The hooded siskin (Spinus magellanicus) is a small passerine bird in the finch family (Fringillidae), native to South America. It belongs to the putative clade of neotropical siskins in the genus Spinus sensu lato.
There are 11 subspecies, including the Santa Cruz hooded siskin (S. m. santaecrucis) of central and eastern Bolivia. This subspecies is sometimes considered to be a separate species.
Hooded siskins are 10 to 14 cm in length. The male is largely green above and yellow below with a black head. It has a narrow yellow collar and a yellow rump. The tail is black with yellow sides to the base and the wings are black with a broad yellow band. Females are duller with a green-brown head, yellow-green breast and sides and a whitish belly.
The twittering song may be uttered from a perch or in flight. It is varied and fast, and may contain imitations of other birds.
It inhabits woodland, savannas, scrubland, farmland, parks and gardens. It occurs from sea-level up to 5000 m. In eastern South America, it is found from central Argentina north to central Brazil. In the Andean region, it occurs from northwestern Argentina and northern Chile north to central Colombia. There is an isolated population in southeastern Venezuela, Guyana and the Brazilian state of Roraima.
It is commonly found in flocks, feeding in trees or bushes or on the ground. The diet consists mainly of seeds together with buds, leaves and some insects. Geophagy has been observed in this species. [2]
The hooded siskin is part of a recent and rapid adaptive radiation of Spinus finches in South America. [3]
Elizabeth Beckman and Christopher Witt demonstrated that birds from the Andes in the northwestern portion of the range were more closely related to the thick-billed siskin (S. crassirostris) and that hooded siskin is therefore polyphyletic and includes at least two species. [3]
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers.
The American goldfinch is a small North American bird in the finch family. It is migratory, ranging from mid-Alberta to North Carolina during the breeding season, and from just south of the Canada–United States border to Mexico during the winter.
The European goldfinch or simply the goldfinch is a small passerine bird in the finch family that is native to Europe, North Africa and western and central Asia. It has been introduced to other areas, including Australia, New Zealand and Uruguay.
The genus Carduelis is a group of birds in the finch family Fringillidae.
The Eurasian siskin is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.
The pine siskin is a North American bird in the finch family. It is a migratory bird with an extremely sporadic winter range.
The citril finch, also known as the Alpine citril finch, is a small songbird, a member of the true finch family, Fringillidae.
The lesser goldfinch is a very small songbird of the Americas. Together with its relatives the American goldfinch and Lawrence's goldfinch, it forms the New World goldfinch clade in the genus Spinus.
Lawrence's goldfinch is a small songbird of erratic distribution that breeds in California and Baja California and winters in the southwestern United States and northern Mexico.
The yellow-bellied siskin is a small passerine bird in the finch family Fringillidae. It breeds from Costa Rica south to southern Ecuador, central Bolivia and the highlands of northwestern Venezuela.
The cardueline finches are a subfamily, Carduelinae, one of three subfamilies of the finch family Fringillidae, the others being the Fringillinae and the Euphoniinae. The Hawaiian honeycreepers are now included in this subfamily. Except for the Hawaiian honeycreepers which underwent adaptive radiation in Hawaii and have evolved a broad range of diets, cardueline finches are specialised seed eaters, and unlike most passerine birds, they feed their young mostly on seeds, which are regurgitated. Besides this, they differ from the other finches in some minor details of their skull. They are adept at opening seeds and clinging to stems, unlike other granivorous birds, such as sparrows and buntings, which feed mostly on fallen seeds. Some members of this subfamily are further specialised to feed on a particular type of seed, such as cones in the case of crossbills. Carduelines forage in flocks throughout the year, rather than keeping territories, and males defend their females rather than a territory or nest.
