Siskins are small, acrobatic finches, often seen in flocks with other species. The overall impression is of yellow and black stripes, but the males have brighter yellow colours and solid black crowns, while females are duller with fine stripes on the head. Perched birds show a yellow stripe or bar across the shoulder, which helps to distinguish them from the larger Greenfinches, which have a yellow stripe down the edge of the folded wing.
You'll spot them on hanging feeders and bird tables feasting on sunflower hearts and nyger seed. For more information on nyger seed products.
