Guys, gals,
This is just my point. Who REALLY needs to know, for real-life situations, rather than pub trivia nights, WHAT a group of something is called, other than a 'group' or 'bunch' or 'whole lot of' of course.
I'm not gonna start a campaign to do away with collective nouns or anything. They just seem unnecessary.
I am completely flumoxed as to what expletive could be used to describe Giraffes.

Probably a good one though!
I just looked it up. Marty's correct. A whole bunch of penguins is a 'colony'.
But that set me to cogetatin' - at what point does a few or some or many of something, garner their semi-official mantle? Become whatever preposterous 'kolectiv' somebody made-up for them during the 19th century?
Less is more in this instance I feel. So I'm taking the easy road and using group, herd, flock, 'a bunch of', and 'some', inter-changably for all animals as, honest-to-God, life's too short to worry about such nonsense.
Anyway. It's a "Nausea" of Politicians, I think.
