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 →

Rare
Under 5% of wildlife watchers report a Horned Grebe sighting in New York City on a given day, based on 2,767 verified sightings from GBIF citizen-science data. It is the 173rd most-seen of the 359 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
January and February
In those months about 10% of wildlife watchers report a Horned Grebe in New York City on a given day, against under 5% in March to December, the lowest months.
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.
23rd of 44
Of the 44 cities where we can rate Horned Grebe sightings, New York City ranks 23rd at under 5%. The best odds are in Seattle (United States, about 10%), San Francisco (United States, about 10%) and Vancouver (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Horned Grebe is recorded against all the birds logged in New York City (2,767 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.
