John James Audubon was an American ornithologist renowned for his primary focus on which group of living beings?

• A. Mammals
• B. Birds
• C. Reptiles
• D. Insects

Answer: (B)

John James Audubon is best known for his work in ornithology, focusing on birds. He devoted his major field studies to North American avifauna and produced detailed paintings and notes, most famously in The Birds of America, that documented bird species, their plumage, behavior, and habitats. This emphasis on birds sets his legacy apart from researchers who work with mammals, reptiles, or insects. So the living beings he studied and celebrated were birds.
