Browne wrote that the smooth-billed anis "live chiefly upon ticks and other small vermin; and may be frequently seen jumping about all cows and oxen in the fields".

With luck
About 10% of wildlife watchers report a Smooth-billed Ani sighting in Manuel Antonio National Park on a given day, based on 128 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 107th most-seen of the 325 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Smooth-billed Ani in Manuel Antonio National Park on a given day, against under 5% in June, August and October–February, the lowest months. That is one of Manuel Antonio National Park's wettest months, with about 660 mm of rain against 35 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Smooth-billed Ani sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
35th of 50
Of the 50 parks where we can rate Smooth-billed Ani sightings, Manuel Antonio National Park ranks 35th at about 10%. The best odds are in Parque Estadual Encontro das Águas (Brazil, about 70%), Galápagos Islands (Ecuador, about 50%) and Caroni Swamp (Trinidad and Tobago, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Smooth-billed Ani is recorded against all the birds logged in Manuel Antonio National Park (128 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.
