All are wonderful, with great detail in the whites and shadows and lovely BGs! The last one makes me smile, wondering what his wife said when he dumped it on the doorstep. That crest is very cool – I don’t think I’ve ever seen one like that.
Another nice series of flight shots, Allen. While seeing the crest is interesting, the first one is my favorite. I like the wing position of the first over the second, and the branch obscures less of the bird compared to the third and fourth.
