Toronto has had bird-friendly design guidelines since 2007. Surprised Chicago still hasn’t implemented a solution. https://www.toronto.ca/city-government/planning-development/...

Both Chicago and Illinois have bird friendly building ordinances but the building in question was built in 1960 long before they existed. It’s also massive so mitigations will take a long time to be applied.

Surely it cannot be too hard to slap 2 or 3 anti-collision decals on every window from the outside?

There are stickers on the building. It is a nearly 600000 square foot building and the exterior is all windows.

1000 birds don’t hit it _every day_ this was an exceptional even caused by specific conditions.

The facility is actively trying new lighting solutions to mitigate bird strikes as that’s the main issue.

To give a sense of the scale of this building: Part of the convention center empty: https://www.google.com/maps/@41.8535338,-87.6124521,3a,75y,6...

From what used to be Meigs Field. You have to back up quite a bit to see the entire building. It's very large, and right on the lake. https://www.google.com/maps/@41.8538295,-87.6090441,3a,75y,2...

A crew of window cleaners could hit it in under a week

It has stickers

[ethagknight]

Right... swing down and apply stickers. Yes I read the article.

You need more than 2 or 3 decals per window — there should be 2" or less of vertical space and 4" or less of horizontal space between markings (the 2" x 4" rule).

Chicago does have an ordinance requiring bird-friendly designs in new construction or renovations, but it was passed in 2022 and the convention center hasn't had window work done since then.

Wow only a few cities have replicated this. Is the associated cost of designing bird friendly buildings cost prohibitive? If so, need regulation to enforce this at state/local levels.

[yoyopa]

it's not cost prohibitive if you pay for it. but it's more expensive by a lot

This is SUCH an awesome and wonderful document. Thanks for sharing!
