Spinus spinus

Tiny13 gForest

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 to 23 centimetres (7.9 to 9.1 in). It weighs between 12 and 18 grams (0.42 and 0.63 oz). The bird shows sexual dimorphism. The male has a greyish-green back, a yellow rump, yellow sides to the tail with a black tip, black wings with a distinctive yellow wing stripe, a yellowish breast that becomes whiter and striped towards the cloaca, a black bib (or chin patch) and two yellow auriculas and a black cap on its head. Voice: This bird has two calls, both powerful but conflicting, one is descending and the other is ascending, their onomatopoeic sounds can be represented as "tilu" and "tluih". On occasions they also issue a harsh rattling chirrup. Like other finches, the song is a smooth, rapid twitter and trill of long duration, occasionally interrupted by stronger or shorter syllables.

In both sexes, total length can range from 11–14 cm (4.3–5.5 in), with a wingspan of 18–22 cm (7.1–8.7 in) and a weight of 12–18 g (0.42–0.63 oz). Adults are brown on the upperparts and pale on the underparts, with heavy streaking throughout. They have short, forked tails. Their bills are conical like most finches but are more elongated and slender than those of other co-occurring finches.
