“…Although the species is classified as Least Concern (IUCN 2012), with the exception of its breeding period, the rest of its annual life cycle remained poorly studied until recently. Since 2008 the migratory journey undertaken by individuals from Italy, Spain and Greece (Gschweng et al 2008, López-López et al 2009, López-López et al 2010, Kassara et al 2012, Limiñana et al 2012) was revealed with the aid of satellite telemetry. This new technology has also enabled scientists to investigate the species’s wintering habits on a quasi-daily basis for the first time (Gschweng et al 2012, Kassara et al 2012, Mellone et al 2012), a task that would have been almost impossible with traditional field surveys (but see Zefania 2001).…”

SummaryEleonora’s Falcon is a long-distance migrant of the Palearctic region. In recent years, the advent of satellite telemetry has enabled a more detailed investigation of the species’s migratory and wintering periods. In this study, we model the distribution pattern of four Eleonora’s Falcons originating from Greece within their wintering grounds in Madagascar with the use of satellite telemetry data and a niche-based technique, Maxent. The model predicted few highly suitable areas for the occurrence of the species, restricted to elevated areas receiving large amounts of precipitation during the wintering period, containing patches of primary and degraded humid submontane forests as well as cultivation. Most of these areas occurred within the previously estimated home ranges of the four falcons, as well as of three falcons from another independent study. Taking into account the ongoing alterations in landscape structure that occur within the eastern rainforest region of Madagascar, we believe that it is imperative to better understand the ecological requirements of Eleonora’s Falcon. To this end, we recommend the application of Maxent in the study of habitat selection of the species that could be further refined with the inclusion of biotic interactions and seasonal resource availability.
