Linda, your pictures are really wonderful! I think the cowbirds are pretty and I love the one of that fat chick! I can only imagine what another bird thinks when a cowbird egg hatches in it's nest. It amazes me that they will feed a baby other than their own but I guess since the egg was left in their nest and they incubated it, it is kinda their own ... even if it is three times the size of their babies!
Love that Titmouse too!
