A pod, a pride, a murder, a school.

For the linguistically oriented types, the collective nouns listed above apply, in order, to birds, geese, foxes (or vermin or thieves and which I will, from this moment forward, use to refer to hand-knit socks), larks; peacocks, cattle on the move, young birds, quail (or grouse or partridges); whales, lions, crows, fish; geese again, apes, bears, mallards. (Then there's a sounder of boar, a wisp of snipe, a kindle of kittens, a cete of badger, a nide of partridge. I love English.)
