Really, animals seem to have a sense for natural stuff - I'd probably follow the snakes and turtles.
Soon to be followed by a "herd of birds".
It's a "bed" or "den" of snakes when they're hibernating or breeding, but when they're on the move it is a "slither of snakes". Turtles are always a "bale of turtles".
I knew that odd little book An Exaltation of Larks would come in handy some day.
