The red-shouldered hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the eagles, hawks and relatives in the genus Falco and coined the binomial name Falco lineatus. Gmelin based his account on the "barred-breasted buzzard" of John Latham and the "red shouldered falcon" of Thomas Pennant. Latham had described a preserved specimen from North America in the Leverian collection while Pennant's specimen formed part of the collection of Anna Blackburne and had come from Long Island. The red-shouldered hawk is now placed with 27 other species in the genus Buteo that was introduced in 1799 by Bernard Germain de Lacépède.

Rare
Under 5% of wildlife watchers report a Red-shouldered Hawk sighting in Philadelphia on a given day, based on 1,165 verified sightings from GBIF citizen-science data. It is the 89th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
October to March
In those months about 10% of wildlife watchers report a Red-shouldered Hawk in Philadelphia on a given day, against under 5% in April to September, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Red-shouldered Hawk sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 29
Of the 29 cities where we can rate Red-shouldered Hawk sightings, Philadelphia ranks 17th at under 5%. The best odds are in Orlando (United States, about 60%), Sacramento (United States, about 40%) and San Antonio (United States, about 40%).
GBIF citizen-science records
It is estimated from how often the Red-shouldered Hawk is recorded against all the birds logged in Philadelphia (1,165 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.
