Habitat loss due to the removal of forests for logging, agriculture, mining, etc., and capture of birds for the illegal international cage-bird trade are the major factors influencing the population decline of this species.This study uses intraecclesiastical conflict in the Audiencia of Quito as a vehicle for exploring the relationship between migration and political change from approximately 1534 to 1700. The birds are recognized as “Near Threatened” by the IUCN. The small range of the species makes the birds highly susceptible to threats posed by human activities. They are reported to migrate to the lower slopes during winter in groups of about 25 birds. Fruits constitute the majority of the diet of these birds. The length of the birds vary between 46 and 51 cm and their weight ranges from 275 to 355 g. The range of the birds extends from southwest Colombia to central Ecuador. The typical altitude of their habitat ranges between 1,200 to 3,2000 meters and occasionally they might be spotted at elevations as low as 300 meters. They prefer habitats that have a rich growth of mosses and bromeliads. The Andigena laminirostris is found in the mountains of the Andes where they live in the humid montane forests of the mountainous landscape. Plate-billed Mountain Toucan A plate-billed mountain toucan. The birds are often observed in the tree canopies foraging in pairs or in small family groups. The throat of the bird is white in color. nigrirostris, has a completely black beak. There are three subspecies of this bird of which only the nominate subspecies, the A. The range of this species of bird extends all the way from Venezuela south through Colombia and Ecuador to northern Peru. The Andigena nigrirostris is a mountain toucan that lives in the humid forests in the highlands of the Andes. They are often observed foraging with other groups of birds like tanagers, thrushes, etc. The birds live high on the trees but also come to ground at the base of the trees for foraging. The rest of the body is brown colored and is separated from the black colored head by a gray collar. A thumbprint shaped marking is also present at the base of the beak. The birds can be easily distinguished by their colorful beaks which are colored differently at the top (red and black) and the base (yellow-green). The range of the latter begins in eastern Ecuador and extends up to central Peru. The former ranges from central Colombia to eastern Ecuador. The range of this species includes Colombia, Ecuador, and Peru.
