Speaker 1: You're listening to Wbez this time of year, millions of birds cross Illinois each night in their spring migration north, but some will never reach their destination. Instead, they'll hit the windows of Chicago skyline. The City of Chicago is updating its policy for sustainable building development to help prevent these collisions. But some advocates say it's not enough. Joining us now is Nara Schomberg who reported on this for the Chicago Tribune. Thanks for joining us. Thanks for having me, Nara. The city's updated sustainable development policy is currently in draft form and it's available for public comment until May 15th. But can you tell us what it says about bird friendly design?

Speaker 2: Yes, this is a policy that requires some developers to choose from a menu of sustainable design options. Uh things like energy efficiency and the menu items are awarded points. You need a certain number of points to get permission to build or renovate. So now we have the policy update the first since 2017 and it says that you can get more points for choosing bird safety menu options, things like pattern glass that prevent birds from crashing into buildings.

Speaker 1: You actually talked to Annette Prince who's the chair of the Bird Friendly chicago Coalition. And she was a little disappointed with the draft policy. How come

Speaker 2: she is disappointed? She and other bird advocates say it's not enough to make bird safety an option on a menu when thousands of migrating birds are dying each year in chicago, they want requirements. And they also say that when bird safety is just one of many menu options, developers are unlikely to choose it. They'll go with something more familiar.

Speaker 1: Can you tell us how the city has responded to these concerns?

Speaker 2: The city says, look, the bird safety measures are getting a lot more points under the new policy in one case, three times as many points. And they also say that a policy like this isn't really the right place for a bird safety design requirement that would better be done. They say with an ordinance, a local law with a city council vote behind it.

Speaker 1: This issue of course, came to a lot of people's attention last fall when more than 900 birds died in one day after they crashed into mccormick Place. Lakeside Center are the owners of that building specifically taking any action to prevent collisions in the future.

Speaker 2: I I did talk to mccormick Place Lakeside and they, they said they acted really quickly reached out to experts and they now have a plan in place to install $1.2 million of bird safe glass. And they're hoping to do that by the fall migration season. But it, of course, it's not just the mccormick Place, Lakeside, this is a city wide problem.

Speaker 1: Do you mind telling us a little bit about how Chicago's policy compares to other cities? Lots of cities have migrating birds. How do we compare to them?

Speaker 2: I would say we're sort of in the middle. Um, some cities including New York, San Francisco, Skokie and Evanston are leaders. They have ordinances requiring at least some bird safety design. We don't have that at this point.

Speaker 1: I've been speaking with chicago Tribune reporter, Nara Schomberg about policies to protect migrating birds. Thanks for joining us today. Oh, thank you. This is Wbez.
