<p dir="ltr">The Brazilian biologist Neiva Guedes, who managed to stop the blue macaw from being in danger of extinction, said that in order to face the advance of the destruction of the habitat that hinders its reproduction, she created artificial nests to promote its multiplication and study its behaviors, then thirty years of work in the great Mato Grosso do Sul wetland, it was reported this Wednesday. &nbsp; <p dir="ltr">Invited to the fourth meeting of Behavioral Biology of the Southern Cone, which took place at the Faculty of Exact and Natural Sciences of the University of Buenos Aires, and after giving a lecture, biologist Neiva Guedes, who is president and founder of the Institute Arara Azul, told the information service on Science, technology NEXciencia about the process by which the Anodorhynchus hyacinthinus (blue macaw) went from the category of &quot;endangered&quot; to &quot;vulnerable&quot; on the Red List of Threatened Species of the International Union for Conservation of Nature (IUCN). &nbsp; <p dir="ltr">&quot;I have no doubt that the change in category was achieved thanks to our work with the nests and the alliances with farmers and laborers, because I alone with my team could not have done much,&quot; said the biologist who added that &quot;awareness is Central, and that was achieved in the Pantanal because the people protect the azuis macaws, the red macaws, the toucans, they understand the importance of conserving biodiversity in their territory&quot;. <p dir="ltr">How artificial nests are used <p dir="ltr">Less durable than the natural ones, the artificial nests are wooden boxes with an opening, which can be active for up to 30 years and, together with a metal ring that is fixed to the trunk, discourage the irruption of monkeys and other arboreal species, potential predators of the macaw. . &nbsp; <p dir="ltr">In turn, the specialist said that deteriorated natural nests are also recovered and that the bird uses them again, and it is through this action that &quot;valuable information was obtained about their behavior as a couple and with the young.&quot; &nbsp; <p dir="ltr">&quot;In terms of behavioral studies, the differential that they contribute is enormous. We can observe hundreds of nests, we see the most intimate mechanisms of egg incubation and chick feeding, the detail of the conflicts that occur with other species , mammals included, that dispute their nests for shelter or also for reproduction, and the link with the predators that stalk them. We see that the behavior patterns are the same, whether they are natural or artificial nests,&quot; he explained. &nbsp; <p dir="ltr">The advance of the clearing and the agricultural frontier are part of the human action that affects the reproduction of this bird, for which the Guedes team and the nearby inhabitants have already placed at least 700 nests. &nbsp; <p dir="ltr">The result was an increase in blue macaws. They went from 1,500, when Neiva began his research and conservation work, to 5,000 in Mato Grosso alone, out of a total of 6,500, if those living in the Par&aacute;, Maranh&atilde;o and Tocantins regions are included.
