The groove-billed toucanet (Aulacorhynchus sulcatus) is a near-passerine bird in the toucan family Ramphastidae. It is found in Colombia and Venezuela. The groove-billed toucanet was originally described in the genus Pteroglossus. The International Ornithological Committee (IOC), the South American Classification Committee of the American Ornithological Society, and the Clements taxonomy recognize these three subspecies:
BirdLife International's Handbook of the Birds of the World retains it as a species. Subspecies A. s. erythrognathus might warrant consideration as a separate species because its voice is different from that of the other two subspecies.
The groove-billed toucanet is 33 to 37 cm (13 to 15 in) long and weighs 130 to 200 g (4.6 to 7.1 oz). Its grooved culmen and mandible give it its English name. Wikipedia →

Possible
About 30% of wildlife watchers report a Groove-billed Toucanet sighting in Henri Pittier National Park on a given day, based on 259 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 358 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Groove-billed Toucanet is recorded against all the birds logged in Henri Pittier National Park (259 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.
