Andigena laminirostris

Andigena laminirostris, known as the plate-billed mountain toucan, is native to the humid montane forests of the western Andes in northern Ecuador and southwestern Colombia. Its range lies mostly between 4,300 and 8,200 feet in elevation, where it prefers dense, mossy cloud forests with high humidity and a continuous canopy. It is not found outside its natural range and is highly dependent on primary forest habitats for nesting and feeding. Within its range, it is typically observed alone, in pairs, or small family groups, often active at mid to upper canopy levels. Although occasionally seen near forest edges or partially disturbed zones, it avoids open habitats and does not inhabit urban or agricultural areas. Deforestation, road building, and habitat fragmentation have significantly reduced its viable habitat, contributing to its classification as Near Threatened on the IUCN Red List. The global population is estimated at fewer than 10,000 mature individuals, and the population trend is decreasing.

This species measures approximately 16 to 17 inches in length and is easily recognized by its distinctively patterned bill, which is pale yellow near the base and bordered by a black ridge along the upper mandible. The body is a combination of slate-blue and olive, with a black crown, a chestnut vent, and a vivid yellow patch under the tail. A bold red patch on the rump and turquoise-blue on the chest distinguish it further from other toucans in the region. It is primarily frugivorous but also consumes insects, small reptiles, and bird eggs. It plays an important ecological role as a seed disperser in its habitat. Vocalizations include series of loud, frog-like croaks and mechanical rattles produced during social interactions, territory defense, or pair bonding. The nesting season typically spans from March through July, with nesting cavities located in tree trunks, often reused across seasons. Photographed in the western Andes of Ecuador.
