“…Our knowledge regarding bird‐window collisions in Mexico is limited to two studies that list colliding birds at university buildings (Cupul‐Magaña, 2003; Gómez‐Moreno, Herrera‐Herrera, & Niño‐Maldonado, 2018) and one that assesses some ecological variables related to collisions (Gómez‐Martínez et al, 2019). In this study, we performed a citizen science survey of bird‐window collisions at seven buildings in the university campus of the National School of Higher Studies (referred to as ENES hereafter due to its acronym in Spanish) of the National Autonomous University of Mexico (referred to as UNAM hereafter due to its acronym in Spanish) located in the city of León (Guanajuato).…”

Bird‐window collisions have been estimated to be among the most important sources of bird death. Despite increasing knowledge in Latin America, our understanding of this phenomenon is still incipient, with research performed in Mexico limited to a handful of studies. Here, we present the results of a citizen science effort focused on bird‐window collisions at seven buildings in the university campus of the National School of Higher Studies (ENES) of the National Autonomous University of Mexico, located in the city of León (central Mexico). Our main goal was to describe seasonal patterns of bird‐window collisions and their relationship with building traits (i.e., building height, window area) through citizen science monitoring strategies. Our results showed that collisions were higher in two of the seven studied buildings, with two bird species recording almost half of the total collisions: Clay‐colored Sparrow (Spizella pallida) and Indigo Bunting (Passerina cyanea). Seasonally, April was the only month to differ from the rest of the studied months, showing significantly higher rate of bird‐window collision. Regarding building traits, only building height was related to the number of recorded bird‐window collisions. In sum, our study provides findings from an understudied area, showing the value of citizen science approaches to generate knowledge on a deadly phenomenon. Notably, besides the potential drawbacks and importance of generating this kind of information, our project raised awareness on the topic across the entire campus community, from the students and academics to the administration, highlighting the potential for social impact with these kinds of projects.

“…Fortunately, although it is still limited, there is a growing interest in studying this threat in Latin American countries. Some studies exist for Brazil 28,29 , Colombia 30–32 , Costa Rica 33–35 and Mexico 36–38 . However, there is rare or nonexistent data for other large countries with high bird diversity, such as Argentina, were around 10% of the world’s bird diversity inhabit 39,40 .…”

Bird-window collisions are one of the main causes of avian mortality worldwide, with estimations reaching up to almost one billion of dead individuals annually due to this cause in Canada and the USA alone. Although this is a growing conservation problem, most of the studies come from North America, evidencing the lack of knowledge and concern in countries with high biodiversity and growing population development. Our objectives were: (1) to estimate the current situation of bird-window collisions in Argentina, a country with around 10% of the world’s avian biodiversity, and, (2) to identify drivers of bird-window collisions at a national and local scale, focusing on a city surrounded by a protected area. We used a citizen science project called “Bird-Window Collisions in Argentina” that consisted of an online survey that collected data on collision metrics and risk factors. We found that more than half of participants reported at least one collision during the last year, suggesting this issue is common and widespread. In addition, our data show that the number of windows and the presence of vegetation reflected in windows are factors that strongly influence the risk of collision at national scale. On the other hand, the environment surrounding buildings affects the rate of bird-window collisions at local scale, being greater in buildings surrounded by tall vegetation than in buildings surrounded by a greater proportion of urbanization (human-made structures). We call for attention on a topic that has been poorly evaluated in South America. We also encourage future scientific studies to evaluate additional risk factors and mitigation strategies accordingly, to provide a better understanding of bird-window collisions particularly in a highly biodiverse region as South America.

“…Fifty-nine of the species identified in this study have not been previously reported as affected by these structures in Mexico. These numbers suggest that power lines represent the cause of mortality affecting the widest range of bird species in the country, even greater than window collisions (71 species; Cupul-Magaña, 2003; Gómez-Martínez et al, 2019; Gómez-Moreno et al, 2018; Uribe-Morfin et al, 2021), and collision with wind turbines (29 species; Cabrera-Cruz et al, 2020; Uribe-Rivera et al, 2018). This does not mean that power lines are the main anthropogenic cause of direct bird deaths in the country, but it does reflect the enormous impact that these structures have on Mexican avifauna.…”

Background and Research Aims Power lines are one of the main anthropogenic causes of bird mortality on a global scale, but research is scarce in some countries with a high diversity of birds, such as Mexico. In this study, we assessed the impact of bird collisions and electrocutions with power lines on avian communities at three wind farms located in three different states in Mexico. Methods Carcass searches were carried out at sites in Tamaulipas (4 months in 2021), Guanajuato (2 months in 2020, 4 months in 2021), and Oaxaca (55 months from 2014 to 2021). Results A total of 579 bird carcasses from 65 different species were recorded. The White-winged Dove ( Zenaida asiatica) was the most frequently found species (282 records) across the three sites. When considering the number of species identified per family, Icteridae had the highest number of species at the Oaxaca site, Columbidae and Passerelidae at the Tamaulipas site, and Anatidae at the Guanajuato site. At the order level, Passeriformes had the highest number of species at the Tamaulipas and Oaxaca sites, and Anseriformes in Guanajuato. Of the total species recorded, 12 are within some category of risk according to Mexican legislation and the IUCN Red List, and 18 are migratory species. Conclusions Our results, together with evidence from previous studies, indicate that power lines represent one of the main causes of anthropogenic mortality in Mexico in terms of the number of affected bird species. Further research is urgently needed to explore the effect of power lines on bird populations in the country, particularly those at risk of extinction, and migratory species. Implications for Conservation The high diversity of species found to be affected in this study highlights the wide-ranging impact of these structures and the need to implement mitigation strategies at the three sites studied, particularly for the most affected species, the White-winged Dove ( Zenaida asiatica).
