Rare
Under 5% of wildlife watchers report a Greater Yellowlegs sighting in Yasuní National Park on a given day, based on 126 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 283rd most-seen of the 533 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and August–November
In those months about 10% of wildlife watchers report a Greater Yellowlegs in Yasuní National Park on a given day, against under 5% in March–July and December–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Greater Yellowlegs sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
33rd of 72
Of the 72 parks where we can rate Greater Yellowlegs sightings, Yasuní National Park ranks 33rd at under 5%. The best odds are in Katmai National Park (United States, about 60%), El Vizcaíno Biosphere Reserve (Mexico, about 40%) and Merritt Island National Wildlife Refuge (United States, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Greater Yellowlegs is recorded against all the birds logged in Yasuní National Park (126 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.
