Current Season Information

We are continuing the Window Strike Survey in Spring 2024! Our seasons are now extended to two months to better encompass both species groups that migrate through here vs previous seasons (Spring = mostly continental and Fall = mostly neotropical)

The main season will run from March 5th to May 5th

We once again are asking for volunteers to help walk morning and evening routes on campus to monitor these bird strikes for vital data. No prior experience is necessary - anyone can walk a route! The shifts are run twice a day on both the North and South Quad (the morning route is 7-9 am and the afternoon route is 5-7 pm).

If you have any questions, please reach out to our email: birdstrikes.uiuc@gmail.com

Make sure to walk with one of the project leaders before you walk alone! Please email Sarahj7@illinois.edu to set up a time!
