- Abstract
Investigates possible causes of territory desertion among Bonelli's eagles Hieraaetus fasciatus in Murcia (southeastern Spain): low demographic parameters, low habitat quality and competition with Golden eagles Aquila chrysaetos. Surveying of a Bonelli's eagle population; Comparison of abandoned and occupied territories to find differences in demographic parameters (flight rate, productivity and mortality) or habitat characteristics; Mortality that was significantly higher in abandoned territories; Abandoned territories that also had larger areas of forest and extensive agriculture, while occupied territories had more shrublands; Competition with Golden eagles that was not a determinant of territorial abandonment but interacted with human persecution of the species; Management implications that are discussed.
