Summary Introduction

To explain: The adaptations that help birds to reduce their body weight to enable flight.

Introduction: The birds have adapted to be aerodynamically favorable to fly. They have learned through the evolutions that how changes in structure can enable them to adapt to a certain environment. The adaptations in flight help migratory birds like albatross to travel thousands of kilometers whereas different flight mechanisms are present in hummingbird and eagle.
