The short-eared owl (Asio flammeus) is a widespread grassland species in the family Strigidae. Owls belonging to genus Asio are known as the eared owls, as they have tufts of feathers resembling mammalian ears. These "ear" tufts may or may not be visible. The short-eared owl will display its tufts when in a defensive pose, although its very short tufts are usually not visible. The short-eared owl is found in open country and grasslands.
The short-eared owl was formally described in 1763 by the Lutheran bishop Erik Pontoppidan under the binomial name Strix flammea. The specific epithet is from the Latin flammeus meaning "flammulated" or "flame-coloured". This owl is now placed with seven other species in the genus Asio that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. Wikipedia →

Rare
Under 5% of wildlife watchers report a Short-eared Owl sighting in Calgary on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 251st most-seen of the 259 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 Short-eared Owl in Calgary on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Short-eared Owl sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 28 cities where we can rate Short-eared Owl sightings, Calgary ranks 27th at under 5%, level with the leaders once rounded. The best odds are in Bogota (Colombia, under 5%), Vasai-Virar (India, under 5%) and Beijing (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Short-eared Owl is recorded against all the birds logged in Calgary (10 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.
