Rare
Under 5% of wildlife watchers report a White-bellied Wren sighting in Celestún Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 267th most-seen of the 297 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-bellied Wren in Celestún Biosphere Reserve on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-bellied Wren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate White-bellied Wren sightings, Celestún Biosphere Reserve ranks 6th at under 5%. The best odds are in Calakmul Biosphere Reserve (Mexico, about 30%), Tikal National Park (Guatemala, about 30%) and Montes Azules Biosphere Reserve (Mexico, about 10%).
Same family: Troglodytidae
The closest relatives of the White-bellied Wren that you can see in Celestún Biosphere Reserve (family Troglodytidae, Wrens) are Yucatán Wren (about 40%) and Southern House Wren (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-bellied Wren is recorded against all the birds logged in Celestún Biosphere Reserve (8 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.
