Poor cold birdies

Well Yesterday I was questioning if my blue birds managed to get south before the snow. See the answer I got this AM? The remnants of the snow you can still see in the background. Its hard to see the bluebirds in the pic, the blend well but one next to the fence post on the second wire and the one on the top wire is a bit further over. There was also a third bird on a tree, so perhaps these are the babies?
