Researchers: Expanding migration of South American Whistling Ducks in Louisiana could threaten native species

The State of Louisiana is known as a major wintering location for North American waterfowl. However, a new visitor — a species of Whistling Ducks hailing from South America — may pose a problem to native species.

The State of Louisiana is known as a major wintering location for North American waterfowl. However, a new visitor may pose a problem. LSU Ag Center reporter Craig Gautreaux brings us more on the whistling duck.

There are eight species of whistling ducks in the world, all of which are native to areas in North America or South America.

Researchers worry this northward expansion of this particular South American species’ migration area will create a competition for resources that could pose a threat to waterfowl native to the region. That is why they are studying the birds now to determine if any precautionary steps need to be taken.
