I live in northern Sweden and see a lot of jackdaws here. There seems to be quite a variation in sizes among them, so I'm interested to know if the smaller ones could be younger?
It's only early spring, so no hatchlings yet. I just assumed that a bird over a year old would be full-grown, but perhaps it takes longer than that. Are there any experts here who can shed some light on the subject?
