The choice of what feathers swallows choose, and how they reflect local conditions, is another interesting path! Given the size of the feather I observed, and the way the mix of fields/lawns and river's edge at Croton Point Park attracts Canada Geese, I'd guess that goose down might be a popular nest-liner there.
