(noun) The branch of zoology and natural history that involves the study of birds. Ornithology studies frequently include classifying or identifying bird species and studying behavior, reproduction, migration patterns, population growth, conservation and bird ecology.
Ornithologists are the scientists who practice ornithology. Their methods may include field observations, tracking or banding birds, studying captive or rehabilitated birds and using radar or satellite equipment to monitor birds’ habitat and migration. Many amateur birders contribute to the study of ornithology through organized, structured bird watching and count events.
