The red siskin (Spinus cucullatus) is a small endangered finch.
It is native to tropical South America - in northern Colombia, northern Venezuela (where it is called the "cardenalito") and Guyana. [1] It was common in the early 20th century, occurring throughout the foothills of northern Venezuela, but has now become extremely rare in a fragmented range. The population on Trinidad is believed to be extirpated, with no sightings since 1960. An introduced population derived from escaped cagebirds in Puerto Rico has since thought to become extinct.
The red siskin is about 10 cm long. The male is mainly deep red, with black on the head, throat, flight feathers and tail tip, and a whitish lower belly and under tail. The female is grey on the head, breast, and upper parts, apart from a red rump and upper tail. The breast is grey with reddish flanks, and the rest of the underparts, the wings and tail resemble the corresponding areas of the male. Immature females are paler than the adults, and immature males are brown rather than red.
The call is a high-pitched chitter and sharp chi-tit like the Indian silverbill, and the male's song is a musical goldfinch-like melody with twitters and trills.
The red siskin is found in open country, forest edges and grassland with trees or shrubs. The female is believed to lay three greenish-white eggs in a grassy cup nest in a tree. Red siskins eat seeds and are highly gregarious. When they were more numerous, they formed semi-nomadic flocks.
This siskin has been illegally trapped for the cage bird trade [3] and endangered by environmental factors. Domestication has probably been responsible for the continuation of the species, which might otherwise be extinct. This is an attractive finch with a pleasant song, and its unique coloration for a small finch has led to it being used for interbreeding with domestic canaries to produce varieties with red in the plumage.
The red siskin is listed as endangered by the IUCN Red List and nationally critically endangered in Venezuela. It is listed on CITES Appendix I. The greatest threat to the species has been intense illegal trapping for the bird trade since the 1940s, however the species also faces extensive habitat loss. Some hope has been given to this highly endangered species by the discovery in 2003 of a population of several thousand birds in southern Guyana, 1000 km from any previously known colony. Otherwise, the world population is believed to be between 600–6,000 pairs.
Researchers at the Smithsonian Conservation Biology Institute lead a program, the Red Siskin Initiative, with the goals of uncovering more about this species and preventing its extinction. [4] The National Aviary in Pittsburgh, PA has a captive breeding program for the species. [5]
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 violaceous euphonia is a small passerine bird in the true finch family. It is a resident breeder from Trinidad, Tobago and eastern Venezuela south to Paraguay and northeastern Argentina. The bird's range in northern Brazil is the lower portion of the Amazon Basin and the adjacent Tocantins River drainage, with its northwestern limits from Brazil and the Guyanas, the eastern banks of the Orinoco River drainage in central Venezuela.
The red-breasted meadowlark is a passerine bird in the New World family Icteridae. It was formerly named red-breasted blackbird but is not closely related to the red-winged blackbird group.
The grassland yellow finch is a small passerine bird. Despite its name, it is not a finch, but is a seedeater. These were formerly united with the buntings and American sparrows in the Emberizidae, but are now known to be tanagers.
The lesser goldfinch is a small finch in the genus Spinus native to the Americas.
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. According to phylogenetic studies Spinus notatus is its parental ancestor.
The hooded siskin 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.
The star finch is a seed-eating bird species found in northern Australia. It has a distinctive red face and bill, and broad white spots down its flanks. One of its three subspecies may be extinct.
The Fiji parrotfinch is a species of estrildid finch endemic to Fiji that was formerly considered to be a subspecies of the red-headed parrotfinch. This parrotfinch is a small, mainly green bird with a red head and tail and a stubby dark grey bill. It is found in both forested and open habitats, and has adapted well to man-made environments such as grasslands, pasture and gardens. Pairs have a courtship display in which they fly above the trees in an undulating flight, calling constantly. Breeding birds build a domed grass nest with a side entrance, and lay a clutch normally of four white eggs. Newly hatched chicks are naked and pink, with blue balls at the upper and lower corners of the gape, and black markings inside the mouth; older fledglings resemble the adults, but lack the red head colouring. The Fiji parrotfinch eats seeds, especially of grasses, and also readily feeds on insects and nectar. It forms small flocks of up to six birds after the breeding season.
The tricoloured munia is an estrildid finch, native to Bangladesh, India, Sri Lanka, Pakistan, and southern China. The species has also been introduced to the Caribbean, in Trinidad, Jamaica, Hispaniola, Puerto Rico, Cuba, and Venezuela. This species, like the chestnut munia has been known as the black-headed munia. Immature birds have pale brown upperparts, lack the dark head found in adults, and have uniform buff underparts that can be confused with immatures of other munias such as the scaly-breasted munia.
The Cape siskin is a small passerine bird in the finch family. It is an endemic resident breeder in the southern Cape Province of South Africa.
The Drakensberg siskin is a small passerine bird in the finch family. It is an endemic resident breeder in the eastern Cape Province Transkei and western Natal in South Africa, and in Lesotho.
The black siskin is a species of finch in the family Fringillidae. It is found in Argentina, Bolivia, Chile, and Peru. Its natural habitats are subtropical or tropical high-altitude shrubland and subtropical or tropical high-altitude grassland. According to some phylogenetic studies, Spinus notata is its parental ancestor.

The Trinidad euphonia is a species of bird in the family Fringillidae. It is common in northern Colombia and northern Venezuela and uncommon to rare on the Caribbean island of Trinidad. Like all euphonias, it is small, stocky, and short-tailed; unlike some, it is sexually dimorphic. The male is glossy blue-black on the head, back, throat, and upper breast, with a bright yellow forehead and crown, and bright yellow underparts. The female is olive-green above and yellow-olive below, with a grayer patch running down the center of her breast and abdomen, and bright yellow undertail coverts. Its calls are high-pitched, plaintive whistles: the two most common are a single-pitched, double-noted "pee pee" or "tee dee", or a rising, double-noted "puwee", "cooleee" or "duu dee". Its song is a short, jumbled mix of musical and nonmusical notes.
