This American Black Duck was looking to start a fight with me. ( Ha Ha) The truth is I took this photo as the duck was flopping its wings, it created a cool effect of one tough duck. Photos like these always makes me smile.
Interesting Fact: If a mother is killed or separated from her brood, another Black Duck with ducklings of her own, regardless of their age, will quickly adopt the orphans. ( http://identify.whatbird.com/obj/392/_/American_Black_Duck.aspx )
