We had a nest nearby this season and now the young, having seen them separately on and off since fledging are now visiting the yard together. A male and a female as the size difference is dramatic, the male being smaller. They are chasing all sorts of birds here. This morning chasing a Red-eyed vireo. Unsuccessful.
