Spinus spinus · Irish: Siscín
A small, streaky yellow-green finch with a sharp black cap.
Habitat: Conifer woodland, and increasingly garden feeders in late winter and spring. | Season: All year
An acrobatic feeder, often hanging upside-down like a tit; garden numbers swell in late winter when natural seed supplies run low.
Siskins bred mainly in Ireland's native pinewoods for centuries, but the spread of conifer plantations in the 20th century gave them far more habitat, helping their numbers grow substantially.
