Living in South Florida for about a year and a half now I've become pretty accustomed to seeing alligators since I spend a good time wandering around in the Everglades. I've become pretty good at spotting them as they float with just a bit of their head above water and keep my eyes open as I approach water to take pictures.
One thing that was a surprise to me was seeing a couple unusually active gators while visiting Corkscrew Swamp Sanctuary. Corkscrew is a National Audubon Society sanctuary that I like to visit periodically and a place everyone should visit. The most unexpected behavior I witnessed was an alligator lifting its head out of the water and growling! Apparently the growl, as I call it, is referred to more formally as a bellow. I suspected it was related to the time of year when alligators are looking to mate and I was right. Gators growl when they feel threatened and want to be left alone and when they’re looking for a mate.
