Hi all,
I have been over run with Pine Siskins, at my feeders since 12/26/2018. I have not had these numbers for years. It is interesting since I am 2, blocks north of Denver County. The birds also feed on the seeds of my native Rabbitbrush [Chrysothamnus naueosus].
They are also feeding on seeds of my native perennials. Two thistle feeders are not enough food for them.
Enjoy them when you have them.
Happy Birding!
