If this is the first stick, the proposal, he is either courting the prettiest girl in the swamp, or just not taking any chances.
He took his time flying by, he was almost getting tangled in his small tree. Finally he did land in a near by tree but I could not see how it went. This tree had maybe 4 – 5 couples nesting. The males made trips as long as I was there. One stick at a time. I think this is going to take a little while.
