It makes Keel which is boat shaped that reduces friction in flight and flight muscles are attached to it.
Like all other birds wrens have powerful breast muscles that aid flight.

If I'm understanding the question correctly, then birds have a number of ways that their bodies have adapted to allow for flight. Some of these would include hollow bones, an enlarged breast bone, rigid skeleton, beaks instead of jaws (less heavy than jaws), and feathers (allows for a more streamlined body). Flying takes a great deal of energy, which means that birds have a very high metabolism. This leads to a great deal of their time not flying spent eating in an attempt to get enough energy to allow for more flight.
In order to maintain the rigidness necessary for flight the birds collar bones have fused together making a "wishbone" of sorts. The rigidness and hollowness of the bones make flight easier on the bird.
Penguins do not have skeletons that are identical to humans certain things are different such as bone length and the presence of a tail in the penguin. But certain structures are referred to as homologous. example: the flipper in the penguin and the arm and hand of a human have the same bone structure just different bone lengths.
The flight feathers are the feathers located on the wings and tail. There are primary flight feathers that on the bird would be equivalent to our hand. A bird also has secondary flight feathers which when comparing to a human would be our forearm. If you unfold the wing of a bird you will see the flight feathers.
Does public aid pay for breast reductions?
it helps them fly because their bones are lighter and its easier to fly with light bones. But birds with dense bones, such as penguins makes it impossible for them to fly
There really isn't a wishbone (furculum) on a human. The equivalent would be if our clavicles (collarbones) were fused with our sternum.On a bird they are fused for support to aid flight.

Many experts consider reconstruction to be an integral component of the therapy for breast cancer. A naturally appearing breast offers a sense of wholeness and normalcy, which can aid in the psychological recovery from breast cancer.
An animal that has feathers and is warm-blooded is called a bird. Birds are characterized by their feathers, beaks, and lightweight skeletons, which aid in flight. They are also endothermic, meaning they can regulate their body temperature independently of their environment. Examples of birds include sparrows, eagles, and penguins.
