I have been seeing a Cerulean the last few days at our farm. I was hoping that the first pictures were an orange crowned. We have a nesting pair of yellow warblers - this on looked a little different to me.
We have a pair of nesting Red Tailed Hawks on our farm and the bird in #2 was not very pleased with the bird in #1 if that helps. They flew off over the hill before I could get closer for better photos.
