You’ve probably heard of a school of fish, a pack of wolves, and a pride of lions. But have you ever come across an army of frogs, a mob of kangaroos, or a prickle of porcupines? Check out the San Diego Zoo’s page of Animal Group Names: http://www.sandiegozoo.org/animalbytes/got_questions_groups_list.html
Here’s another list from the USGS Wildlife Research Center: http://www.npwrc.usgs.gov/about/faqs/animals/names.htm
http://en.wikipedia.org/wiki/List_of_animal_names – Wikipedia has a page of Animal Names that lists their common names; names of males, females, and young animals; and group names (some animals actually have several different group names).
Enchanted Learning has a similar list of male, female, baby, and groups of animals – and their page includes pictures: http://www.enchantedlearning.com/subjects/animals/Animalbabies.shtml
P.S. The lists above remind me of a great book by Ruth Heller titled A Cache of Jewels and Other Collective Nouns, part of a fun language arts picture book series for kids ages 2-8. Most of the collective nouns that the author uses as examples are animal group names, but she also includes other items such as a bunch of bananas, a fleet of ships, a host of angels, and a bouquet of flowers. Ruth Heller’s books are not only highly educational, they are full of beautiful illustrations bursting with color. We have a collection of these books at home and I love reading them – and I’m an adult! But that’s a post for another day!
