How is the North American range of the Wood Duck effectively divided for biologists regarding breeding populations?

Answer

Into two major, largely separate breeding populations: East and West

When discussing where Wood Ducks are found, a crucial biological distinction must be made concerning their breeding distribution across the continent. The overall range, which spans from southern Canada down to Cuba, is effectively segmented into two principal, geographically separated breeding populations. These two groups are designated as the Eastern population and the Western population. This separation is significant because the two groups may have differing migratory habits or habitat reliance, requiring distinct conservation approaches.
