According to the U.S. Geological Survey, a group of goats is called a tribe or a trip. Animal congregations often have seemingly odd names that vary by species.
The proper collective noun for a group of goats differs from similar animals. For example, a group of sheep is known as a drove, a flock or a herd. These are fairly recognizable words, but they are not properly applied to tribes of goats. Other mammals have interesting collective nouns, such as a prickle of porcupines, a romp of otters, a bloat of hippopotamuses, a tower of giraffes and a shrewdness of apes.
