The horned grebe or Slavonian grebe (Podiceps auritus) is a relatively small and threatened species of waterbird in the family Podicipedidae. The Eurasian subspecies is distributed over most of northern Europe and northern Asia, breeding from Iceland east to the Russian Far East. The North American subspecies spans most of Canada and some of the United States. A small population was cited in Greenland in 1973, but is not mapped or further mentioned by subsequent authors.
The American name 'horned' refers to the orange-yellow crest feathers located above and behind the eyes, called "horns". The English name, originally 'Sclavonian', is first attested by George Montagu in his 1802 Ornithological Dictionary, from Scalovia, an old name for northern Prussia, referring to the species' main breeding area in Europe; the spelling was emended (without any reason given) to the current 'Slavonian' by Hartert in 1912.
The horned grebe was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema... Wikipedia →

No species of the same family or order lives in Katmai National Park, so these are its closest relatives here: other birds.
Rare
Under 5% of wildlife watchers report a Horned Grebe sighting in Katmai National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 80th most-seen of the 93 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Horned Grebe in Katmai National Park on a given day, against under 5% in May–July and September, the lowest months. April and October–February have too few records to rate.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Horned Grebe sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 26
Of the 26 parks where we can rate Horned Grebe sightings, Katmai National Park ranks 11th at under 5%. The best odds are in Pacific Rim National Park Reserve (Canada, about 20%), Great Bear Rainforest (Canada, about 20%) and Elk Island National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Horned Grebe is recorded against all the birds logged in Katmai National Park (7 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.
