“…All the other bird species have a conservation status of Least Concern ([ 32 ]; Appendix A). Fatalities of Inca dove were reported in five of the seven studies where bird fatalities were found, with the majority of fatalities (46.2%) at the Northern Wind Farm in Mexico [ 40 ]. Turkey vulture and common ground dove were reported in four of the studies, with the majority of fatalities (70.6% and 75.0%, respectively) at La Venta II in Mexico [ 37 ].…”

“…The remaining families had eight fatalities or less each. A minimum of 983 bat fatalities from at least 40 species were reported, with number of fatalities per study ranging from zero at the Western Wind Farm in Mexico [ 40 ] to 336 at Osório Wind Farm in Brazil ([ 41 ]; Appendix B). Mexican free-tailed bat ( Tadarida brasiliensis [I. Geoffroy, 1824]) and Davy's naked-backed bat ( Pteronotus davyi Gray, 1838) were the bat species with the majority of fatalities (274 and 219; respectively) reported across studies, followed by far by ghost-faced bat ( Mormoops megalophylla [Peters, 1864]; 62 fatalities).…”

“…With the exception of two Near Threatened bat species (lesser long-nosed bat [ L. yerbabuenae Martínez and Villa-R, 1940] and red fruitbat [ Stenoderma rufum Desmarest, 1820], with five and three fatalities, respectively) all other bat species have a conservation status of Least Concern. Fatalities of Mexican free-tailed bat were reported in all but two projects (Northern and Eastern wind farms; [ 40 ]), with the majority of fatalities (89.4%) reported at the Osório Wind Farm in Brazil [ 41 ]. Velvety free-tailed bat ( Molossus molossus [Pallas, 1766]) was also reported in all but two studies (Sierra de Los caracoles in Uruguay and Los Cururos in Chile), with the majority of fatalities (30.5%) reported at La Venta II in Mexico [ 37 ].…”

Most post-construction fatality monitoring (PCFM) studies to date have focused on North America and Europe, and this information has been used to assess the impacts of large-scale wind energy on birds and bats. A comprehensive review of wind-wildlife fatality information is still lacking for Latin America; however, given the current installed capacity and the projected increase of wind energy production across Latin America, it is important to fill in the knowledge gap on impacts to wildlife. To provide a current summary of known impacts to birds and bats in Latin America and to identify gaps on this important information, we compiled, reviewed, and synthesized bird and bat fatality information at wind energy projects in the region. Our literature search resulted in 10 references relevant to the scope of this review, six of which provided number of fatalities by species and the type of PCFM search being conducted, meeting our criteria for inclusion in fatality summaries. From this pool, we found that Passerines composed the majority of bird fatalities, with no Threatened bird species reported. The bat family Molossidae composed the majority of bat fatalities, with one Threatened bat species reported. Our review of all studies and focused assessment of only those studies with fatality summaries indicated differences in the amount of information and level of detail related to bird and bat fatalities at wind energy projects in Latin America. Due to the taxon-specific nature of collision risk with wind turbines for birds and bats, it is difficult to make a general impact assessment of wind energy development on birds and bats in Latin America, especially given the limited information available. However, this summary can be used as a starting point to inform conservation efforts aiming at avoiding, minimizing, and mitigating impacts of wind energy development on birds and bats and future, standardized results would enhance our ability to do so.

Wind as a clean and renewable energy source has been used by humans for centuries. However, in recent years with the increase in the number and size of wind turbines, their impact on avifauna has become worrisome. Researchers estimated that in the U.S. up to 500,000 birds die annually due to collisions with wind turbines. This article proposes a system for mitigating bird mortality around wind farms. The solution is based on a stereo-vision system embedded in distributed computing and IoT paradigms. After a bird’s detection in a defined zone, the decision-making system activates a collision avoidance routine composed of light and sound deterrents and the turbine stopping procedure. The development process applies a User-Driven Design approach along with the process of component selection and heuristic adjustment. This proposal includes a bird detection method and localization procedure. The bird identification is carried out using artificial intelligence algorithms. Validation tests with a fixed-wing drone and verifying observations by ornithologists proved the system’s desired reliability of detecting a bird with wingspan over 1.5 m from at least 300 m. Moreover, the suitability of the system to classify the size of the detected bird into one of three wingspan categories, small, medium and large, was confirmed.
