Hi Arara Preta,
Thanks for sharing your very informed views on the Ararajubas and some other species. I have found a lot of valuable information in your writings. In fact, this thread has contained some of the most up-to-date information on Ararajuba conservation AND aviculture that I have seen anywhere over the last few years. There was a lot of information disseminated when the WPT’s Golden Conure fund was first started, and then there were regular updates for a while, but after that I have not heard anything much new for the last couple of years. Thank you for the timely update to remind us that all is not going so well with the Golden Conure’s conservation efforts.
It is reassuring to hear that some of the displaced Ararajubas have adapted well to nest in dead trees found on cattle grazing land. However, one wonders if their very special and possibly unique family group nesting behaviors will become diminished or even be lost forever as these behaviors become less appropriate in their new environments, where these behaviors may begin to lose their evolutionary value. Do you know if the Ararajubas which are nesting in dead trees found on cattle grazing land are nesting there as pairs or are they still nesting in family groups?
But, of course, as you have already mentioned, even these new nesting sites on cattle grazing land are, at best, only a very precarious solution.
I also have a query about comparing the creation of the ox bow lake, with the creation of the Tucurui Dam. I have not been to that area, so I do not know the area and I do not know what the dam is like, but I wonder why the filling in of the Tucurui Dam did not leave a lot of dead hardwood trees which the Ararajubas could have used as nesting sites, just like the dead hardwood trees formed in the ox bow lakes?
Would you mind telling me whether you are still currently actively involved in the fieldwork for the conservation of the Ararajubas? I ask because I would like to know where Ararajuba conservative efforts are heading. Are appropriately clustered groups of artificial nests being set up for them in the appropriate habitats, as seems to be the immediate emergency solution here? How are the difficulties in eastern Paragominas being handled? Or have we given up on conservation efforts in that region?
Thanks again for your very informative posts,
