There were about four of these flitting around. I liked how it looked in the dogwood (yeah, needs to have the dead wood trimmed out of it).
Larry said it isn't a cardinal because it has no crest. He said it is a scarlet tanager. I looked up scarlet tanager online and it has a black wing.
He looked it up in the bird book and it turns out it isn't a scarlet tanager, it's a summer tanager. It is a little smaller than a cardinal with no crest, but the same intense red. Larry says it is just passing through.
