Colloquial term referring to a moose. Moose often browse in swamps and marshes, eating the tender water plants, hence the swamp reference.
The donkey part comes from the fact that they are an animal that is both tough and stubborn.
The man was well-prepared to spend a day in the forest, as he was confident that he would get to photograph a swamp donkey in its natural habitat.

a swamp donkey is unlike any other of the female species. She sits by herself at bars, clubs, anywhere men might become entirely too intoxicated to remember that they pointed her out in the beginning as a dirty butt her all . She is not only ugly as hell,but huge, disgusting, and abnormally confident. Not only will she send you a beer but the bitch will steal your wallet the next day. Stay away they are the devil in true form.
