The Black Vulture pairs usually initiate copulations in January and continue with the copulatory behaviour even after laying as encouragement as well as reinforcement of the bonds, and perhaps as a result of the excitement produced by the onset of incubation.
The post-laying copulations are quite frequent in the first weeks. They take place in the nest during the relief and gradually decrease in frequency, and may last for more or less time. These matings do not occur in isolation, but usually are accompanied by a wide array of caresses and offerings, like sticks, grass or other material to tidy up the nest.
But what is unusual is to observe this behaviour in the month of June, along with a chick 63 days old weighing of about 6kg.
This is what we saw last Thursday 6th in the nest of Neus and Oriol, who from the beginning showed their willingness to breed this season, as their late union, in the third week of February, did not stop them from beginning the breeding process.
In this case, despite the efforts of Oriol, copulation was not consummated, but it is certainly a sign that the couple continues to intensely strengthen its ties.
The reintroduction project of the Black Vulture in the Pyrenees is promoted by the Departament d’Agricultura, Ramaderia, Pesca, Alimentació i Medi Natural de la Generalitat de Catalunya and by the Fundació Catalunya – La Pedrera. GREFA and Trenca are involved in the assisment and implementation of the Project, toghether with the Alinyà Natural Site staff and the rangers of the NHR of Boumort. The Estació Biològica del Pallars Jussà carries out several educational actions related to the project. REE is markedly engaged in financing the transmitters that allow us to radio track the black vultures from the project.
