I was watching an Inspector Lindley recently where they mentioned that a group of apes together is a "shrewdness", which piqued my curiosity to find this page that discusses those names. Some of my favorites:
A sleuth of bears.
A obstinacy of buffalo.
A clutter of cats.
A peep of chicks.
A business of ferrets.
A skulk of foxes.
A charm of hummingbirds.
An exaltation of larks.
A labor of moles.
A mischief of mice.
A watch of nightingales.
A romp of otters.
A parliament of owls.
A gaze of raccoons.
A surfeit of skunks.
A descent of woodpeckers.
