The Groove-billed Toucanet, is a near-passerine bird native to Colombia and Venezuela. This species, belonging to the toucan family Ramphastidae, is found in three primary subspecies: A. s. sulcatus in northern Venezuela, A. s. erythrognathus in the mountains of northeastern Venezuela, and A. s. calorhynchus in northeastern Colombia and northwestern Venezuela. These toucanets primarily inhabit humid montane forests but are also found in semi-open landscapes such as secondary forests, forest edges, gardens, and isolated trees. They avoid large open areas and generally range in elevation from sea level to about 7,900 feet, with some movement to lower elevations during the rainy season​​​​​​​​​​. In terms of physical characteristics, the Groove-billed Toucanet measures approximately 13 to 15 inches in length and weighs between 4.6 to 7.1 ounces. The distinct grooved culmen and mandible of its bill inspire its English name. Subspecies exhibit slight variations in bill color and plumage, but all are predominantly green with lighter underparts and yellow undertail coverts. The most notable feature is the wine-red to brown-red bill with a black stripe on the mandible, which varies among subspecies. Additionally, they display bare blue skin around the eyes and varying degrees of gold-bronze on the face​​.
