Likely
About 50% of wildlife watchers report a Great-tailed Grackle sighting in Coiba National Park on a given day, based on 108 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 118 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January, September and November
In those months about 60% of wildlife watchers report a Great-tailed Grackle in Coiba National Park on a given day, against about 40% in July–August and December, the lowest months. May and October have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Great-tailed Grackle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 68
Of the 68 parks where we can rate Great-tailed Grackle sightings, Coiba National Park ranks 17th at about 50%. The best odds are in Arrecifes de Cozumel National Park (Mexico, about 80%), Las Baulas Marine National Park (Costa Rica, about 80%) and Sian Ka'an Biosphere Reserve (Mexico, about 80%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Great-tailed Grackle that you can see in Coiba National Park (order Passeriformes, Perching Birds) are Lance-tailed Manakin (about 60%), Bananaquit (about 60%) and Barred Antshrike (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great-tailed Grackle is recorded against all the birds logged in Coiba National Park (108 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.
