Many of our birds show up in twos and threes, but only the Goldfinches show up in flocks. They may be small, but when they show up, they take over the feeders. All three of them. I took a few pictures.
There were a lot more Goldfinches but they kept taking off and landing with some little bits of airtime confrontations. They were in the trees, on the rail, and on the reverse side of the feeders where I can’t take pictures.
