Possible
About 30% of wildlife watchers report a Lesser Greenlet sighting in Parque Natural Metropolitano on a given day, based on 1,013 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 328 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Lesser Greenlet in Parque Natural Metropolitano on a given day, against about 20% in March–April and July–August, the lowest months. That is one of Parque Natural Metropolitano's driest months, with about 15 mm of rain against 350 mm in July.
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.
20th of 44
Of the 44 parks where we can rate Lesser Greenlet sightings, Parque Natural Metropolitano ranks 20th at about 30%. 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 Parque Natural Metropolitano (1,013 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.
