The species is sometimes called simply the hawk owl; however, many species of owls in the genus Ninox are also called "hawk owls".
The northern hawk-owl was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Strix ulula.

The genus name is of unknown etymology and may simply have been invented by Duméril. The specific epithet ulula is Latin for a "screech owl".
A molecular phylogenetic study of the owls published in 2019 found that the northern... Wikipedia →

Possible
About 20% of wildlife watchers report a Northern Hawk Owl sighting in Wood Buffalo National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 59 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 50% of wildlife watchers report a Northern Hawk Owl in Wood Buffalo National Park on a given day, against under 5% in May and August–September, the lowest months. March and December have too few records to rate.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Northern Hawk Owl sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 6
Of the 6 parks where we can rate Northern Hawk Owl sightings, Wood Buffalo National Park ranks 2nd at about 20%. The best odds are in Kluane National Park (Canada, about 30%).
GBIF citizen-science records
It is estimated from how often the Northern Hawk Owl is recorded against all the birds logged in Wood Buffalo National Park (6 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.
