Rare
Under 5% of wildlife watchers report a Buff-bellied Hummingbird sighting in Tikal National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 218th most-seen of the 300 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a Buff-bellied Hummingbird in Tikal National Park on a given day, against under 5% in March to January, the lowest months. That is one of Tikal National Park's driest months, with about 30 mm of rain against 190 mm in June.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Buff-bellied 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.

Of the 7 parks where we can rate Buff-bellied Hummingbird sightings, Tikal National Park ranks 6th at under 5%. The best odds are in Cañón del Sumidero National Park (Mexico, about 20%), Sian Ka'an Biosphere Reserve (Mexico, about 20%) and Calakmul Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Buff-bellied Hummingbird is recorded against all the birds logged in Tikal National Park (30 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.
