Since the juveniles have fledged most of the Great Egret activity at my favorite swamp has been on the far side of the big pond. The water is a little shallower for hunting and I expect harbors a lot of fish. The Alligators, of course, go all over. I didn’t see this one in the Egret’s reflection until I was processing my images.
The distance is too far for really sharp images, but some days that’s all you see. The Great Egret wisely kept moving and then flew over a juvenile Little Blue Heron.
He finally touched down with a flourish surrounded by lush green swamp vegetation.
On a recent visit to one of the local wildlife management areas several Alligators were bellowing all around the old rice field pond. Both males and females can bellow and will do it year round, not just in mating season. During mating season they will do it as a chorus. Needless to say, it can be a little disconcerting. You the human have no way to know what a particular chorus is all about and sound echoing on the water often makes it hard to know just where a particular Alligator is hiding.
I watched this Alligator work his way along the bank of the dike and unfortunately couldn’t see his whole body but was fascinated by the jumping water. The “water dance” is caused by an infrasonic signal known as “subaudible vibrations” and is only performed by males.
After this performance he was done with his socialization activities.
He picked a spot a little further along the bank and settled in.
Alligator social behavior is quite complex, and include at least visual, auditory, and olfactory components. I found a fascinating article by Kent A. Vliet published in the journal American Zoology and shared by the St. Augustine Alligator Farm Zoological Park.
These two Alligators were swimming in different ponds, taken about an hour apart on a recent June morning.
The bank where I was standing was much higher above the water in the second image, the sun was higher in the sky, and there was a remarkable difference in how the water appeared. The second Alligator was moving a little faster, too.
Alligators follow their instincts when they hear a splash in the water…lets go check it out.
An Anhinga had jumped into the pond and was swimming with his head up. First one then two Alligators were in hot pursuit.
I was too far away to really see what was happening. In fact I probably shouldn’t have bothered with these images with the glare on the water, but it was like watching a train wreck. I’m not sure if this churning of the water was the two Alligators having a spat or if the bird had ducked under and the gators lunged.
The Alligators backed away a bit then the Anhinga popped up between them then leisurely swam along as if he were alone. A minute or two later they all lost interest and went their separate ways.
