Many countries, including the United States, provide good waterfowl hunting opportunities.
Seasoned duck hunters often discuss their favorite duck hunting locations. The Chesapeake Bay and southern Louisiana top the list in the US, while to our north Canada most certainly is on the list. We can’t forget Mexico to our south. These locations indeed offer what is considered “Good” duck hunting.

Those who have had the opportunity to travel outside of North America will likely include New Zealand and perhaps even Uruguay.
In friendly discussions and even healthy debates, it would be difficult to argue that any of the locations mentioned are unsuitable for duck hunting.
