The two young eagles are joined born in the Parc del Garraf
The two young eagles that were born in April at the Garraf Park have been ringed by members of the Biology Conservation Team of the Faculty of Biology and the Biodiversity Research Institute of the University of Barcelona (IRBio). The ringing tasks took place on May 16th within the framework of the long-term scientific monitoring project promoted by UB-IRBio experts with the collaboration of the Mountain Support Group (GMS) of the Rural Agents Corps of the Generalitat de Catalunya and the staff of the Network of Natural Parks of the Diputació de Barcelona. This research and conservation of biodiversity project has as its main objective to know the state of the population of Bonelli's Eagle, the most significant vital rates (productivity, survival, etc.) and the population dynamics of the species.
Ring and study the chicks in their natural habitat
Bird ringing is a scientific practice that is used around the world to improve the knowledge of the biology and the conservation of the birds. This methodology is decisive for knowing, for example, life expectancy or periods and areas of migration, among other aspects that are essential for improving the conservation of species.
During the ringing tasks, UB-IRBio experts were able to verify that the two chicks show a good state of health and develop normally. Specifically, in the bird a ring was placed in each pot: a conventional one to record each eagle and one with a code to identify the copies at a distance. Each ring has the source address of the bird, so that anyone who finds a ringed bird can report the finding data.
Both ringed chicks will coexist for a few months with their ancestors and will learn the art of hunting and other abilities to survive in the natural environment. When the summer is over, young eagles will leave the birthplace and for two or three years they will take on an independent life, during the period of dispersal, until they end up settling in their own territory and matching
The Bonelli's Eagle: a species endangered throughout Europe
Bonelli's or Bonelli's Aqua (Aquila fasciata) is a medium-sized day raptor typical of semi-arid and warm regions of Europe, Asia and North Africa. This species lives in the Mediterranean mountain ranges and nests preferably in cliffs, although it can also be done in trees. Hunting in open fields (garrigues, areas of lax vegetation, small crops, etc.) and their favorite prey are rabbits, partridges, tudons and other birds. Adult eagles live as a couple and occupy the same territory throughout the year. During the breeding season, they make nests with branches in holes or outflows of the cliffs that can measure two meters in length and one meter in height.
In Catalonia, the population of Bonelli's eagle suffered a notable decline from the 1970s until 2000, when they reached the lowest known number of 66 breeding pairs. Since then, the population has recovered slowly and nowadays it already has about 80 couples. This species, also known as Bonelli's eagle, in tribute to the ornithologist Franco Andrea Bonelli - who first documented it in 1819 - is considered a species in danger and is protected in the autonomous, state and European sphere.
From the threat to conservation: a common goal
The Conservation Biology Team, led by Professor Joan Real, from the Department of Evolutionary Biology, Ecology and Environmental Sciences and the Biodiversity Research Institute of the University of Barcelona (IRBio), is a scientific reference since 1980 in the search for the ecology of Bonelli's eagle - and in the contribution of solutions to improve their conservation.
Protecting and conserving this emblematic species in Mediterranean ecosystems is a responsibility of all, and that is why the University of Barcelona and the Diputació de Barcelona join forces to improve the protection of the different populations in Catalonia.
