Pearly Parakeet

Description:

24 cm.. in length and 70 to 80 grams.

Pearly Parakeet

The Pearly Parakeet (Pyrrhura lepida) has the head dark blackish brown with mottled light on nape; ear-coverts creamy white; cheeks pale bluish green.

Upper mantle blue; robe bottom until uppertail-coverts, green. Scapulars green at the base, blue down; lesser wing coverts slightly green tinted olive; median coverts and older, mainly blue; some red at the leading edge of wing . Flight feather Blue above, secondaries with green in the outerweb; dark gray below. Underwing-coverts bright red. Sides of the neck, the throat and the top breast, mainly brown with some blue marks and points yellowish brown, which gives an overall scaled aspect; The underparts remaining are green with blue on the flanks and the thighs. Upper, the tail mainly brown, green in the basal area and narrow blue tips. Bill black-brown; bare periophthalmic grey; iris dark brown; legs black slate.

The plumages of both sexes are, apparently, similar.

taxonomic history

Confusing taxonomic history: until recently known as Pyrrhura perlata, but that name is actually applied to the known way long as Pyrrhura rhodogaster, currently a synonym for the species Pyrrhura perlata; the current species therefore assumes his next oldest name, Pyrrhura lepida. Forms a pair of species with parapatric Pyrrhura perlata, with which it is sometimes considered conspecific; the recent molecular phylogeny indicated that the closest relatives of these two are the Pyrrhura frontalis and the Pyrrhura molinae.

Description 3 subspecies:
  • Pyrrhura lepida anerythra

    (Neumann, 1927) – Similar to the species nominal but with the breast, the belly and the cheeks green with occasional shades of blue.

  • Pyrrhura lepida coerulescens

    (Neumann, 1927) – Similar to the species nominal, but with the forehead and the crown brown, gray throat and upper chest, green on the upper cheeks; bluer in the lower chest

  • .

  • Pyrrhura lepida lepida

    (Wagler, 1832) – Nominal.

Habitat:

The Pearly Parakeet, usually, inhabits humid forests of mainland. The species has been observed in forest edges, clear areas and second growth.

They are seen in flocks of up to ten birds, particularly in places where food is plentiful.

Reproduction:

They nest hollow logs. The laying is of 3-4 eggs incubados during 23 days; breeding needs about 7 weeks for independence.

Food:

probably catkins, small fruits and flowers.

Distribution and status:

Tamaño de su área de distribución (reproductor/residente): 585.000 km2

The Cotorra Pulcra is endemic to Northeast Brazil, to the South of the Amazon. Observed around the basin Xingu and its tributaries, from the river Pracuí and the left bank of Tocantins River, and from Belém and the Río grass, in For, east to around Sao Luis in Maranhão, and from northern Maranhão to the East of Rosary, although apparently no longer in some coastal areas, where according to sources, They were formerly quite common.

Today are rare and extinct in many parts of their former range (for example, North of Maranhão) due to large-scale deforestation, although they are, apparently, tolerant habitat alterations.

The coerulescens subspecies It is near extinction due to the almost total loss of their habitat. The species is found in protected areas but its integrity is compromised by the illegal logging.

Distribution 3 subspecies:

Note:

Pyrrhura lepida is the new name of the taxon Pyrrhura perlata, whose name has been shown to be applied first to an immature bird of that species, Crimson-bellied Parakeet (Pyrrhura perlata).

Conservation:

• Current red list category of the UICN: Vulnerable.

• Population trend: Decreasing.

• Population size : 6700 individuals.

Justification of the red list category

From a model of future deforestation in the Amazon basin, While shows some tolerance degraded landscapes, It suspected that the population of this species decline rapidly over the next three generations and, therefore, It has risen to Vulnerable.

Justification of the population

The population It is preliminarily estimated to number at least 10.000 individuals, approximately equivalent to 6.700 mature individuals. This requires confirmation.

Justification of trend

It is suspected that this species has lost between 47 and the 64,5% of habitat suitable within their distribution during three generations (18 years) starting from a model of deforestation Amazon (Soares-Filho et to the ., 2006, Bird et to the ., 2011). However, because the species seems to have some degree of tolerance to habitat degradation (A. Lees in litt ., 2011), It suspected to decline by 30-49% during three generations.

Threats

Despite an apparent tolerance of some degradation of the habitat, It is perhaps close to extinction in coastal areas of northern Maranhão, due to the large scale deforestation (Juniper and Parr, 1998). They are distributed within protected areas, but its integrity is compromised by the illegal logging (Juniper and Parr 1998). It is expected that deforestation in the Amazon basin to increase as land is cleared for cattle ranching and soybean production, provided by the expansion of the road network (Soares-Filho et to the. , 2006). The proposed changes to Brazilian Forest Code reduce the percentage of land to a private owner is legally obliged to keep as forest and include an amnesty for owners who deforested before July 2008 (That later they would be absolved of the need to reforest the land illegally cleared) (Bird et to the., 2011).

In captivity:

Rare in captivity.

It is a bird Vulnerable nationally in Brazil and protected by CITES Appendix II; each captive specimen of this species that is capable of reproducing, It is placed in a well-run program of captive breeding and not be sold as a pet, in order to ensure its long-term survival.
