However, morphological, hybridization, and DNA studies have confirmed that this arrangement is paraphyletic; New World barbets are more closely related to toucans than they are to Old World barbets. Therefore New World (Capitonidae sensu stricto), African (Lybiidae), and Asian (Megalaimidae) barbets were each accorded their own families.

Rare
Under 5% of wildlife watchers report a Prong-billed Barbet sighting in Arenal Volcano National Park on a given day, based on 453 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 246th most-seen of the 503 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Prong-billed Barbet in Arenal Volcano National Park on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Prong-billed Barbet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 7
Of the 7 parks where we can rate Prong-billed Barbet sightings, Arenal Volcano National Park ranks 7th at under 5%. The best odds are in Poás Volcano National Park (Costa Rica, about 60%), Volcán Barú National Park (Panama, about 30%) and Monteverde Cloud Forest Reserve (Costa Rica, about 20%).

GBIF citizen-science records
It is estimated from how often the Prong-billed Barbet is recorded against all the birds logged in Arenal Volcano National Park (453 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.
