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 Rio de Janeiro on a given day, based on 382 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July to May
In those months about 10% of wildlife watchers report a Smooth-billed Ani in Rio de Janeiro on a given day, against under 5% in June, the lowest month.
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.
23rd of 34
Of the 34 cities where we can rate Smooth-billed Ani sightings, Rio de Janeiro ranks 23rd at about 10%. The best odds are in Fortaleza (Brazil, about 50%), Natal (Brazil, about 50%) and Santa Cruz de la Sierra (Bolivia, about 40%).
GBIF citizen-science records
It is estimated from how often the Smooth-billed Ani is recorded against all the birds logged in Rio de Janeiro (382 verified sightings), 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.
