I notice that there are quite a few options for the collective nouns depending on the part of the world you are in so some are quite different to our perceived norms.
I found the following
A glaring of cats A rhumba of rattlesnakes An army of caterpillars A nest of rhumours (not actually an animal admittedly) A gang of elks A family of sardines A huddle of walruses A bed of clams A shiver of sharks A Crash of Rhinoceroses A Horde of Hamsters A Kindle of Kittens a roll of armadillos a candle of anteaters a congregation of alligators a sleuth of bears a flutter of butterflies a train of camels a coalition of cheetahs a cast of crabs a congregation of crocodiles a cry of dogs (hounds)
and my personal favourite:
A bike of bees
