A Prickle of Porcupines

Just like humans, many animals, reptiles and insects enjoy a group or family home; and each of these groups has an identifiable name -- some more than one.  While a group of prairie dogs live in a colony or town, in a convocation is where an eagle can be found.  It's a streak of tigers and a bale of turtles, a labor of moles and a dray or scurry of squirrels.
