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 →

With luck
About 10% of wildlife watchers report a Rufous Hummingbird sighting in Toluca on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 66th most-seen of the 118 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 60% of wildlife watchers report a Rufous Hummingbird in Toluca on a given day, against under 5% in February–March and November, the lowest months. That is one of Toluca's wettest months, with about 150 mm of rain against 5 mm in December.

GBIF citizen-science records
It is estimated from how often the Rufous Hummingbird is recorded against all the birds logged in Toluca (24 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.
