from Panama is .
The nominate blue seedeater is found from Chiapas in southern Mexico through Central America to western and central Panama. A. c. relicta is found in six southwestern Mexico states, Jalisco, Colima, Morelos, Puebla, Guerrero and Oaxaca. The species inhabits openings in and edges of humid montane and secondary forest. It most often is found at sites with bamboo. In northern Central America it ranges in elevation from 600 to 2,500 m (2,000 to 8,200 ft) but in Costa Rica inhabits the narrower range of 1,700 to 2,200 m (5,600 to 7,200 ft). [10]
The blue seedeater's diet includes insects, seeds, and bamboo shoots. [10]
The only known blue seedeater nest was found in Mexico. It was a cup of coarse grass lined with finer grass placed in the fork of a slender branch. It contained two seedeater eggs and one of the brood parasite bronzed cowbird (Molothrus aeneus). [10]
The IUCN has not assessed the blue seedeater.
Cardinalidae is a family of New World-endemic passerine birds that consists of cardinals, grosbeaks, and buntings. It also includes several other genera such as the tanager-like Piranga and the warbler-like Granatellus. Membership of this family is not easily defined by a single or even a set of physical characteristics, but instead by molecular work. Among songbirds, they range from average-sized to relatively large, and have stout features, some species with large, heavy bills.
The tanagers comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds.
The Carrizal seedeater is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is endemic to Venezuela.
The black-faced antthrush is a species of passerine bird in the family Formicariidae. It is found in Central America from Honduras through Panama, on Trinidad, and in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.
The collared trogon is a near passerine bird in family Trogonidae, the quetzals and trogons. It is found in Mexico, throughout Central America, and in northern South America.
The blue-throated toucanet is a near-passerine bird in the toucan family Ramphastidae. It is found in Costa Rica, Panama and far northwestern Colombia.
The long-billed hermit is a bird in the family Trochilidae, the hummingbirds. It is found from central Mexico south through Central America, Colombia and Ecuador into Peru.
The wrenthrush or zeledonia, is a unique species of nine-primaried oscine, endemic to the Talamancan montane forests.
The blue-black grosbeak is a species of songbird in the family Cardinalidae.
The maroon-chested ground dove is a species of bird in the family Columbidae. It is found in Bolivia, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Panama, Peru, and Venezuela.
Amaurospiza is a genus of seed-eating birds in the cardinal family Cardinalidae that are found in Central and South America.
The blackish-blue seedeater is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in Argentina, Brazil, and Paraguay.
The tawny-throated leaftosser is a tropical American bird species in subfamily Sclerurinae, the leaftossers and miners, of the ovenbird family Furnariidae. It is also known as the Middle American leaftosser and less frequently as tawny-throated leafscraper, Mexican leaftosser or Mexican leafscraper. It is found from Mexico to Panama.
Cabanis's spinetail is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Brazil, Bolivia, and Peru.
Cabanis's wren is a species of bird in the family Troglodytidae. It is found in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua.
The gartered trogon, also known as the northern violaceous trogon, is a bird in the family Trogonidae, the quetzals and trogons. It is found in Mexico, all of Central America, and Colombia, Ecuador, Peru, and Venezuela.
The vermiculated screech owl, is a subspecies of Middle American screech owl, or possibly separate species of owl in the family Strigidae. It is found in Costa Rica, Nicaragua, and Panama.
The isthmian wren is a species of bird in the family Troglodytidae. It is found in Costa Rica and Panama.
The Amazonian grosbeak or Rothschild's grosbeak is a species of grosbeak in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in much of the Amazon Basin, in Bolivia, Brazil, Colombia, French Guiana, Guyana, Peru, Suriname, and Venezuela.
The Ecuadorian seedeater is a species of bird in the cardinal family Cardinalidae that the International Ornithological Committee (IOC) accepted as a species in 2015. It is found in the Andes in southwestern Colombia through Ecuador to northern Peru.
