Look, the situation is that the bigger the gene pool the better. If for example we bring in 400 pairs of Moluccan Cockatoos and over 5 years (it takes on average about 4-5 years to get a wild caught pair to breed) only 50 pairs produce chicks, then we obviously end up with a gene pool only consisting of those 50 pairs. The way things are working now those other 350 pairs may never breed. The reasons for why there is not a good rate are many, and not entirely understood. (More field research is needed, but there is no time..) But if for example every 2 years another 100 pairs were brought in and checked for health (better than what is currently done), NOT medicated out the wazoo, and in general treated better (perhaps 1 or two pairs per crate instead of the 50-100 birds per crate now (which is only one reason why I am against continued imports of birds). I believe that this would bring up the production rate, and would in the long run relieve the threat that some of these species are under. As an aside, to successfully breed, you need to be feeding the absolute best diet that science knows about for parrots. So sickly chicks have little to do with food. Parrots will not breed in close quarters, they need room. So their situation has little to do with sickly chicks. Those factors have to do with sickly pairs, and good breeders do what is needed in order to insure that their birds are not only healthy, but have what they need to produce. After all most of these breeders have several thousands of dollars invested, not only in the birds themselves, but also in their facilities. The plan that I would like to see and am going to work for is basically: 1. Stop imports for the pet trade. Period. 2. Allow imports of birds for "certified" breeding centers, not just Zoo's. Zoo's have their place but they are mainly for people to go see animals at. Breeding Parrots just don't really work when people are streaming by (like at the National Zoo in DC where they have been trying to breed endangered Black Palms for the last several years in a small cage with people snapping flash pictures at them). It just doesn't work. 3. Lobby all countries who now allow no exports of Parrots to open up slightly for exporting birds to breeding centers around the world. Perhaps with some sort of pay back by getting young birds to release into the wild. Obviously this all takes money to manage. That's why you would also need some way of generating income from the birds brought into the country. Breeders for the most part would be more than willing to pay extra for pairs if they knew that they had been WELL taken care of on the way into the country. Money can be generate from this and from the sales of domestic breed baby birds. This solution is not complete, but it is better than just cutting off the imports of birds that will either die off entirely or be smuggled in anyway. The buying public is just not aware of what is going on either. > let's get some input from geneticists about how best to do this > before we jump on that bandwagon: how many new birds are needed > to achieve the desired effect? what is the desired effect? how do > we best breed the birds? etc?

The goal as I see it is both. We need to have healthy domestic pets to deal with the demand that is being put on the wild populations, but we also need to provide essentially a Noah's Ark service for those species going out of existence. Hamsters breed far to readily and far to often to be equated with Parrots. The youngest most parrots breed is at about 5 years of age, with most older than that. If you start running averages, and numbers out into the future you see that within about 10 years not only will the wild population be gone for the most part, but the growth of the domestic population will fall off. New pairs setup today will not produce (on average) until five years from now. There is not enough production of domestic birds today to fullfil demand and to save birds back for future production and preservation. One example that I know is the Rose Breasted Cockatoo from Austrailia. This bird is not endangered, however it does illustrate some of the problems that I am talking about. This bird breeds fairly readily, ask anyone from Austrailia, but even so, here in the US, where new birds have not been brought into the country since (I think) 1960, there still are not very many breeding pairs. After Austrailia cut off exports we were left with whatever was in the coutry at the time. The prices (which is a good indication of how many are available) for these birds has remained high $3,500+. They are just now starting to get well established in breeding populations in the US. Had we been able to get a few pairs every so often I think that there would be a larger and more viable population of these birds in the US. There are other species of Austrailian birds that have died off in the US becuase of several factors, original population size being amoung them. Anyway I could go on about this for a while, the end picture is that to totally cut off imports is sticking our heads in the sand and hoping that the problem will go away. It won't. The Moluccan Cockatoo is under the dual pressures of habitat destruction and wide spread desease, in addition to capture for the pet trade. Unfortunatly for these birds (or fortunatly) part of their continued survival as a species rests in the hands of breeders around the world. I don't believe that we can stop ourselves from cutting down every tree in the world hence the rainforests will be gone within the next 10 years. With those gone the habitat of these birds is also gone. Do we help them survive, in the hope that we will wake up and start setting aside land as preserves, or do we just ignore the problem and go our own way. We aren't stopping the import of rainforest hardwood, oil taken from jungles, paper created with rainforest wood, etc... Yet something that we can help survive, we want to ignore. I feel that banning the importation of birds for the pet trade is a good idea. I don't feel that the ban should be total. Kurt Baumann 703.709.9890 InterCon Systems Corp.
