Here is a video showing two species of birds: the Tufted Titmouse and the Purple Finch. The Purple Finch exhibits what is known as sexual dimorphism, which means the males and females have distinguishable differences in plumage. As in most songbirds, the male Purple Finch is the more colorful of the two, with the female being more of a buffy brown with no raspberry purple coloration.
Here is a video showing multiple bird species eating on a suet cake in my front yard. The species you will see, as well as the times they first appear in the video is as follows:

Here is a video of Purple Finches, American Goldfinches (male, female, and juvenile) in winter plumage, and a Carolina Chickadee. This video was taken in the month of January, thus the winter goldfinch plumage.
This is a video showing a female cardinal who is soon overtaken by a mob of Mourning Doves. Notice the aggressive behavior that is displayed when trying to defend one's spot or displace another from theirs.
