About Bird-window collisions & the Bird Collision Corps

Bird-window collisions kill over 1 BILLION birds every single year in the United States. That shocking number can be drastically reduced when communities work together to ensure windows that are most problematic for birds are treated to prevent collisions. Typically, the first step in making change in your community is to collect data on when, where, and to what extent the problem is happening. That’s where the Bird Collision Corps (BCC) program comes in. People in power typically need data to demonstrate that there is a problem. BCC can facilitate a way for your community to collect those critical data.

The BCC originally started in 2018 in Madison, WI as a partnership between Southern Wisconsin Bird Alliance and the University of Wisconsin-Madison’s departments of Forest & Wildlife Ecology and Facilities Planning & Management. The goal was to study the top 10-15 buildings identified as likely collisions hotspots, document the number of birds hitting their windows, come up with solutions to fix problem areas. The program has been a tremendous success in terms of volunteer engagement, survey site growth (now surveying at 12+ locations around the Madison area), and window mitigation efforts. Learn more here! The biggest success story is that BCC data helped implement the Madison Bird-safe Glass Ordinance in 2020, with an identical ordinance passing in Middleton in 2024.

How Bird Collision Corps works: The Nitty Gritty

TIMING: BCC runs for about 6 weeks during spring and fall migration (in Madison, it runs mid-April to June 1, and mid-September to November 1). The survey period should be set to capture the bulk of spring and fall bird migration through your area. Surveys should be completed by 9:30 AM to minimize the number of birds that are removed by scavengers.

REGISTRATION: Volunteers sign up for a specific site on one or more days of the week and to survey at their site on designated day(s) during the survey period. For example, if Susan signs up for Mondays at the bank, she surveys every Monday at the bank before 9:30 AM each week during the survey period.

FINDING BIRDS: If a volunteer finds a dead bird, they collect it with a plastic zip-lock bag and fill out a data form. The bird must then be frozen (either at home, or at an identified drop-off site). When a volunteer finds a live bird, they collect it in a cloth or paper bag, fill out the data form, and bring it to a local wildlife rehabilitator.

DATA COLLECTION: Whether the bird is dead or alive, the volunteer should document the collision and submit an observation form using an online data portal. We recommend using iNaturalist because it is free, allows for uploading photos and GPS location tagging, allows for customized forms, allows the online community to help identify birds to species, and facilitates a collaborative and engaged feeling among volunteers. Here is an example iNaturalist BCC project. Survey123 (ArcGIS), Global Bird Collision Mapper, or dBird.org are additional options.

 

Starting your own BCC program

 

Marketing Materials you can use

Recruiting volunteers and making the issue of bird-window collisions a more commonly understood problem takes time and effort. But there’s no need to recreate the wheel! Here are some graphics, videos, and text snippets you can copy, paste, and modify for your own use. Text in [brackets] should be edited by you!

 

Collisions Outreach Toolkit

We offer digital and actual materials you can use to promote bird-safe windows in your community. Check out our Collisions Outreach Toolkit page for a set of Powerpoint slides you can use, printable handouts, newsletter articles, a form you can fill out to request a box of Feather Friendly dots to create an example window, and more!

Join the Bird Collision Corps to make a difference for birds this [fall]!

You'll help study where birds are hitting windows in [the Madison area]—we use this data to work with building owners to find solutions for problem windows. Surveys are once a week in the mornings (before 9:30am) from [September 15 to November 1].

Learn more and sign up at [swibirds.org/bcc]

Thank you to all of our volunteers and partners! Birds are better off because of you!

[FALL] SURVEY PERIOD: [SEPT. 15 - NOV. 1]
MADISON, WI AREA

Weekly surveys, approx. 1 hour per week

Sites include [UW-Madison, Madison College, Henry Vilas Zoo, Verona Public Library,] and others!

Volunteer today [use your link]

Window collisions are the second leading cause of bird deaths directly resulting from human activities. The good news is that this is a fixable problem, but we need your help to study where birds are hitting windows in [the Madison area].

The Bird Collision Corps [use your link] is a group of volunteer community scientists (that's you!) who document the locations, frequency, bird species most effected by window collisions at your program sites during migration. With the data collected, we look at which windows are most problematic and work with building owners to fix that problem. The [Fall 2025] survey period is [Sept. 15 - Nov. 1], and we're looking for volunteers.

No expertise is required. We'll provide you with all the training and materials you'll need.

We need your help!

If you're interested in joining, follow these steps:

  1. Read more about the project: swibirds.org/bcc [use your link]

  2. Pick which site and day you want to survey and sign up here: swibirds.org/bcc-sign-up [use your link]

  3. Watch the training videos online at your convenience before [Sept. 15].

  4. Survey your site once a week on the day you choose from [Sept. 15-Nov. 1].

  5. Submit your data using the free data portal app we provide.

We'll provide you with all the training and materials you'll need. Bird Collision Corps is a great way to contribute to bird research and conservation close to home!
