Likely
About 50% of wildlife watchers report a Lesser Greenlet sighting in Santa Rosa National Park on a given day, based on 315 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 233 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January and June
In those months about 60% of wildlife watchers report a Lesser Greenlet in Santa Rosa National Park on a given day, against about 40% in February–May, September and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lesser Greenlet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 44
Of the 44 parks where we can rate Lesser Greenlet sightings, Santa Rosa National Park ranks 6th at about 50%. The best odds are in Pico Bonito National Park (Honduras, about 60%), Tikal National Park (Guatemala, about 60%) and Gandoca-Manzanillo Wildlife Refuge (Costa Rica, about 50%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Lesser Greenlet is recorded against all the birds logged in Santa Rosa National Park (315 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.
