What is the functions of fore limbs of aves?

The forelimbs of aves, or birds, have evolved primarily into wings, which serve essential functions such as flight, gliding, and maneuvering in the air. They also play a role in thermoregulation, as birds can use their wings to help control body temperature. Additionally, bird wings are involved in courtship displays and can aid in foraging or nesting activities, depending on the species. Overall, the forelimbs are crucial for a bird's survival and reproductive success.
