Contract and relax to enable movements and flight.
Mitochondria are also found abundantly in the flight muscle cells of insects and birds to generate energy for its movement and flight.

Mainly flying insects, which are caught in flight.
the function of a tail is to lift its body and to increase the speed of flight
The most important flight muscles are the pectorals, which correspond to the muscles of your chest :)
After the pectoralis major, the next most important muscle in the birds is triceps. It is highly developed muscle in birds and used to extend the wings.
humming birds are small in size
An analogous organ is a structure in different species that serves the same function but does not share a common evolutionary origin. For example, the wings of birds and insects are analogous organs as they both serve the function of flight but evolved independently.
Traits that perform a similar function but arise from different ancestral traits are called analogous traits. An example of analogous traits are the wings of birds and insects, which have different ancestral origins but serve the same function of flight.
Flight (n) [...] 2. a group of creatures or objects flying together, in particular: a flock or large body of birds or insects in the air, esp. when migrating.
The most important flight muscle in a bird is the pectoralis muscle. This large muscle is responsible for the powerful downstroke of the wings during flight, enabling birds to lift off and maintain altitude. Additionally, the supracoracoideus muscle, located beneath the pectoralis, assists in the upstroke of the wings, allowing for more efficient and controlled flight. Together, these muscles are crucial for a bird's ability to fly effectively.
Besides birds, other groups of animals that fly include insects (such as bees, butterflies, and dragonflies), bats, and some species of fish (like flying fish). These animals have adapted unique anatomical features and behaviors that allow them to move through the air.
