The yellow-bellied seedeater (Sporophila nigricollis) is a species of bird in the family Thraupidae, formerly placed with the American sparrows in the Emberizidae.
Taxonomy and systematics
[edit]Hooded seedeater
[edit]The hooded seedeater was a proposed bird species described by Austrian ornithologist August von Pelzeln as Spermophila melanops in 1870. The only known individual was heavily moulted and caught in October 1823 from a flock of other seedeater species at the edge of a lake 15 kilometres north of Registro do Araguaia, Brazil. It is now considered to be either a hybrid or an abnormal specimen of the yellow-bellied seedeater. The bird had a black crest and throat, the upperparts were olive and the underparts showed a dingy buff. In contrast, a typical yellow-bellied seedeater has pale yellow underparts and the black colouring extends to the upper breast.
Distribution and habitat
[edit]The yellow-bellied seedeater is found in Central and South America from Costa Rica to Bolivia. Its natural habitats are subtropical or tropical high-altitude shrubland, pastureland, and heavily degraded former forest.
Threats
[edit]One study in Brazil, estimated that 16,800 yellow-bellied seedeaters are illegally caught and sold as pets annually.[2]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
