The red of a male House Finch (top photo) comes from pigments in its food during molt, so the more pigment in the food, the redder the male. Once House Finches find your bird feeders, they will bring along a lot of friends and be the most frequent visitors.  They will also eat seeds that have fallen to the ground. Females prefer to mate with the reddest male they can find, perhaps raising the chances they get a capable mate who can do his part in feeding the nestlings.
