    Home range requirements in Bonelli’s eagle (Aquila fasciata): prey abundance or trophic stability?
    (European Journal of Wildlife Research, 2019) Martínez Miranzo, Beatriz; Banda Rueda, Eva Isabel; Aguirre de Miguel, José Ignacio
    Prey abundance is one of the limiting factors for establishment a home range. In particular, biomass abundance could act as a key element for generalist top predators, with wide prey type spectrum, for establishing their home ranges. We studied if biomass abundance may act as a limiting factor for the establishment of home range in a generalist top predator, Bonelli’s eagle (Aquila fasciata). We used GPS satellite data on breeding individuals over a 10-year period to deepen into home range behaviour. To quantify biomass abundance, we performed surveys at different periods of the year cycle for potential prey inside the home ranges and outside them. We checked if differences in biomass were identified between home ranges and potential adjacent areas. Also, annual and seasonal variation in biomass abundance may be recorded. Variations in biomass abundance among home range were detected but no annual or seasonal variation within home range was identified. Differences in biomass abundance were identified between each of the home range and their potential adjacent areas. Although biomass abundance is lower inside the home range, it remains stable throughout the year while strong fluctuations in biomass abundance were detected outside them. Our results show that Bonelli’s eagle may establish their home range based on permanent biomass stability (Trophic Stability Hypothesis) rather than great seasonal but unpredictable abundances. This approach may have strong implications for management conservation programs of territorial top generalist predators.

    Differential spatial use and spatial fidelity by breeders in Bonelli’s Eagle (Aquila fasciata)
    (Journal of Ornithology, 2016) Martínez Miranzo, Beatriz; Banda Rueda, Eva Isabel; Gardiazabal, Andrea; Ferreiro Alcántara, Ernesto; Aguirre de Miguel, José Ignacio
    In recent years, long-term studies based on movement monitoring tools have improved our knowledge about spatial ecology and home range behaviour of endangered species. In order to study individual spatial–temporal variations in size, use and fidelity of home ranges and other spatial parameters (kernel at different levels), and determine the influence of sex and different annual periods in these variations, 17 adult breeders (of both sexes) of an endangered territorial raptor, Bonelli’s Eagle (Aquila fasciata), were equipped with GPS satellite transmitters and tracked over a 7-year period in Aragón (northeast Spain). The home range (kernel 95 %) of these eagles showed high individual variations as well as other spatial parameters (kernels 75, 50 and 5 %). No interannual variations for the same individual were found. Females changed home range size and use during the year, it being different in the breeding season. Home range fidelity was high for all individuals (overlap 76.18 %) over the three annual periods in all years. Nevertheless, fidelity to nesting areas was low (only 30 %) during the same periods. This work highlights the importance of long-term monitoring studies to elicit information on home range behaviour for developing accurate conservation guidelines. Maintenance of home range size and fidelity across years assures that the adoption of any conservation management plan would have a lasting impact over time. In addition, protection zones should be increased to critical areas (kernel 75 %) and restriction of specific activities causing disturbance during the breeding season should be implemented.
