With luck
About 10% of wildlife watchers report a Lesser Yellowlegs sighting in El Impenetrable National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 180th most-seen of the 219 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.
November
In that month about 20% of wildlife watchers report a Lesser Yellowlegs in El Impenetrable National Park on a given day, against under 5% in January–February and April–September, the lowest months. That is one of El Impenetrable National Park's wettest months, with about 120 mm of rain against 25 mm in July. December has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lesser 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.
18th of 55
Of the 55 parks where we can rate Lesser Yellowlegs sightings, El Impenetrable National Park ranks 18th at about 10%. The best odds are in Merritt Island National Wildlife Refuge (United States, about 30%), Wood Buffalo National Park (Canada, about 30%) and Celestún Biosphere Reserve (Mexico, about 20%).
Same genus: Tringa
The closest relatives of the Lesser Yellowlegs that you can see in El Impenetrable National Park (genus Tringa, Shanks, Tattlers, and Allies) are Solitary Sandpiper (about 10%) and Greater Yellowlegs (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Yellowlegs is recorded against all the birds logged in El Impenetrable National Park (17 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.
