乔科巨嘴鸟

The Choco Toucan (Ramphastos brevis) is a large, colourful toucan in the family Ramphastidae, endemic to the humid forests of the Chocó biogeographic region along the Pacific slope of Colombia and Ecuador. Toucans are instantly recognisable by their enormous, brightly coloured bills — in this species, the bill is broadly yellow with a dark culmen ridge — which are used for reaching fruit on slender branches, as thermoregulatory organs, and in social and aggressive displays. The Choco Toucan is closely related to the Chestnut-mandibled Toucan and was previously considered conspecific. It inhabits lowland and foothill tropical rainforest, forest edges, and large trees in more open areas, occurring from sea level to approximately 1,200 metres. It feeds primarily on large fruits, supplemented by insects, lizards, small mammals, and the eggs and nestlings of smaller birds. Toucans are important seed dispersers in Neotropical forests, swallowing large seeds that pass through their digestive systems and are deposited at distance from parent trees. The IUCN classifies the Choco Toucan as Least Concern. While extensive deforestation in the Chocó is a long-term concern, the species still occupies a broad range of forested habitats and appears to tolerate some habitat modification.
