Titmice and chickadees are heavily represented, because the feeder has been specifically decked out to attract and accommodate them. Safflower is the primary constituent of the seed with a pinch of sunflower hearts and just a few peanuts. The coffee can lid keeps larger birds out, for the most part. (The neighborhood cardinals have figured out how to perch briefly underneath in order to nab a seed or two at a time.) I'm shooting through a single pane of glass which degrades the image sharpness.
