It has a wingspan of 18 centimetres (7.1 in). Of the hummingbirds found in the United States, Rivoli's hummingbird is one... Wikipedia →

Likely
About 40% of wildlife watchers report a Rivoli's Hummingbird sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 78 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March and November
In those months about 50% of wildlife watchers report a Rivoli's Hummingbird in Reserva de la Biosfera Mariposa Monarca on a given day, against about 20% in May and October, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 40 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Rivoli's 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.

GBIF citizen-science records
It is estimated from how often the Rivoli's Hummingbird is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (78 verified sightings from 2019 to 2026), 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.
