When I was in the woods at the Amana Nature Trail on Tuesday I saw and heard several rose-bested grosbeaks. I noticed males engaged in what I thought might be a courtship display. From a branch near the top of the tree the male would fly up vertically and descend nearby. Or might the male(s) be attempting to ward off competition? Any insight into such behavior?
