He placed it with all the other hummingbirds in the genus Trochilus. He coined the binomial name Trochilus rufus.

The type locality given by Gmelin was Nootka Sound on the west coast of Vancouver Island in western Canada. However, breeding was estimated to occur in northwestern North America and wintering in westcentral Mexico. The rufous hummingbird is now placed with eight other species in the genus Selasphorus that was introduced in 1832 by the English naturalist William Swainson. The genus name combines the Ancient Greek selas meaning... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous Hummingbird sighting in Salt Lake City on a given day, based on 279 verified sightings from GBIF citizen-science data. It is the 105th most-seen of the 216 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Rufous Hummingbird in Salt Lake City on a given day, against under 5% in October to July, the lowest months. That is one of Salt Lake City's driest months, with about 25 mm of rain against 70 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Rufous Hummingbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 25
Of the 25 cities where we can rate Rufous Hummingbird sightings, Salt Lake City ranks 12th at under 5%. The best odds are in Vancouver (Canada, about 10%), Toluca (México, about 10%) and Seattle (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Rufous Hummingbird is recorded against all the birds logged in Salt Lake City (279 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.
