They also repaired two other nests in the area that needed maintenance in order to be used by the species again. What led to the collapse of the now-rebuilt nests was the breakage of tree branches that previously supported them, as well as bad weather. The technicians had to build an artificial structure reinforced with metal bars to recreate the natural nesting structures. In all these nests, technicians also placed plant material (small branches, sticks, etc.) to mimic natural conditions and make these structures attractive to the species again. To install these five nests, they had to carefully climb to the top of large pine trees, usually selected by Cinereous Vultures to nest in the region. The intervention lasted three days.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"http:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/The-appearance-of-the-tree-before-top-left-and-after-top-and-bottom-right-the-nest-reconstruction-\u00a9-LPN-1024x768.png\" alt=\"The appearance of the tree before (top left) and after (top and bottom right) the nest reconstruction \u00a9 LPN\" class=\"wp-image-26750\" srcset=\"https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/The-appearance-of-the-tree-before-top-left-and-after-top-and-bottom-right-the-nest-reconstruction-\u00a9-LPN-1024x768.png 1024w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/The-appearance-of-the-tree-before-top-left-and-after-top-and-bottom-right-the-nest-reconstruction-\u00a9-LPN-300x225.png 300w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/The-appearance-of-the-tree-before-top-left-and-after-top-and-bottom-right-the-nest-reconstruction-\u00a9-LPN-768x576.png 768w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/The-appearance-of-the-tree-before-top-left-and-after-top-and-bottom-right-the-nest-reconstruction-\u00a9-LPN-16x12.png 16w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/The-appearance-of-the-tree-before-top-left-and-after-top-and-bottom-right-the-nest-reconstruction-\u00a9-LPN.png 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><em>The appearance of the tree before (top left) and after (top and bottom right) the nest reconstruction \u00a9 LPN<\/em><\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Promising results already produced<\/strong><\/h4>\n\n\n\n<p>The effort now made at Herdade da Contenda has already started to produce results! Only three days after its reconstruction, it was already possible to observe a pair of Cinereous Vultures perched on one of these nests. A strong nest structure is crucial since when that same nest collapsed at the end of last spring, the small chick at the nest fell and died. Now, Cinereous Vulture pairs will be able to breed there again, enjoying a reinforced nesting structure, which will hopefully help increase the chances of successful reproduction this time.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Herdade da Contenda is a very important place for the species as it is home to the second largest Cinereous Vulture breeding nucleus in Portugal, with ten breeding pairs. However, in 2022, only three pairs successfully reproduced (raising, as usual in the species, one chick each), partly due to the collapse of natural nests during the breeding season.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1021\" height=\"1024\" src=\"http:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN-1021x1024.png\" alt=\"Cinereous Vultures in the newly rebuilt nest (image taken from a distance, through a telescope) \u00a9 LPN\" class=\"wp-image-26746\" srcset=\"https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN-1021x1024.png 1021w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN-300x300.png 300w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN-150x150.png 150w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN-768x770.png 768w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN-12x12.png 12w, https:\/\/4vultures.org\/wp-content\/uploads\/2023\/01\/Cinereous-Vultures-in-the-newly-rebuilt-nest-image-taken-from-a-distance-through-a-telescope-\u00a9-LPN.png 1280w\" sizes=\"(max-width: 1021px) 100vw, 1021px\" \/><figcaption class=\"wp-element-caption\"><em>Cinereous Vultures in the newly rebuilt nest (image taken from a distance, through a telescope) \u00a9 LPN<\/em><\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Monitoring the breeding season<\/strong><\/h4>\n\n\n\n<p>With the Cinereous Vulture breeding season starting, the partners will begin monitoring the nesting of the species in the coming weeks in Herdade da Contenda and other regions of intervention of the LIFE Aegypius Return project along the Portuguese and Spanish border.

As a scavenger, it plays a vital role in nature by feeding on carcasses, helping keep ecosystems functioning and potentially minimising the spread of diseases.&nbsp;<\/p>\n\n\n\n<p>Individuals take quite a long time to reach sexual maturity (4 to 5 years), and each breeding female lays only one egg per year. The reproductive process is also quite lengthy: from the construction or arrangement of the nest to the independence of the chicks, it takes about nine<strong>&nbsp;<\/strong>months. Cinereous Vultures provide excellent parental care for their offspring, and the pair shares various responsibilities, such as incubation, nest guarding and provision of food.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>O projeto LIFE Aegypius Return&nbsp;<\/strong><\/h4>\n\n\n\n<p>The LIFE Aegypius Return project aims to consolidate and accelerate the return of the Cinereous Vulture in Portugal and western Spain by improving its habitat and foraging conditions, minimising threats and developing national capacities.\u200b The project team will implement targeted conservation actions across ten Natura 2000 sites, along almost the entire Spanish-Portuguese border, to double the Cinereous Vulture breeding population in Portugal to at least 80 pairs in 5 colonies and downgrade the national status of the species from Critically Endangered to Endangered by 2027.<\/p>\n\n\n\n<p>O projeto LIFE Aegypius Return \u00e9 cofinanciado pelo Programa LIFE da UE <a href=\"https:\/\/cinea.ec.europa.eu\/programmes\/life_en\" target=\"_blank\" rel=\"noreferrer noopener\">Programa LIFE<\/a> e tem um or\u00e7amento de 3,7 milh\u00f5es de euros.
