Siskins in Alder

They’re noisy, tiny, green and yellow, and at the top of a tree. The Siskins, Carduelis spinus, are here.

There’s a large flock in the Alder trees and all sorts of complex behaviours are being exhibited. I can see one bird feeding another, presumably as part of pair bonding, and others reacting to food perch availability.

They are a delight.
