“…The species is listed as ‘Endangered’ by IUCN with a global reproductive population estimated at less than 1,000 mature individuals and a decreasing trend (BirdLife International 2016). Although the main factors threatening the species are thought to be high non-natural mortality by human persecution (Sarasola and Maceda 2006, Sarasola et al 2010, Barbar et al 2016) and habitat loss (Bellocq et al 2002, Fandiño and Pautasso 2013), there is evidence that they suffer unquantified mortality by other human related factors such as electrocution in power lines (Chebez et al 2008). Here we quantified susceptibility to electrocution and electrocution rates for birds of prey in arid and semi-arid biomes of central Argentina where we have been studying Crowned Solitary Eagles since 1999.…”

SummaryHigh mortality by electrocution has been suggested to be the main factor behind the reduction of several birds of prey populations across the world. Almost nothing is known, however, about the impact of power lines on this group of birds in the Neotropical Region. Here we estimate electrocution rates for birds on power lines covering both arid and semiarid biomes of central Argentina. We conducted six bi-monthly power line and raptor surveys throughout 355 km of lines and roads covering an area of approximately 12,000 km2. We described the structural design of 3,118 surveyed electricity pylons. We found 34 electrocuted individuals of four bird families that constitute an annual bird electrocution rate of 0.011 bird/pylon/year. Bird electrocution occurred mostly on concrete pylons with jumpers above the cross-arm. Larger birds of prey had a higher electrocution rate than smaller species. The Crowned Solitary Eagle Buteogallus coronatus was disproportionately affected by this mortality source when compared with its low population density. Electrocution incidents occurred mostly in a few electric pylon designs that represent only 10.2 % of the power pylons monitored in the study area. Therefore, the change or modification of a small fraction of pylons would almost eliminate bird electrocution incidents in our study area. Our results prove that electrocution is a relevant cause of mortality for Crowned Solitary Eagles and urgent mitigating actions are needed to reduce this mortality factor.

“…There is, however, evidence of population retraction or at least of widespread persecution across the country for some species. This is the case of the Crowned solitary eagle ( Buteogallus coronatus ), the Andean condor ( Vultur gryphus ) and the Striated caracara ( Phalcoboenus australis ), for which persecution led to a decline or extinction of local populations [ 41 , 42 , 43 , 44 ].…”

“…), predation on poultry, the main driver of conflicts involving this species in Colombia and Ecuador [ 29 , 30 , 49 ], has been recorded in the only nest documented for the species in the country [ 55 ]. On the other hand, the Andean condor and the Crowned solitary eagle are directly persecuted in some regions of Argentina as they have been accused of preying on livestock [ 21 , 34 , 41 , 48 ]. Given that most local settlers of the Yungas are traditionally seasonal farmers and transhumant herders [ 56 ], there could be a potential human-raptor conflict.…”

Wildlife persecution due to human-wildlife conflict has become a serious concern for biodiversity conservation, especially for many endangered species. In this context, conservation approaches need to consider the socio-ecological dimensions of each particular situation. The aim of this study was to evaluate the existence, extent and social characteristics of Human-Raptor Conflicts (HRC) in the Southern Yungas region in northwestern Argentina. We conducted 115 semi-structured interviews in 21 sites and analyzed attitudes and associations between sociodemographic variables and the existence of HRC. Forty percent of interviewees showed negative attitudes towards raptors, mainly with those species considered livestock predators rather than poultry predators. A total of 11 species were regarded as conflictive because of predation on domestic animals, of which Andean condors showed the highest conflict. The only socio-demographic factor affecting conflicts was livestock and poultry rearing, independently of age, gender and occupation of interviewees. The fact that only 8.7% of interviewees reported taking direct actions towards conflictive species indicates a relatively peaceful coexistence of people with raptors. Nevertheless, negative attitudes towards Andean condor together with their extreme susceptibility to any increase in non-natural mortality indicate the need of an integral conservation approach to tackle future threats for this species’ conservation in the area.

“…Though Amur Falcons are listed as Least Concern (Birdlife International 2016), the loss of so many birds runs contrary to the conservation practice of keeping common species common. In Argentina, Barbar et al (2016) suggested persecution was an important threat to the Chaco Eagle. Elsewhere in the Americas, the Guadalupe Caracara (Caracara lutosa) is now extinct, largely because of persecution by European settlers (Greenway 1967) and collection for scientific specimens (Abbott 1933).…”
