Power lines endanger birds around the world, as a large number of them are killed every year through electrocutions and collisions. This problem can have severe consequences at population level, particularly for threatened species. While this threat has been widely studied in different parts of the world, information from South America is scarce. H...

... found only 15 scientific articles that reported or evaluated birds affected by collision or electrocution with power lines in South America (Table 1, Fig. 1). Additionally, 41 newspaper reports referred diverse bird species interaction with power lines ( Table 2). The scientific publications reported 61 bird species affected by collisions and electrocutions with power lines, while 22 species come from newspaper reports (Tables 1, 2, Fig. 2). The newspaper reports did not provide data on ...

... the last decade, which highlights there is some concern in both scientific and lay people. We showed that only 6 out of 13 of the countries in South America have addressed some aspects of this conservation problem in a scientific study (Fig. 1, Table 1). However, information provided by newspaper reports shows that the problem is widespread and that in most countries of South America -although probably in all -, bird collisions and electrocutions with power lines represent an important source of avian mortality at present (Fig. 1). Moreover, most scientific and anecdotal information ...

Moreover, most scientific and anecdotal information from this sub-continent comes mainly from a few countries such as Argentina, Brazil, Peru and Chile. This is probably driven, among other things, by the higher development of socio-economic indicators of these countries (Guil and Pérez-García, 2022), including the increase of the ...

... The Crested Caracara was below a concrete pylon with a wood crossarm and vertical pin insulators, and was diagnosed as electrocuted based on the presence of burned primary feathers (Fig. 2). The third electrocuted Crested Caracara was a report we found via an internet search including the terms Crested Caracara, caracara, and carancho as in Rebolo-Ifrán et al. (2023). That search indicated the electrocution of an adult Crested Caracara building a nest on a concrete pylon with a transformer reported in a newspaper from Santa Fe Province on 2 March 2023 when the electrocution caused an outage in the town of Oliveros (32 34 0 00 00 S, 60 51 0 00 00 W; Información Regional 2023). ...
... Furthermore, to our knowledge, there is no published study on the effects of stock tanks on Argentinean wildlife except for a reference to Chaco Eagle (Buteogallus coronatus) drownings (Sarasola et al. 2022) and a study on passerines (Petracci and Carrizo 2022). Regarding electrocution, a recent review has identified a limited number of studies assessing electrocution or collision of birds with power lines in South America (Rebolo-Ifrán et al. 2023). Therefore, these two mortality sources for wildlife are likely understudied and underestimated on the continent. ...
... Regulations and recommendations for the building of water reservoirs for livestock should be developed and extension work among ranchers should promote the application of such mitigation measures to reduce this source of mortality for caracaras and other wildlife. Rebolo-Ifrán et al. (2023) reported two possible cases of electrocution in caracaras, based on newspaper articles. In both cases, the published information mentioned electric outages caused by the caracaras building nests on power pylons, although there was no specific mention of the birds being electrocuted. ...
... To assess the knowledge on unnatural mortality of raptors in Nepal, we conducted a revision of scientific articles, newspaper reports, and social-media posts to compile records (Rebolo-Ifrán et al. 2023). The raptor mortality recorded on opportunistic observation was also included. ...
Raptors play a unique role in ecosystem services and are regarded as effective indicators of ecosystem health. In recent years, varieties of anthropogenic factors have threatened the majority of raptor species worldwide. Nepal is considered a global hotspot for threatened and declining raptor species, but there is limited information on the direct human threats to the raptor populations living in the country. In this paper, we identify important anthropogenic threats to raptors in Nepal based on raptor mortality data collected by powerline surveys and from monitoring of GPS-tagged raptors, complete various reports, and social media. We found that powerlines, poisoning, and persecution, mainly shooting, are significant threats to raptors in Nepal that were largely overlooked previously. We report 54 electrocuted raptors affecting eight species, 310 poisoned raptors of 11 species, and five persecuted raptors of four species; among them vultures are the most affected (>88%). Based on our findings, to safeguard the future of Nepal’s raptors, we propose the retrofitting of power poles and the use of flight diverters on powerlines in the most affected areas to reduce raptor interactions with powerlines, as well as an effective conservation education programme to prevent the use of unintentional poisoning.
