Rare
Under 5% of wildlife watchers report a Greater Yellowlegs sighting in Bastimentos Island National Marine Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 281st most-seen of the 375 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Greater Yellowlegs in Bastimentos Island National Marine Park on a given day, so our monthly data shows no clear season.
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.
47th of 72
Of the 72 parks where we can rate Greater Yellowlegs sightings, Bastimentos Island National Marine Park ranks 47th 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 Bastimentos Island National Marine Park (38 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.
