Question

Quizplus · Accepted Answer

Birds have a relatively weak sense of smell compared to other senses such as sight and hearing. This is because their olfactory bulbs, the structures in the brain responsible for processing odor information, are small and relatively undeveloped. In contrast, birds have highly developed visual systems that allow them to navigate through complex environments and identify food sources. Additionally, birds have efficient systems for gas exchange and thermoregulation that are well-adapted for their high metabolic rates and active lifestyles. Flight is also a highly developed trait in birds, with adaptations such as lightweight bones, powerful muscles, and specialized feathers allowing for efficient aerial locomotion.
