Problem Statement

Most North American birds migrate south during the fall, and back north during the spring while trying to avoid the harsh winters. Some species fly all the way to Central and South America, while some others migrate within the North American continent and call Durham their wintering home.

Collisions against man-made structures are the second biggest threat to migratory birds, after cats, causing an estimated 100 million to 1 billion bird deaths every year in the United States alone (Klem Jr. 1979, Loss et al. 2014). These estimates are rough because window strikes haven’t been quantified in most of the country. However, rough at it is, this means that preventing bird-window collisions would help a significant amount of birds, and everyone can help!

Duke University is located on the Atlantic Flyway, a route taken by many migratory birds during their amazing journeys (did you know some birds migrate 35,000 km roundtrip?). Through informal censuses, and thanks to the collaboration of many Duke fellows, we have concluded that window strikes are an issue for birds at Duke.

How will we solve this problem?

First, it is very important to know which buildings pose the biggest threats to birds. It is also important to know how many birds are victims of these collisions, and which species. Then, we will work with the Duke administration to install bird deterrents on present building and to design all new buildings to be bird-friendly.

  1. Hello; I noticed that you suggest folks enter bird collision reports in iNaturalist. As another option, I invite you to look at the FLAP Mapper, a site dedicated strictly to the reporting of bird collisions with windows, globally. We have seen a marked increase int he number of collisions entered since the site was launched just over one year ago. The citizen science project is designed to show the public that window collisions happen everywhere, not just in North America. Here is the link:
    If anyone has any questions, please give us a call or email : or 416-366-3527. Thank you.

    1. Thank you! We do know the site. However, we think i?Naturalist is easier for students because they can do it from their phone. does this site also have a phone App? Most of our volunteers are students that probably won’t take the time to upload a picture and enter information into a website, but are happy to snap and immediately upload the pictures to iNat. We look forward to further development of the tool you mention and to using it. Thanks
