A poetic slant on collective nouns. Everyone has heard the phrase a school of fish . But what about a rumba of rattlesnakes, an army of ants , or a crash of rhinos ? Derived from both oral and written traditions, collective nouns go back centuries. These terms not only charm us with their sound, but they provide a bit of insight into animal behavior. Readers can find these and other terms-from alley cats to zebras-in fourteen thought-provoking poems by Marjorie Maddox. She and artist Philip Huber create a wonderful combination of rich wordplay and captivating art that piques the imagination.
