Article
Understanding the levels and drivers of contamination in top predators is important for their conservation and eventual use as sentinels in environmental monitoring. Therefore, metals and trace elements were analyzed in feathers of Bonelli’s eagles (Aquila fasciata) from southern Portugal in 2007-2013, where they are believed to be exposed to a wid...

Ospreys bred along most of coastal Portugal until the beginning of the 20th century. Thereafter, a continuous decline due to persistent persecution and habitat loss led the species to extinction as a breeder in 2002, long after its disappearance from the rest of continental Iberia. Reintroduction by hacking was the only remaining option to restore...

Species ranges often change in relation to multiple environmental and demographic factors. Innovative behaviours may affect these changes by facilitating the use of novel habitats, though this idea has been little explored. Here we investigate the importance of behaviour during range change, using a 25-year population expansion of Bonelli’s eagle i...

Within the framework of the Osprey (Pandion haliaetus) reintroduction in Portugal, which began in 2011 in the Alqueva reservoir and aims at establishing a founder breeding population in the area, 12 nestlings were translocated in 2015, 6 from Sweden and 6 from Finland. These young finished their development in the hacking tower at the shore of the...

Tree-nesting is an uncommon breeding behaviour in European populations of Bonelli’s eagle (Aquila fasciata). As little is known about its nest site selection in forest habitats, we studied 52 trees used for nesting by 32 breeding pairs from the fast growing tree-nesting population of Southwest Portugal. Generalized Linear Mixed Models and General L...

Breeding Ospreys (Pandion haliaetus) were common in Portugal at the beginning of the 20th century. Thereafter, a continuous decline led them to as few as 3 pairs in 1978 when the species was rediscovered in the Southwest coast. Against all odds, this relict population managed to survive for 25 more years until the last individual disappeared after...

Project
The Osprey Reintroduction Project aims at the reestablishment of the species as a breeder in the wild in Portugal. It was an initiative of CIBIO – Research Centre in Biodiversity and Genetic Resources with the financial support of EDP Energias de Portugal and the institutional collaboration of the Casa de Bragança Foundation, which owns the estate where the project facilities are located, and of EDIA (company that manages the reservoir) and ICNF (Nature Conservation and Forests Institute). The ultimate goal of the project is contributing to the recovery of a breeding Osprey population in its historical range along the Portuguese coast, from where the species disappeared as a breeder at the beginning of the present century. The project is part of the international efforts to recover the osprey in southern Europe, where its populations are currently small and endangered. The project is to be developed stepwise, and the goal of the present stage is the establishment of a founder breeding nucleus in an area of suitable ecological conditions – the Alqueva reservoir. For that, 10-12 young per year were translocated from Finland and Sweden to a hacking tower located at the Monte do Roncanito, Roncão estate, beside the Alqueva reservoir. The project is implemented in the strict agreement with the pertinent national, international, and donor countries’ legislations.
