With the arrival of the first cold weather, siskins (Carduelis spinus) arrive in our territory from northern Europe, a species of songbird from the Fringilliade family, very similar to siskins but with a much thinner beak.
With yellowish-brown plumage, they present sexual dimorphism, where males have a black spot on their heads, while lighter-looking females have more striped chests.
With a wingspan that sometimes exceeds 20 cm, it is a fairly small bird, measuring between 11 and 12.5 cm in length. It weighs between 10 and 18 gr.
It is a granivorous species and its flight is fast and undulating.
They usually go in groups where they often mix with greenfinches, greenfinches and finches.
