The red-shouldered hawk (Buteo lineatus) is a medium-sized buteo. Its breeding range spans eastern North America, along the coast of California and northern to northeastern-central Mexico. It is a permanent resident throughout most of its range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation.
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.

Possible
About 30% of wildlife watchers report a Red-shouldered Hawk sighting in San Francisco on a given day, based on 28,293 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 375 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.
September
In that month about 40% of wildlife watchers report a Red-shouldered Hawk in San Francisco on a given day, against about 20% in January–February, May–July and November, the lowest months. That is one of San Francisco's driest months, with almost no rain against 110 mm in December.
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.
8th of 29
Of the 29 cities where we can rate Red-shouldered Hawk sightings, San Francisco ranks 8th at about 30%. 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 San Francisco (28,293 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.
