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 →

With luck
About 10% of wildlife watchers report a Hooded Merganser sighting in Calgary on a given day, based on 2,856 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 259 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a Hooded Merganser in Calgary on a given day, against under 5% in January–February and May, the lowest months. That is one of Calgary's driest months, with about 25 mm of rain against 120 mm in June.
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.
7th of 32
Of the 32 cities where we can rate Hooded Merganser sightings, Calgary ranks 7th at about 10%. The best odds are in Denver (United States, about 20%), Vancouver (Canada, about 20%) and Portland (United States, about 10%).
Same family: Anatidae
The closest relatives of the Hooded Merganser that you can see in Calgary (family Anatidae, Ducks, Geese, and Swans) are Mallard (about 80%), Canada Goose (about 70%) and Common Goldeneye (about 50%), 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 Calgary (2,856 verified sightings), 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.
