>>2036252Yeah gators definitely chirp and also croak.
>>2036251They're really not especially dangerous, though I wouldn't swim around them. But in general if you get too close (in a boat) they simply swim off. They're not really interested in you unless you're near their young or something.
pic related is Caddo Lake, not my pic but being up early when there's still fog on the water is haunting and beautiful.
