I always found this aspect of English, uniquely naming sets of animals, to be simultaneously adorable and thoroughly useless and anachronistic.
Is there a defence of this flock of birds, mischief of mice, whateverthefuck of whosits system? (Does it have a name?) Do all linguistic systems do it?

Some of the terms vary depending on wieght of numbers (say, more than 12) or behaviour at the time, such as migration.

My speculation anyway. Whole things just seems silly to me.
As a native English speaker, and armchair linguist, I feel that that sentence describes a rather substantial percentage of English usage, grammar, and (especially!) spelling.
That seems unbelievable to me but they just go around happily saying that easily.
