What specific time frame suggests that observed Wood Ducks are likely nesting hens nearby due to homing instinct?

Answer

April and August

Distinguishing between migratory stopovers and established local breeding is vital for effective habitat management, especially concerning nest box implementation. A practical observational threshold exists based on the strong homing instinct displayed by nesting hens. If Wood Ducks are observed within the continental window spanning from April through August, it is highly probable that nesting hens are actively occupying a nearby area, utilizing their natal site. Since males follow these established females, sightings during this late spring/summer window strongly indicate that the surveyed habitat is part of the established breeding grounds, whereas sightings between October through February usually point toward wintering migrants from further north.
