I wasn't able to get a picture of these birds, nor even see colors, etc. because they were brightly backlit. The birds were perched in a nearby tree and the noise got my attention. Sounded like the rapid chirping of pine siskins & goldfinches fighting over the niger sock, only different (yes, I know, great discription!). There were about a dozen of the birds and they took off in flight just as I got a glimpse of them. About the size of a large sparrow. The impression I got was of a titmouse, but NE Colorado is quite a distance out of their range. Listening online to the sound of their voice it could be possible if multiplied several times. Any other bird they could possibly be that I should look at?
Thanks for any and all suggestions - Vicki
