1, 2. Flock, drove, herd, pack refer to a company of animals, often under the care or guidance of someone. Flock is the popular term, which applies to groups of animals, especially of sheep or goats, and companies of birds: This lamb is the choicest of the flock. A flock of wild geese flew overhead. Drove is especially applied to a number of oxen, sheep, or swine when driven in a group: A drove of oxen was taken to market. A large drove of swine filled the roadway. Herd is usually applied to large animals such as cattle, originally meaning those under the charge of someone; but by extension, to other animals feeding or driven together: a buffalo herd; a herd of elephants. Pack applies to a number of animals kept together or keeping together for offense or defense: a pack of hounds kept for hunting; a pack of wolves. As applied to people, drove, herd, and pack carry a contemptuous implication.
