The term "hen hawk" refers to a bird of prey that feeds primarily on small animals such as rodents, birds, and insects. Synonyms for this bird include "cooper's hawk," which is a medium-sized hawk known for its agility and quick movements, and "sharp-shinned hawk," which is a smaller species known for its sharp talons and fast flight. Other related terms include "sparrow hawk," "kestrel," and "merlin," which are all small falcons that prey on small birds and insects. Each of these birds has unique features and behaviors that make them distinct, but they all share a common hunting technique of swooping down on their prey from above with great speed and accuracy.
