Harris's sparrow (Zonotrichia querula) is a large sparrow. Their breeding habitat is the north part of central Canada (primarily the Northwest Territories and Nunavut, ranging slightly into northern Manitoba and Saskatchewan), making it Canada's only endemic breeding bird. In the winter they migrate to the Great Plains states of the United States, from southern South Dakota to central Texas. The common name of this species commemorates the American amateur ornithologist Edward Harris (1799–1863).
This species is the largest of the sparrows in the family Passerellidae, though other superficially dissimilar species in the family may slightly exceed them in size. They range in total length from 17 to 20 cm (6.7 to 7.9 in), with a 27 cm (11 in) wingspan and weigh from 26 to 49 g (0.92 to 1.73 oz). Among standard measurements, the wing chord is 7.7 to 9.2 cm (3.0 to 3.6 in), the tail is 7.6 to 8.8 cm (3.0 to 3.5 in), the bill is 1.1 to 1.4 cm (0.43 to 0.55 in) and the tarsus is 2.2 to 2.5 cm (0.87 to 0.98 in).
This is a very distinctive looking species. Breeding plumage birds have conspicuous pink bills and black on the crown, face, throat and upper breast, contrasting... Wikipedia →

Rare
Under 5% of wildlife watchers report a Harris's Sparrow sighting in San Francisco on a given day, based on 385 verified sightings from GBIF citizen-science data. It is the 237th most-seen of the 375 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 Harris's Sparrow in San Francisco on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Harris's Sparrow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 15 cities where we can rate Harris's Sparrow sightings, San Francisco ranks 10th at under 5%, level with the leaders once rounded. The best odds are in Tijuana (México, under 5%), Dallas (United States, under 5%) and Vancouver (Canada, under 5%).
Same genus: Zonotrichia

GBIF citizen-science records
It is estimated from how often the Harris's Sparrow is recorded against all the birds logged in San Francisco (385 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.
