The male Cardinal is bright red all over. The female is more a rust color.
This time of year the songbirds are hungry. Putting out a seed feeder is a big help and they will reward you by flocking to the feeder and doing a dance for you. I prefer black sunflower seer, safflower seed, and thistle for the finches. Less desirable birds like starlings, grackles, and sparrows will sometimes push others away from the feeder but hey, they are hungry too.
