چکیده

Bird collisions with windows are an important conservation concern. Efficient mitigation efforts should prioritize retrofitting sections of glass exhibiting the highest mortality of birds. Most collision studies, however, record location meta-data at a spatial scale too coarse (i.e., compass direction of facing façade) to be useful for large buildings with complex geometries. Through spatial analysis of three seasons of survey data at a large building at a university campus, we found that GPS data were able to identify collision hotspots while compass directions could not. To demonstrate the broad applicability and utility of this georeferencing approach, we identified collision hotspots at two additional urban areas in North America. The data for this latter exercise were collected via the citizen science database, iNaturalist, which we review for its potential to generate the georeferenced data necessary for directing building retrofits and mitigating a major source of anthropogenic bird mortality.

Patterns of bird-window collisions inform mitigation on a university campus

Bird-window collisions cause an estimated one billion bird deaths annually in the United States. Building characteristics and surrounding habitat affect collision frequency. Given the importance of collisions as an anthropogenic threat to birds, mitigation is essential. Patterned glass and UV-reflective films have been proven to prevent collisions. At Duke University's West campus in Durham, No...

Bird-Window Collisions at a West-Coast Urban Park Museum: Analyses of Bird Biology and Window Attributes from Golden Gate Park, San Francisco

Bird-window collisions are a major and poorly-understood generator of bird mortality. In North America, studies of this topic tend to be focused east of the Mississippi River, resulting in a paucity of data from the Western flyways. Additionally, few available data can critically evaluate factors such as time of day, sex and age bias, and effect of window pane size on collisions. We collected a...

NEW PERSPECTIVES ON BIRD-WINDOW COLLISION: THE EFFECTS OF SPECIES TRAITS AND LOCAL ABUNDANCE ON COLLISION SUSCEPTIBILITY by

2 EXECUTIVE SUMMARY Birds provide substantial ecosystem services such as pest control and act as indicators of environmental health. Diverse, widespread, and conspicuous, they have also helped advance our understanding of how ecological communities function. Unfortunately, human activities are now adversely affecting many bird species, driving populations downward. While major threats like habi...

Event-driven Change-detection in Urban Environments Using Sar

SAR sensors are able to operate under nearly all weather conditions, at daylight or in the night. This is especially beneficial for event-driven applications, like time-critical change-detection for disaster management. Unfortunately, SAR systems suffer from occlusions and ambiguities, especially in urban areas. Additionally, due to layover and foreshortening effects, the geo-referencing of SAR...
