The white-tailed jackrabbit (Lepus townsendii), also known as the prairie hare and the white jack, is a species of hare found in western North America. Like all hares and rabbits, it is a member of the family Leporidae of order Lagomorpha. It is a solitary individual except where several males court a female in the breeding season. Litters of four to five young are born in a form, a shallow depression in the ground, hidden among vegetation. This jackrabbit has two described subspecies: L. townsendii townsendii occurring west of the Rocky Mountains and L. townsendii campanius occurring east of the Rocky Mountains.
The white-tailed jackrabbit is a large species of hare and is the largest species called "jackrabbit". This jackrabbit has an adult length of 22 to 26 inches (56 to 65 centimeters), including a tail measuring 2.6 to 4.0 in (6.6 to 10.2 cm), and a weight between 5.5 and 9.5 pounds (2.5 and 4.3 kilograms). From winter to spring, weight tends to increase in females due to pregnancy, but decrease in males due to the stresses of reproductive competition. Thus, females in Iowa went from averaging 7.9 lb (3,600 g) in winter to 8.4 lb (3,800 g) in spring and males... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-tailed Jackrabbit is recorded against all the mammals logged in Edmonton (676 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.
