Please identify this bird

QCould someone ID this bird which I photographed on a feeder with a redpoll? Ron Weeks

AIt’s a female Siskin, as shown by the greenish colouring, streaky plumage and the lack of the black cap which is typical of the male bird. These small finches are often found with redpolls, both in Alders and birches, and on feeders, where both species are fond of black niger seed.
