The hooded merganser (Lophodytes cucullatus) is a species of fish-eating duck in the subfamily Anatinae. It is the only extant species in the genus Lophodytes. The genus name derives from Greek: lophos meaning 'crest', and dutes meaning 'diver'. The bird is striking in appearance; both sexes have crests that they can raise or lower, and the breeding plumage of the male is handsomely patterned and colored. The hooded merganser has a sawbill but is not classified as a typical merganser.
Hooded mergansers are the second-smallest species of merganser, with only the smew of Europe and Asia being smaller, and it also is the only merganser whose native habitat is restricted to North America. The hooded merganser was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Mergus cucullatus. Linnaeus based his account on the "round-crested duck" that had been described and illustrated by the English naturalist Mark Catesby in the first volume of his The Natural History of Carolina, Florida and the Bahama Islands that was published between 1729 and 1732. Linnaeus specified the type location as America... Wikipedia →

Rare
Under 5% of wildlife watchers report a Hooded Merganser sighting in Wadden Sea National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 258th most-seen of the 285 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Hooded Merganser in Wadden Sea National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Hooded Merganser sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
31st of 31
Of the 31 parks where we can rate Hooded Merganser sightings, Wadden Sea National Park ranks 31st at under 5%. The best odds are in Merritt Island National Wildlife Refuge (United States, about 10%), Pacific Rim National Park Reserve (Canada, about 10%) and Great Bear Rainforest (Canada, about 10%).
Same family: Anatidae
The closest relatives of the Hooded Merganser that you can see in Wadden Sea National Park (family Anatidae, Ducks, Geese, and Swans) are Mallard (about 60%), Greylag Goose (about 60%) and Common Shelduck (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hooded Merganser is recorded against all the birds logged in Wadden Sea National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
