The thick-billed siskin (Spinus crassirostris) is a species of finch in the family Fringillidae. Found in Argentina, Bolivia, Chile, and Peru, its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude shrubland.
The thick-billed siskin has an adult length of between 13.5 and 14 centimetres (5.3 and 5.5 in). The bill often has a silvery base and is noticeable thicker than other related siskins. The male closely resembles the hooded siskin (Spinus magellanicus) and has a black head and throat, greenish-yellow upper parts (sometimes streaked with dark markings) and bright yellow underparts. It differs from the hooded siskin in having a whitish-grey midbelly. The immature male has a black head but is otherwise less conspicuous than the mature male, being more greyish-olive above and greyish below. The female is similar but lacks the black head and is altogether much duller in appearance, more greyish-olive, with paler underparts. [2]
This bird of the high Andes ranges from western Peru and central Chile to northwestern Argentina. Its altitudinal range is 3,000 to 4,000 metres (10,000 to 13,000 ft) in the northern part of its range but descends to 2,100 metres (7,000 ft) further south. Typical habitat is Polylepis woodland and open country with scrub. [2]
S. crassirostris is an uncommon species with a patchy distribution within its range. However, it has a very wide range and the population seems stable so the International Union for Conservation of Nature has rated it as being a least-concern species. [1]
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 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 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 thick-billed vireo is a small songbird. It breeds in the West Indies in the Bahamas, Turks and Caicos Islands, Cayman Islands, Tortuga Island in Haiti and on cays off the coast of Cuba. It occasionally can be found as a vagrant to south Florida in the United States. The subspecies V. c. approximans of Providencia Island is sometimes treated as a subspecies of the mangrove vireo or as a separate species, the Providencia vireo.
The Rwenzori double-collared sunbird, also called Stuhlmann's sunbird or the Rwanda double-collared sunbird, is a species of bird in the family Nectariniidae. It is found in the Ruwenzori range of mountains in south central Africa. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It is sometimes considered to be a subspecies of the greater double-collared sunbird. Some authors consider this bird to be part of a species complex with Cinnyris afer, where it joins Ludwig's double-collared sunbird and Prigogine's double-collared sunbird. As with other closely related species, each inhabiting different locations, there are subtle similarities and differences between the local populations, and their taxonomic treatment depends on the views of the taxonomist.

The name siskin when referring to a bird is derived from an adaptation of the German dialect words sisschen, zeischen, which are diminutive forms of Middle High German (zîsec) and Middle Low German words, which are themselves apparently of Slavic origin. The name siskin was first recorded in written English in 1562, referring to the Eurasian siskin, Spinus spinus.
