Possible
About 30% of wildlife watchers report a Blue Bunting sighting in Calakmul Biosphere Reserve on a given day, based on 303 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a Blue Bunting in Calakmul Biosphere Reserve on a given day, against about 20% in January and August, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blue Bunting 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 6 parks where we can rate Blue Bunting sightings, Calakmul Biosphere Reserve has the highest daily chance: about 30%. Next come Sian Ka'an Biosphere Reserve (Mexico, about 20%) and Tikal National Park (Guatemala, about 20%).
GBIF citizen-science records
It is estimated from how often the Blue Bunting is recorded against all the birds logged in Calakmul Biosphere Reserve (303 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.
