\"Eurasian siskin,\" Wikipedia, the free encyclopedia. The Siskin is a small, short-tailed bird, 11–12.5 centimetres (4.3–4.9 in) in length with a wingspan that ranges from 20–23 centimetres (7.9–9.1 in).It weighs between 10–18 grams (0.35–0.63 oz)The bird\'s appearance shows sexual dimorphism. The male has a greyish green back; yellow rump; the sides of the tail are yellow and the end is black; the wings are black with a distinctive yellow wing stripe; its breast is yellowish becoming whiter and striped towards the cloaca; it has a black bib (or chin patch) and on its head it has two yellow auriculas and a black cap.The amount of black on the bib is very variable between males and the size of the bib has been related to dominance within a flock.The plumage of the female is more olive-coloured than the male. The cap and the auriculas are greenish with a white bib and a rump that is a slightly striped whitish yellow.The young have a similar colouration to the females, with drab colours and a more subdued plumage.
