Possible
About 20% of wildlife watchers report a Blue-throated Hummingbird sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 46th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May
In that month about 30% of wildlife watchers report a Blue-throated Hummingbird in Reserva de la Biosfera Mariposa Monarca on a given day, against under 5% in January, the lowest month. April and June–September have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blue-throated Hummingbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Blue-throated Hummingbird sightings, Reserva de la Biosfera Mariposa Monarca has the highest daily chance: about 20%. Next come Cumbres de Monterrey National Park (Mexico, about 20%) and Big Bend National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue-throated Hummingbird is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (28 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.
