“…This is also in keeping with Rayner (1988) who determined that the relatively small thin wings of the Columbidae make them among the bird groups most susceptible to collisions. In North and Central America, nocturnal migrants, grouses, falcons, hummingbirds, and passerines such as warblers, manakins, sparrows and thrushes were the most likely victims (Gelb and Delacretaz 2009, Breithaupt et al 2013, Klem 2014, Loss et al 2014, Menacho-Odio 2015.…”

“…We also found no difference between seasons, but this requires verification by long-term studies. In the northern hemisphere, collisions tend to increase during the spring and autumn migrations (Gelb andDelacretaz 2009, Kahle et al 2016). However, in Colombia, collisions occurred year-round but peaked in August and September (Ocampo-Peñuela et al 2016b).…”

“…However, our study suggests that their use is merely aesthetic and does not reduce the number of bird-window collisions, as desired. Therefore, we suggest that this tradition be abandoned and efforts should rather be encouraged to identify the factors most frequently associated with bird-window collisions (Gelb and Delacretaz 2009). Based on this, an effective protocol could be developed to incorporate the testing of a various interventions.…”

ABSTRACT. Bird-window collisions are a dramatic cause of bird mortality globally. In Latin America, statistics are generally very scarce and/or inaccessible so the frequency of such incidents is still poorly understood. Nevertheless, civilians have applied preventive methods (e.g. adhesive bird-of-prey decals) sparsely but, to our knowledge, no study has evaluated their effectiveness in Brazil. Here, we estimated the mortality rate of bird-window collisions and tested the effectiveness of bird-of-prey decals at preventing such accidents. We undertook daily searches for bird carcasses, presumably resulting from window collisions, near all buildings on a university campus over seven months. Adhesive bird-of-prey decals were then applied to the two buildings with the highest mortality rates and surveys continued for over 12 more months. The mortality rates before and after the application of decals and between seasons were then compared using Friedman test. We recorded 36 collisions, 29 around the two buildings with the highest collision rates 19 prior and 10 after our intervention with associated collision rates of 0.08 and 0.04 collisions/day. Although mortality was reduced by almost half, this difference was not statistically significant. The Blue-black grassquit, Volatinia jacarina (Linnaeus, 1766), and Ruddy ground dove, Columbina talpacoti (Temminck, 1810) suffered the highest number of collisions, followed by the Rufous-collared sparrow, Zonotrichia capensis (P. L. Statius Müller, 1776). Our bird-of-prey decals and efforts were insufficient to prevent or dramatically reduce the number of bird-window collisions. Therefore, we recommend that different interventions be used and additional longterm studies undertaken on their efficacy.

“…There are a number of factors that have been associated with increased frequency of daytime bird strikes. The importance of these factors can be assessed on a small geographical scale by measuring architectural characteristics such as building glass surface area (Klem et al 2009;Borden et al 2010;Bayne and Rawson-Clark 2012) or proximate landscape configurations (Hager et al 2008;Gelb and Delacretaz 2009;Klem et al 2009), or they can be assessed on a larger geographical scale by measuring neighboring landscape features over a broader geographical extent. The latter landscape features have largely been ignored in BWC studies.…”

Bird collisions with buildings are an increasing concern and yet understanding the factors contributing to collisions at the species level remains largely unknown. This gap in our knowledge of species-specific strike patterns hinders the development of accurate estimates for the impact of death-by-collision on bird populations and impedes on our ability to minimize its effects. Our study offers the first examination of the impact of environmental variables on birdwindow collisions at the species level. The Fatal Light Awareness Program Canada collected bird-window collision data in three distinct regions of Toronto, Canada during the migratory season of the years 2009 and 2010. Our results indicated that building percent window cover, exposed habitat cover, and cover of built structures significantly affect bird-window collisions. Multivariate analyses showed that the bird species that collided with buildings surrounded by a high level of urban greenery are species that typically occur in forested habitats and are foliage gleaners. In contrast, species that collided with buildings surrounded by a higher level of urbanization are species that typically occur in open woodland and are ground foragers. These results suggest that the composition of bird species colliding with buildings across various regions of the Greater Toronto Area is influenced by the local bird species community composition, by the configuration of the surrounding landscape, and by the levels of greenery around the buildings.

“…Over 30 years of research has documented that buildings and windows are the top killer of wild birds in North America (Banks 1979;Ogden 1996;Hager et al 2008;Klem 2009;Gelb and Delacretaz 2009). Structure collision fatalities may account for between 100 million and 1 billion birds killed annually in North America (United States Fish and Wildlife Service 2002; Klem 2009).…”

We express our appreciation to the Cities of Toronto, New York, and Chicago and the State of Minnesota, whose guidelines and standards provided a basis for these. Thanks also to the following people for their work to make the built environment safer for the winged animals who enrich our world, and with whom we share our City: This document is based in part on guidelines published by: New York City Audubon Society, Inc., May 2007; the Audubon Minnesota, May 2010; and an unpublished draft of the National Guidelines by the American Bird Conservancy.

RECOmmENDED ACTIONS AND BIRD-SAFE STEwARDSHIP 33Public Pigeons and sparrows are readily visible in San Francisco. These ubiquitous city birds are not shy about sharing our urban spaces. But the casual observer may be shocked to learn that our City's birds are much more diverse. There are about 400 species of birds in San Francisco; remarkably, this is nearly half the species in all North America (Kay 2009). For those who look, the shyer species are just around the corner. This is due in part to the diverse habitats of the Bay Area and its position on the coastal migration path, the Pacific Flyway. Some birds are well-adapted to urban life, and they may remain here as year-round "residents." Others are migratory, passing through the City southward in autumn en route to their winter feeding grounds, then returning northward in spring to establish territories in summer breeding grounds.There are special problems posed for birds living in or flying through cities. Over 30 years of research has documented that buildings and windows are the top killer of wild birds in North America (Banks 1979;Ogden 1996;Hager et al. 2008;Klem 2009;Gelb and Delacretaz 2009). Structure collision fatalities may account for between 100 million and 1 billion birds killed annually in North America (United States Fish and Wildlife Service 2002;Klem 2009). According to the leading expert, Dr. Daniel Klem Jr., this toll strikes indiscriminately culling some of ...
