The rufous hummingbird (Selasphorus rufus) is a small hummingbird, about 8 cm (3 in) long with a long, straight and slender bill.

He placed it with all the other hummingbirds in the genus Trochilus. He coined the binomial name Trochilus rufus. Gmelin based his description on the ruff-necked hummingbird described by John Latham in 1782 and the ruffed honeysucker described by Thomas Pennant in 1785.
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 Portland on a given day, based on 1,608 verified sightings from GBIF citizen-science data. It is the 95th most-seen of the 230 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and July–September
In those months about 10% of wildlife watchers report a Rufous Hummingbird in Portland on a given day, against under 5% in May–June and October–March, the lowest months. Those are among Portland's driest months, with about 50 mm of rain a month against 250 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.
4th of 25
Of the 25 cities where we can rate Rufous Hummingbird sightings, Portland ranks 4th 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 Portland (1,608 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.
