FAUNA EM EXTINÇÃO - ARARAS BRASILEIRAS
Arara-azul - Blue macaw (Anodorhynchus leari)
That species occurs in a region near little blue macaw's habitat. Although it can be found also in "caatingas" in the northern Bahia, that species occupies a different kind of "caatinga".
There are today approximately 60 macaws of that species, but until the 70's we did not know practically anything about them. Discovered by science in the last century, that genus of macaws has appeared from time to time in the live birds market in this century, but its origin is unknown.
It has never been a frequent product in that market and therefore we can only suppose that it was hunted by man as a source of food since there are no records about that activity as far as this kind of macaw is concerned.
Arara-azul - Blue macaw (Anodorhynchus glaucus)
Extinct, probably in the end of the last century, it was the first Brazilian bird to be ripped away from earth. Little is known about its wild life besides that it used to live on the rocky riverbanks of Paraná River where it probably nested, like the Anodorhynchus leari and other populations of Anodorhynchus hyacinthinus are used to do on northeastern steep cliffs.
Like the other two macaws of genus Anodorhynchus, it has a predominant blue color rather a dull grayish-blue different of the brilliant plumage of the Anodorhynchus hyacinthinus or of the body and tail of the Anodorhynchus leari.
Arara-azul - Blue macaw (Anodorhynchus hyacinthinus)
The largest of all macaws and the largest of all psittacidae family (which includes parrots, macaws, parakeets etc.) all over the world. It is the most widely distributed of the blue macaws. They occur along the Middle-West, part of Brazilian northeast, strips of southern Amazônia, and some go as far as the extreme northwestern Sao Paulo.
The blue macaw preservation is a very troublesome matter due to the pressure exerted on habitat by encroaching humans. Its former habitat has been extremely modified by deforestation, specially in the last 50 years. Losing environment means extinction of species in the places they occur. Simultaneously to that, there is the illegal trade of live birds carried out, not only within the country but also overseas, to where they are smuggled.
If there is no awakening of environmental consciousness both in Brazil and in foreign countries, the maintenance of this illegal market will result in the extinction, in few years, of the largest macaw living today on earth.
Arara-azul (Anodorhynchus leari)
Esta espécie habita uma região próxima à área de ocorrência da Ararinha-azul. Embora também viva na região de caatingas do norte baiano, esta espécie ocupa um tipo diferente de caatinga.
Existem, hoje, cerca de 60 araras desta espécie na natureza. Conhecemos lá alguns detalhes sobre a vida desta espé
cie, mas até a década de 70 não sabíamos praticamente nada. Descoberta para a ciência no século passado, esta arara esporadicamente apareceu no comércio de aves vivas ao longo deste século, sem que sua origem fosse conhecida.
Nunca foi freqüente no comércio de animais vivos e somente poderemos especular uma caça pelo homem como alimento, já que não existem registros desta atividade sobre a arara.
Arara-azul (Anodorhynchus glaucus)
Extinta provavelmente no final do século passado, foi a primeira ave brasileira a desaparecer da face da terra. Pouco é conhecido de sua vida em liberdade, sabendo-se unicamente que vivia nos paredões rochosos do Rio Paraná, onde provavelmente nidificava, como faz nas barrancas do nordeste a arara Anodorhynchus leari e algumas populações de Anodorhynchus hyacinthinus.
Como as outras duas araras do gênero Anodorhynchus, possuía a cor azul como dominante, embora fosse um azul-acinzentado fosco, sem o brilho da plumagem de Anodorhynchus hyacinthinus ou do corpo e cauda de Anodorhynchus leari.
Arara-azul (Anodorhynchus hyacinthinus)
A maior de todas as araras e de toda a família dos psitacídeos (a que engloba papagaios, araras, periquitos e assemelhados) no mundo. Dentre as araras azuis, é a que possui distribuição geográfica mais ampla, ocupando no passado todo o Centro- oeste e parte do nordeste brasileiro, além de penetrar em faixas do sul da Amazônia, chegando ao extremo noroeste do Estado de São Paulo.
A situação de conservação da Arara-azul é bastante problemática devido à pressão humana. Sua antiga área de ocorrência foi extremamente alterada por desmatamentos, especialmente nos últimos 50 anos. A perda do ambiente significa a extinção da espécie nos locais onde ocorre. Ao mesmo tempo, há o comércio ilegal de aves vivas tanto no País quanto no exterior para onde são contrabandeadas.
Caso não haja uma firme tomada de consciência tanto internamente quanto no exterior, a manutenção deste mercado ilegal levará à extinção a maior Arara da face da terra em poucos anos.
