How has the Western bluebird adupted life from an egg?

The Western bluebird, like other birds, begins its life as an egg, where it develops through incubation provided by the parents. Once hatched, the chicks are altricial, meaning they are born helpless and require extensive care. The parents feed them a diet of insects and fruits, helping them grow rapidly. As they mature, fledglings learn to fly and forage, gradually adapting to their environment and becoming independent.
