The slender-billed parakeet or choroy (Enicognathus leptorhynchus) is a species of bird in subfamily
Taxonomy and systematics
The slender-billed parakeet has also been named Enicognathus byroni, but the current
Description
The slender-billed parakeet is about 40 cm (16 in) long. The species' English name comes from its greatly elongated
Distribution and habitat
The slender-billed parakeet is endemic to central Chile between the Santiago Metropolitan Region and Los Lagos Region; it also occurs in the Aysén Region, but rarely, and has been recorded as a vagrant in Argentina.[3][4][5]
The slender-billed parakeet primarily inhabits southern beech (Nothofagus) and Chilean pine (Araucaria araucana) forest. It also occurs in nearby semi-open areas, ranchlands, and in cultivated areas, all of them usually in winter. In elevation it ranges as high as 2,000 m (6,600 ft).[4]
Behavior
Movement
The slender-billed parakeet moves from the upper elevations to lower ones in the austral winter months of May through September.[4]
Feeding
The slender-billed parakeet's year-round diet includes seeds of grass and thistle, buds, and berries. In autumn the seeds of Araucaria are a major component; it appears that its unusual bill is adapted to feed on them. Seeds of Nothofagus are also important at other times of the year. It is a serious agricultural pest on Chiloé Island.[4]
Breeding
The slender-billed parakeet breeds between November and February. It usually nests in tree cavities and is known to add twigs to raise a deep cavities's floor. Often several pairs will nest in the same tree. It also occasionally uses rock crevices and has been recorded making a twig nest in bamboo. At least one nest held 10 eggs but they were suspected of being laid by two females; another nest held five eggs. The incubation period is about 26 to 28 days and fledging occurs about 42 to 45 days after hatch.[4]
Vocalization
The slender-billed parakeet's most common call is "a nasal grating note, typically repeated in long series, e.g. “grrreh-grrreh-grrreh...”." It also makes "higher-pitched slightly more melodious screeches, “kreeh!” or “kerreh!”."[4]
