The deer was the biggest surprise. I never gave a thought to what they sounded like. I am sure in the past I have thought I heard owls when hearing doves- hopefully I'll know better from now on.
The fox was little creepy.
I have seen an owl a couple of times: once in the jungles of Ecuador (pictured below) and once, a great horned owl, in the woods behind our house in Cherry Hill NJ. I tried to imitate the call of the great horned owl and, likely by coincidence, it flew closer.
