It seems like "bunch" is becoming the collective noun for everything these days. Bunch of people, bunch of bananas, bunch of stuff. How sad when the English language is filled with so many interesting collective nouns. I think that some of the most descriptive and entertaining collective nouns are for animals which you'll meet on safari in southern Africa. Here are a whole bunch of them to whet your appetite:

Baboons – Troop or Congress
Bats – Cloud
Buffaloes – Obstinacy
Cheetahs – Coalition
Crocodiles – Bask
Elephants – Herd, Parade or Memory
Giraffes – Journey
Hippos – Raft or Pod
Hyenas – Clan or Cackle
Leopards – Leap
Lions – Pride
Lizards - Lounge
Monkeys – Shrewdness or troop
Mongoose - Business
Owls – Parliament
Porcupines – Prickle
Rhinos - Crash

Weasels - Sneak
Wildebeest - Implausibility
Zebras – Dazzle or Herd
For many of the animals there are numerous options. I particularly love a dazzle of Zebra, a crash of Rhino and an obstinacy of Buffalo. Choose your favorite or better yet, make one up for fun and post it as a comment below.
