What is a group of deer called?

A group of deer is commonly called a herd. The size of a deer herd can vary greatly depending on the species, the habitat, and the time of year. Some herds might only consist of a few deer, while others can number in the dozens or even hundreds, especially during the winter months when deer tend to congregate for safety and to share resources. The social%20structure within a deer herd is often hierarchical, with dominant individuals having priority access to food and mates. Deer herds offer protection from predators, as there are more eyes and ears to detect danger. However, large herds can also lead to increased competition for food and can contribute to overgrazing in certain areas.
