Rare
Under 5% of wildlife watchers report a Lesser Ground-Cuckoo sighting in Carara National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 333rd most-seen of the 414 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lesser Ground-Cuckoo in Carara National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lesser Ground-Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 10
Of the 10 parks where we can rate Lesser Ground-Cuckoo sightings, Carara National Park ranks 9th at under 5%. The best odds are in Rincón de la Vieja National Park (Costa Rica, about 30%), Cañón del Sumidero National Park (Mexico, about 10%) and Palo Verde National Park (Costa Rica, about 10%).
Same family: Cuculidae

GBIF citizen-science records
It is estimated from how often the Lesser Ground-Cuckoo is recorded against all the birds logged in Carara National Park (46 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.
