The Protection Detail
It almost looks as if these egrets were bodyguards forming a protective shield around the alligator. Did Mr. A tick off some other alligator so he requested protection from these egrets?! If that’s his plan I don’t think it is very well thought out. The egrets will very likely flee immediately at the first sign of any type of physical encounter, especially among alligators.
Or maybe Mr. A is actually the bodyguard protecting the egrets from some particularly grouchy great blue heron? Either way, they all seem to be on high alert, although in this case it makes much more sense for the egrets to be the ones to remain on alert!
