Austral parakeet

The Austral parakeet, scientifically known as Enicognathus ferrugineus, is a distinctive parrot species recognized as the southernmost parrot in the world. Its range extends across Argentina and Chile, with possible occurrences in the Falkland Islands. This species is a member of the Psittacidae family, which includes African and New World parrots, and shares its genus, Enicognathus, with the slender-billed parakeet.

Description and Appearance

Adult Austral parakeets typically measure between 28 to 36 cm in length. Their plumage is predominantly green, with a yellowish-green face, upperparts, and underparts. Notable markings include a dull reddish forehead and lores, a dull reddish patch on the belly, and a dull reddish tail. The edges of their feathers are dark, giving them a scaly appearance. The wings are mostly green with bluish-green primaries. Immature birds exhibit similar coloration but with less intense red hues. The subspecies E. f. minor is distinguished by being smaller and darker than the nominate subspecies.

Distribution and Habitat

The Austral parakeet inhabits the southern regions of South America, with subspecies E. f. minor found from the O'Higgins Region of Chile southward into southwestern Argentina. The nominate subspecies' range extends further south, approaching Cape Horn. They are primarily found in southern beech (Nothofagus) forests and woodlands, often co-occurring with oaks (Quercus) and Drimys andina. Their habitat also includes nearby semi-open areas, ranchlands, and occasionally agricultural zones. While typically found near sea level in the far south, they can range as high as 2,000 meters in the northern parts of their distribution.

Behavior and Diet

These parakeets are social creatures, frequently observed foraging in flocks that can comprise up to 100 individuals, sometimes mixed with other bird species. Their diet is varied, consisting of seeds from grasses, bamboo, and the Chilean pine (Araucaria araucana), along with fruits, berries, acorns, and leaf buds. In the northernmost parts of their range in Argentina, they have also been documented feeding on insect larvae.

Breeding and Vocalization

The breeding season for the Austral parakeet is not precisely defined but includes December. They typically nest in tree cavities, showing a preference for those found in large dead oak trees. There are also reports of them constructing twig nests within bamboo thickets. The clutch size usually ranges from five to eight eggs, with an incubation period of approximately 26 days observed in captivity. Their vocalizations are characterized by a nasal grating note, often repeated in long series, interspersed with a more drawn-out, higher-pitched "kreeh" call.

Conservation Status

The Austral parakeet is currently assessed as 'Least Concern' by the International Union for Conservation of Nature (IUCN). This classification is based on its extensive geographic range and an estimated stable population. No immediate threats to the species have been identified, and much of its habitat is protected within national parks, contributing to its common presence throughout its range.
