FLOCK

Synonyms: flock¹, herd, drove², pack¹, gang¹, brood These nouns denote a number of animals, birds, or fish considered collectively, and some have human connotations. 

Flock is applied to a congregation of animals of one kind, especially sheep or goats herded by people, and to any congregation of wild or domesticated birds, especially when on the ground. It is also applicable to people who form the membership of a church or to people under someone's care or supervision. 

Herd is used of a number of animals, especially cattle, herded by people; or of wild animals such as antelope, elephants, and zebras; or of whales and seals. Applied to people, it is used disparagingly of a crowd or of the masses and suggests the gregarious aspect of crowd psychology. 

Drove is used of a herd or flock, as of cattle or geese, that is being moved or driven from one place to another; less often it refers to a crowd of people in movement. 

Pack is applicable to any body of animals, especially wolves, or of birds, especially grouse, and to a body of hounds trained to hunt as a unit. It also refers disparagingly to a band or group of persons.  

Gang refers to a herd, especially of buffalo or elk; to a pack of wolves or wild dogs; or to various associations of persons, especially when engaged in violent or criminal pursuits.
