The grey-breasted mountain toucan (Andigena hypoglauca) is a species of bird in the family Ramphastidae found in humid highland forest, often at the tops of the trees, in the Andes of southern Colombia, Ecuador and Peru. It remains locally fairly common, but has declined due to habitat loss.[1]
Taxonomy and systematics
The grey-breasted mountain toucan was originally described in the genus Pteroglossus.
Subspecies
Two subspecies are recognized:[2]
- A. h. hypoglauca - (Gould, 1833): Found from central Colombia to eastern Ecuador
- A. h. lateralis - Chapman, 1923: Found in eastern Ecuador and central Peru
Description
This species is distinguished from other mountain toucans by its colorful bill: red and black at the tip and yellow-green at the base, where there is a black, thumbprint-shaped mark. The black head is set off from the chestnut-brown back by a pale grey collar. the northern nominate subspecies has dark eyes, while the southern A. h. lateralis has pale eyes. The total length of the grey-breasted mountain toucan is 46–48 cm (18–19 in) long, and the weight is 244-370 grams (8.6–13.1 oz).
Behaviour and ecology
A wide variety of fruits and berries are eaten and this species is often more willing than most largeish toucans to leave the canopy to eat raspberries near the base of the trees. They tend to remain quiet while flying and are known to mix often with other birds while foraging, including larger species of tanagers, thrushes, and icterids, both behavior unusual in toucans. Very little is known about the life history details for this species.
