Mottled Duck Mystery

Leave a comment

The mottled duck has always had a soft spot in my heart.

They are a native duck of the Gulf Coast and always symbolized the brackish-intermediate wetland I love so much.

Growing up on the Gulf Coast of Southeast Texas they were a common sight of my youth and then sometime in my twenties they started to dwindle.

Now there are restrictive bag limits for hunters and much study of this beautiful but under appreciated waterfowl. The waterfowl conservation community has spent much time studying these species in the last 10 years and while looking over various studies one particular tidbit caught my attention.

The Anahuac National Wildlife Refuge began outfitting mottled ducks with transmitters to track their movements in the mid 2000s. And according to refuge officials there have been some surprising results.

The results indicate that mottled ducks, which normally avoid open water, have begun spending extended time offshore in the Gulf of Mexico. Scientists suspect habitat loss and saltwater intrusion, both a result of coastal development, may be forcing the ducks out of their wetland habitats. Coastal research in other regions shows similar trends, indicating the problem may be more than just local.

The idea of a puddle duck like the mottled duck in the open waters of the Gulf seems strange indeed but the fact is there is still much to learn about this species but this study goes to show why it is important to learn about wildlife habitat and movements.

Without that knowledge managing species is impossible and with the continual growing pressure on our wildlife resources, good management is more important than ever.
