Christmas Day a flock of about 15robins visited the crabapple, picking the dried (and probably fermented) fruit.
Usually a few siskins mix in with the goldfinches, but again on Christmas Day we had a flock of siskins with only a couple of goldfinches. What is particularly interesting is the slight red that appears to be a remaining trace of young birds' gape flange. I don't know if this was present on all of the siskins, but it was quite apparent in my photographs of the birds on the sunflower feeder just outside the window - close enough to get that detail. I find this interesting since the siskins nest early, unlike their goldfinch cousins. I would expect this sign of young birds to have faded by now. I'd love to hear from someone who could shed more light for me.
These birds don't feed on the apples, but a flock of 20 waxwings hurried through in search of apple ciderjack in the the fruit.
