The grey partridge (Perdix perdix) is a bird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. The scientific name is the Latin for "partridge". The grey partridge was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Tetrao perdix. Linnaeus specified the type locality as Europe but this has been restricted to Sweden. The word perdix is Latin meaning "partridge", from Ancient Greek περδιξ/perdix meaning "partridge". The grey partridge together with the Daurian partridge and the Tibetan partridge are now placed in the genus Perdix that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson.
Eight subspecies are recognised by the IOC World Bird List, though the differences are clinal, and not all are accepted by other authorities; the HBW/BirdLife International list only accepts six subspecies; the differences noted below:

Rare
Under 5% of wildlife watchers report a Gray Partridge sighting in Calgary on a given day, based on 976 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 259 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Gray Partridge in Calgary on a given day, so our monthly data shows no clear season.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Gray Partridge sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 14
Of the 14 cities where we can rate Gray Partridge sightings, Calgary ranks 6th at under 5%. The best odds are in Sincan (Turkey, about 10%), Novosibirsk (Russia, about 10%) and Edmonton (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Gray Partridge is recorded against all the birds logged in Calgary (976 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.
