Take Action Today
(June, 2026) We want to help Chicago residents ask the city council to create the mandatory bird-friendly building design ordinance that Bird Friendly Chicago has been working toward for several years.
Will you help us save birds?
There are two important actions that you can take right now. (And maybe more to come later.)
Thank you for speaking up for birds !
Bird-window collisions kill over 1 billion birds each year in the United States – and Chicago is a big part of the problem.
To address this conservation crisis head on, Alders Maria Hadden, Brian Hopkins, and Ruth Cruz have sponsored a bird-friendly building ordinance that was introduced by Alder Hadden (see co-sponsors), but we need more support from the council for it to pass.
Time is of the essence as we would like to see the new law adopted before budget season gets under way in October. We need as many people as possible to contact their elected official – or the person who represents the district where they work – to ask them to support this ordinance.
This is where you come in!
Action 1: Send a letter
If you live or work in Chicago, please use the form linked below to ask your elected official to co-sponsor a new mandatory bird-friendly building ordinance.
- If you live in the city, enter your home address.

Action 2: Speak With your alderperson
If you live and/or work in the City of Chicago, you can directly advocate for this ordinance in a couple of ways:
- Call Your Alderperson: You can find their number here. If you want some tips on what you might say, click on “Send a Letter Now” above for some ideas.
