Rare
Under 5% of wildlife watchers report a Golden-browed Warbler sighting in Celaque National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 170th most-seen of the 193 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and July
In those months about 10% of wildlife watchers report a Golden-browed Warbler in Celaque National Park on a given day, against under 5% in February–June and August–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Golden-browed Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Golden-browed Warbler sightings, Celaque National Park ranks 3rd at under 5%. The best odds are in Reserva de la Biosfera Mariposa Monarca (Mexico, about 30%) and El Triunfo (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Golden-browed Warbler is recorded against all the birds logged in Celaque National Park (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.
