A bird's wing bone
A homologous structure to a human arm bone would be the forelimb bones in other mammals, such as the forelimb bones in a bat or a whale. These structures may have different functions (e.g. for flying or swimming), but they share a common evolutionary origin with the human arm bones.

Yes, the human forelimb is considered a homologous structure because it shares a common evolutionary origin with the forelimbs of other vertebrates. Despite variations in function and appearance, the underlying bone structure and developmental pathways are similar across species.
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
The chicken's wishbone is homologous to the CLAVICLE of a human.

Human bone size and structure are a result of the environment and
more than likely yes, because their bone structures are similar to each other.
