I believe so. I haven’t seen mergansers in the wild. They aren’t real popular in my area. We have more of the dabbler/puddle ducks. I believe mergansers are more of a diving duck (they dive under the water to hunt for their food and typically live near deeper bodies of water vs rivers and streams).
