Eurasian siskin (Sẻ thông Siskim, Spinus spinus)
also called the European siskin, common siskin or just siskin. 
Other (archaic) names include black-headed goldfinch, barley bird and aberdevine.

The Eurasian siskin (Spinus spinus) is a small passerine bird in the finch family Fringillidae. 

This bird species can be found across the greater part of Eurosiberia and the north of Africa. 
Its breeding area is separated into two zones, both sides of the Palearctic realm: the eastern coast of Asia and the central and northern part of Europe.

Passeriformes originates from New Latin, combining the Latin passer ("sparrow") and -iformes ("having the form of"). It translates to "sparrow-shaped" or "sparrow-like", referring to the largest order of birds (over 5,000 species) that includes songbirds and perching birds.

Fringillidae is the scientific family name for true finches, derived from New Latin. It stems from the Latin word fringilla (meaning finch or small bird, often associated with the chaffinch) and the suffix -idae, indicating a zoological family. The root fringilla is believed to originate from an Indo-European echoic base relating to a "small bird" or "twittering" sound.

The genus name is from the Ancient Greek spinos, a name for a now-unidentifiable bird.
All of the species in the genus, except for the Tibetan serin, were formerly included in the genus Carduelis. 
The English name is from German dialect sisschen or zeischen.
