Modern birds, or neornithine birds, exhibit features such as a lightweight skeleton, advanced respiratory systems, and a high metabolic rate, allowing for efficient flight and diverse ecological adaptations. In contrast, ancient birds, like Archaeopteryx, possessed characteristics of both dinosaurs and modern birds, including teeth, long bony tails, and feathers that were not exclusively for flight. Additionally, many ancient birds had a different ecological role and morphology, reflecting their evolution during the Mesozoic era. Overall, modern birds show greater specialization and diversity compared to their ancient counterparts.
