Pearly parakeet

The pearly parakeet (Pyrrhura lepida), also recognized in aviculture as the pearly conure, is a distinct species of parrot native to Brazil. It belongs to the subfamily Arinae within the family Psittacidae, which encompasses African and New World parrots.

Description and Appearance

Measuring approximately 24 to 25 cm (9.4 to 9.8 inches) in length and weighing between 70 to 80 g (2.5 to 2.8 oz), the pearly parakeet exhibits a visually appealing plumage. Adults typically display a dark brown crown and buff ear coverts, with the face being a dull blue-green. A notable characteristic is the whitish bare skin encircling the eye. The upperparts are predominantly green with a bluish tint. The upper breast and neck sides are adorned with brown featuring buff scaling, which contributes to the species' 'pearly' namesake, and the breast itself has a blue tinge. The remaining underparts are green with a blue wash. The wings are largely green, distinguished by black and cobalt blue primaries and red underwing coverts. The tail is reddish-brown on its upper surface and blackish-brown underneath. Adult irises are dark brown, bills are brownish-black, and legs are slate-black. Immature birds share similarities with adults. There are recognized subspecies, including P. l. lepida, P. l. anerythra, and P. l. coerulescens, which show variations in head coloration, throat and breast shades, and the presence of red on the breast, belly, and wings.

Distribution and Habitat

The pearly parakeet's natural range is confined to north-central Brazil. The nominate subspecies is found in the northeastern states of Pará and northwestern Maranhão. Subspecies P. l. coerulescens inhabits eastern Pará, specifically between the Xingu and Tocantins rivers, while P. l. anerythra is found in central and northeastern Maranhão, with occasional sightings in Mato Grosso. The species thrives in the interior and at the edges of humid terra firme forests, as well as in secondary forests and sometimes in clearings situated near forested areas.

Behavior and Diet

Information regarding the pearly parakeet's movements is not well-documented. Its diet is known to include fruits, though further specifics about its feeding habits are limited. Similarly, its breeding biology remains largely unknown, with no specific details recorded about its reproductive cycles or behaviors.

Vocalizations

The calls of the pearly parakeet are described as having a rather grating quality, typically delivered in rapid sequences such as "krree krree krree" or "krek krek krek." These vocalizations are made both when perched and in flight, though perched birds are often observed to be silent. When in flocks, they communicate frequently and simultaneously, producing a noisy, harsh, and piercing chattering sound.

Conservation Status

The pearly parakeet has undergone several assessments by the IUCN. It was initially classified as Threatened, later moved to Near Threatened in 2004, and has been listed as Vulnerable since 2012. The species faces significant threats due to its limited geographic range and an unknown population size that is believed to be in decline. The primary threat identified is the loss of its habitat, as large tracts of lowland forests within its range have been severely altered or completely cleared. While the species is present in several protected areas, many of these sites are impacted by illegal logging activities, further jeopardizing its survival.
