This heat map highlights bird collision hotspots in downtown Dallas with color coding, with red representing areas with the highest number of collisions. Each collision is also marked by a gray dot. Clicking on a dot reveals details, including bird species, collision date, and a link to the observation on iNaturalist. Lights Out Dallas has documented 3,052 building collisions in 107 bird species between 2021 and 2024. This map includes observations for 2,850 of these collisions. Please note: Some pinpoint locations may not perfectly match where the birds were found, as the map is based on data downloaded from iNaturalist. Lights Out Dallas relies on the efforts of dedicated volunteers to document collisions, and slight inaccuracies in locations may occur. Bird collisions are a widespread issue and the second greatest source of human-caused fatalities in birds in North America. The purpose of this survey is to identify collision-prone locations and explore opportunities for improvement. This grassroots effort aims to provide valuable data to building managers, fostering collaboration to address this challenge and reduce bird collisions. We explore opportunities to work with building managers toward practical solutions that benefit both birds and the community.
