Quick Answer
Common mergansers are larger and more widespread, with a wider, flat bill, while hooded mergansers are smaller, have a distinctive crested head, and a narrower, more pointed bill.
Distinguishing Features
When hunting mergansers, it’s essential to recognize their differences in appearance and behavior. Common mergansers are the more abundant of the two species and are typically found in large groups, often near fish-rich waters. They have a flat, broad bill that’s well-suited for scooping up fish. Hooded mergansers, on the other hand, are smaller and more secretive, often found in smaller groups or alone. They have a distinctive crest on their head, which they can raise and lower at will.
Hunting Techniques
To effectively hunt mergansers, hunters should focus on areas with abundant fish populations, such as rivers, streams, and coastal waters. For common mergansers, a good spotter scope can be useful for locating large groups, while for hooded mergansers, a more stealthy approach may be required to avoid scaring them off. When it comes to shooting, mergansers are relatively fast flyers, so hunters should be prepared to make quick shots at relatively long ranges, often between 20-40 yards.
