Hooded Merganser x Common Merganser Hybrid

Hooded Merganser x Common Merganser Hybrid

Spotted
This interesting hybrid occurs between two distinct North American merganser species, the small, crested Hooded Merganser and the larger Common Merganser. Hybrids can display an intriguing blend of features, particularly concerning crest shape and bill structure.
Where to spot
Look in freshwater habitats across North America where both parent species coexist, such as wooded ponds, small lakes, slow-moving rivers, and wetlands, especially during migration or winter.
How to spot
Pay close attention to the bill, looking for a shape that is not quite as slender as a Common Merganser's but not as short and thick as a Hooded Merganser's. The head crest, body size, and white patches should also be examined for intermediate characteristics.
When to spot
Best chances are during fall and spring migration or in wintering areas where these species frequently associate. Breeding season observations are less common as hybrids are often sterile.
A hybrid might exhibit a crest that is intermediate in size and shape between the prominent fan-like hood of the Hooded Merganser and the more shaggy crest of the female Common Merganser.
