Mises à jours terminées [5h10 du matin...]
Salut,
Ben on attend avec impatience les articles, on compte sur toi.
@+ momo :pangel1:
pour ma part je trouve cela intéressant , instructif :wink:
:lol: ca va m'occcuper pour un tit bout de temps ,apres jmatak aux eclectus :-D
Salut,
Juste une petite remarque pour dire que, parmi les articles prévus sur lesz perroks disparus, certaines espèces, même si elles sont extrêmement rares ne sont pas éteintes et pourront peut-être être sauvées
J'ai noté l'amazone versicolore, l'amazona guildingii , la psittacula echo, l'ognorhynchus icterotis, le bolborhynchus ferrugineifrons.
Pour ces espèces au moins, si tu fais une recherche google en international, tu trouveras des sites présentant des oiseaux vivants.
Cordialement
Séb
ouioui mais eteints dans la nature
certains aussi sont disparus ,peut etre survivant encore isolément,comme pour l'ara violet :(
avez vous la liste exacte des perroquets eteints eteints ?
en effet ,l'amazone de st vincent compte 500 oiseaux ,et les autres quelques dizaines .
je l'enleve donc de la liste
voila j'ai la liste:
Raiatea Parakeet (Cyanoramphus ulietanus) EX
Jamaican Green-and-yellow Macaw (Ara erythrocephala) EX
Jamaican Red Macaw (Ara gossei) EX
Lesser Antillean Macaw (Ara guadeloupensis) EX

Newton's Parakeet (Psittacula exsul) EX
Cuban Macaw (Ara tricolor) EX
Carolina Parakeet (Conuropsis carolinensis ) EX
et ceux disparus et ceux retenus qu'en cativité ? :|
le probleme est que ujne variete pour pouvoir survivre et ce regenerer doit comporté un minimum d'individu, c'est une des regles fondamentale de l'ecologie ainsi ces oiseaux meme si ils exixtent encore sont deja voué a l'extinction
cette regle bien que cruelle limite les problemes de derive genetique du a une trop grde consanguinité
cette limite appelé seuil limite de p^pulation c'est deja exprimé en france avec l'echec cuisant de la reintroduction de l'ours ds les pyrennées ( ou les personnes qui ont fait ça n'avait pas du suivre beaucoup de cour d'ecologie)
ainsi ces oiseaux pourront survivre longtemps en captivité mais ne seront jamais reintroduit ds le milieu naturel
c'est triste mais c'est comme ça et c'est trop tard.....
domage, j'aurai bien aimé voir un couple de spix en liberté....
Triste finalement, aucun espoir
non pour certaines c'est deja trop tard

Who's a pretty rare Polly? A report in The Mail on Sunday published on 29th March 1992
This extraordinary photograph is set to knock the parrot world off its perch.
Experts believe it shows a South American Glaucous Macaw, a breed which has not been seen for more than 100 years.
They claim it may be the only survivor. Conservationists were convinced that the magnificent bird had been driven to
extinction by collectors entranced by its beautiful plumage.
A British parrot breeder says he has accidentally uncovered the Glaucous Macaw after a mix-up over its identification
25 years ago. Harry Sissen spotted the mistake last month after importing what he thought was a pair of rare Lear's
macaws on loan from a zoo. When he inspected the birds at Customs he realised that the female was the "extinct"
Glaucous Macaw.
His amazing discovery will stun the parrot world, which had added the Glaucous Macaw to the long list of creatures
wiped from the Earth. Although there have been rumours that a colony lives in the remote forests of Paraguay, no
evidence has ever emerged to confirm that they were still alive.
"I was shocked when I first saw the bird as I immediately realised that it was a Glaucous Macaw," said the 53 year-old
Yorkshire farmer. "it must have been wrongly identified by the zoo in Europe. This bird fits the descriptions of the
Glaucous given by experts at the beginning of the century."
Mr Sissen, one of Europe's most successful breeders of rare parrots, is convinced that the bird is back from oblivion.
"What clinches it for me is the size of the bird. Records say that the Glaucous Macaw is smaller than its near relative,
the Lear's. And when you compare the two birds you can see that the Glaucous's breast feathers are sea blue rather
than bright blue, its beak has a pale strip and the skin around the eyes and beak is a paler yellow."
News of the discovery is bound to spark a furious debate over the bird's identification. Mr Sissen's claims are backed by
two leading parrot breeders, who have studied the eight Glaucous Macaw skins in museums around the world.
Joe Cuddy and Robin Pickering, both 33, have examined the bird and are adamant that it is a significant find. I have no
doubt that it is a Glaucous," said Mr Pickering.
But the zoological department of the Natural History Museum in Tring, Hertfordshire, which has the remains of two
Glaucous Macaws, was undecided when asked by The Mail on Sunday to identify the bird from photographs. "The head is
reminiscent of Glaucous, but according to our description the feathers around the lower face should be a sooty colour,"
said scientific officer Peter Colston. "It is not clear-cut. I would like to see the live bird."
The bird, worth at least £ 50,000 on the black market, is being kept at a secret quarantine station before it is released next
week. It was imported from Mulhouse Zoo, near Strasbourg, France.
But for Mr Sissen, who has several of the world's rarest parrots in his collection of 450 birds, the Glaucous Macaw is priceless.
"It is like asking someone how much they would pay for a dodo," he said. "The birds are on loan for breeding over the next
three years, maybe they will produce some youngsters."
But now the search begins for a male Glaucous Macaw. There is a slim chance that there may be another in a private collection
that has been misidentified.
Mr Sissen said his Glaucous Macaw could not be returned to the wild as it has spent 25 years in captivity and the flight feathers
have not grown, which would prevent it escaping from predators.

Mais je pense que vous connaissez tous cette vieille histoire...
