“…A substantial number of bird species known to occur in Monteverde were documented as victims of bird-window collisions. Even though the number of species recorded in this study is much higher than the 57 species registered in Reserva Particular do Patrimônio Natural Santuário do Caraça, Minas Gerais, an Important Bird Area in Brazil (Santos et al, 2017) and 25 species in a rural area in Colombia (Ocampo-Peñuela, Peñuela-Recio, & Ocampo-Durán, 2015), it likely underestimates the true number. Some of the factors for the presumed underestimation of our results are: a) in museums, it is not mandatory for the specimen tag to indicate the cause of death of birds.…”

“…We found that most species affected by window collisions in the study area were residents. Santos et al (2017) and Ocampo-Peñuela et al (2015), also found mostly resident species in their studies in rural conditions in the Neotropics. It is possible that the high density of year-round resident birds of Monteverde, and the deception caused by reflection of vegetation in windows, causes the high mortality of resident individuals Klem et al, 2009;Borden &Lockhart, 2010).…”

“…We documented window-kills in endemic Neotropical families, including guans (Cracidae), toucans (Ramphastidae), motmots (Momotidae), and manakins (Pipridae). Ocampo-Peñuela et al 2016and Santos et al (2017) also found species of these families in their studies in rural areas in the Neotropics. The Northern Emerald-Toucanet was cited as one of the species most often reported as victim of window collisions.…”

“…While many studies document bird collisions in the United States and Canada, relatively few studies have taken place in the Neotropics; these include studies from Colombia (Agudelo-Álvarez, 2006;Agudelo-Álvarez, Moreno-Velasques, & Ocampo-Peñuela, 2010;Ocampo-Peñuela et al, 2016), Costa Rica (Graham, 1997;Menacho-Odio, 2015;Oviedo & Menacho-Odio, 2015), Mexico (Cupul-Magaña, 2003;Gómez-Moreno, Herrera-Herrera, & Niño-Maldonado, 2018), and Brazil (Briske, Campos-Silva, & Piratelli, 2017;Santos, Ferreira, & Ferreira, 2017). Studies conducted in Important Bird Areas (IBA) are even more infrequent (Santos et al, 2017).…”

Worldwide, billions of birds die annually due to window collisions. Nevertheless, few accounts document bird-window collisions in the Neotropics. In this study, we document species that collided with windows in Monteverde, Costa Rica, and describe their ecological and conservation status. We gathered information from different sources, including data from museum records and accounts by Monteverde residents who participated as “citizen scientists” between May 2014 and December 2017. We conducted carcass searches between March 2015 and February 2016. We classified window-strike species by migratory, forest dependence, trophic guild, weight, abundance, conservation, and endemism status. We registered 103 species striking windows in Monteverde, which includes 98 of 267 species known to occur in three life zones in Monteverde and five not registered in the area. Window strike casualties’ frequencies differed by species, trophic guild and migratory status. Most window victims were residents, small, insectivorous, considered common or fairly common, with declining population trends. The families with the most species represented were Parulidae (14 spp.), Trochilidae (13 spp.), Turdidae (10 spp.), and Tyrannidae (9 spp.). Most species were passerines (Order Passeriformes) (71 spp.). No hawks or vultures were found colliding with buildings. The three species most commonly killed by windows were frugivores: Swainson’s Thrush (Catharus ustulatus), Northern Emerald-Toucanet (Aulacorhynchus prasinus), and Black-faced Solitaire (Myadestes melanops). Among window-kills were five species whose status on the IUCN Red List are Near Threatened and one Vulnerable, including the Resplendent Quetzal (Pharomachrus mocinno) and the Three-wattled Bellbird (Procnias tricarunculatus). Six species are listed as in danger of extinction and four are listed as species with reduced populations by the National System of Conservation Areas for Costa Rica (SINAC). 12 endemic species are strike casualties. The premontane wet forest is the life zone where more species were found (n=64 spp.), followed by the premontane moist forest (n = 49 spp.) and the lower montane wet forest (n = 31 spp.). These findings demonstrate the urgent need for conservation measures to mitigate bird mortality due to window collisions. Promoting use of methods to protect birds from windows should be an important goal for this IBA and the rest of Costa Rica. We also recommend collecting data in order to increase understanding about bird window collisions.

“…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.
