Welcome to BPN, Julien! Very nice first post. Great to see both male and female birds and their alert poses. I might give it a bit more room at the top or even go for a vertical crop. The whites and legs could go a bit darker for my taste. Keep them coming!
Julien: Above comments notwithstanding, getting male and female, front and back in a single shot is a great feat IMHO. The horizontal comp doesn't bother me as much as the broken branch stub, but it's still a great shot. Well done!
Big welcome to BPN, Julien, very nice first post. You have great depeth of field for 5.6, most probably because the two heads are on the same plane, otherwise you would need a much smaller aperture to render them both reasonably sharp.
I agree with the previous comments.
This is a really neat image and a unique opportunity to get both sides. I like the horizontal composition and the broken branch doesn't bother me. Perhaps tone down the legs on the bird on the left.
