Glaucous Macaw

Description:

72 cm.. length.

Glaucous Macaw

The plumage general of the Glaucous Macaw (Anodorhynchus glaucus) It is light blue, almost turquoise top, with strong grayish hue in head and underparts.

Uppertail Blue-Green; undertail gray.

The bill It is dark blackish gray, the naked flames in the base lower mandible they are yellow, but paler than the periophthalmic skin; the irises is dark brown, the periophthalmic skin Nude yellow; the legs They are dark.

Habitat:

probably he occupied Gallery subtropical forests with cliffs, but also used lightly wooded savannas and rich in palm trees. The few contemporary records suggest it was naturalists gregarious.

Reproduction:

It has been reported that anidaba on steep slopes or cliffs, or less generally in the cavities of trees and the average size of laying It was probably two eggs

Food:

Its diet It was probably basic nuts palm Butia horizontal (nearest equivalent in rank to size nuts Syagrus used by the Indigo Macaw, It is having the same dimensions peak).

Distribution:

Extensión de su área de distribución (cría/residente): 1 km2

the Glaucous Macaw They were distributed at the time by the south-eastern South America, where apparently they were recorded in average growth of major rivers, including Parana River, the Uruguay river and the Río Paraguay, with most of the evidence of a prior distribution in the province of Currents, to the North of Argentina; cases were also recorded in western Uruguay and Southeast of Brazil (Rio Grande do Sul and Paraná), and evidently in the south and east of Paraguay. The records of Bolivia They seem wrong. It is almost certainly extinct after a precipitous drop in the early nineteenth century. Only two records in the twentieth century.

Conservation:

• Current red list category of the UICN: In Critically Endangered.

• Population trend: Unknown.

• Population size : 1-49 individuals.

Justification of the red list category

This species was recorded in the last decade 1960 and it is likely that its population has declined dramatically as a result of hunt, Besides the degradation and habitat destruction. However, you may still exist, since not all its wide range of data, above wide, It has been adequately studied, and there have been persistent and convincing local reports. Any remaining population is likely to be small, and for these reasons it is treated as in Critically Endangered.

Justification of the population

It is assumed that any remaining population is small (counting less than 50 individuals) due to lack of confirmed records since the early 1960.

Threats

The settlement of the major river basins within its range was allegedly accompanied by the widespread loss of palms, whether by direct cleaning for agriculture or suppression of regeneration by livestock settlers. The palma de Horizontal, of the species probably fed, It was chosen to be cleared by early settlers because it was an indicator of good soil quality (Necklace et to the. 2014). Widespread loss of gallery forests could also have had an impact on the species (Necklace et to the. 2014). The size and appearance of the bird probably made him a prime target for hunters, and even capture pups as pets It could have been important. There is some evidence that were sold, but few to support various claims that there have been recent trade of live specimens.

Any current trade in eggs, skins and live specimens would obviously be extremely damaging.

Conservation actions underway

    Appendix I of CITES and protected by Brazilian law.

    – There have been several attempts (so far unsuccessful) to rediscover the species.

    – There are proposals for funding under way to try to fund a work program to confirm the presence of this species in the wild.

Conservation Actions Proposed

    – Conducting interviews with the local population, especially with parrots and ancient hunters assets, to assess the likelihood of any population remains.

    – Getting ready to follow up any positive data from these interviews.

In captivity:

There is some evidence that were sold, but few to support various claims that there have been recent trade of live specimens.
