Monday’s meeting of the McPier board was dominated by discussion of the mass death of 1,000 birds in a single day, killed after colliding with McCormick Place. Bird conservationists want a solution in place by spring migration.

Sterling Bay’s first completed structure at its $6 billion Lincoln Yards riverfront development was constructed with bird-friendly glass. The use of the material is one of several features intended to minimize the sorts of deadly bird collisions Chicago just witnessed in record numbers.

While the full tally of dead will never be known, wildlife advocates are certain of one thing: The vast majority of bird losses in the past week were preventable.

Chicago is one of the deadliest cities for migrating birds and Thursday’s “insane abundance of migratory action” led to “insane mortality,” birders said. The remedy is as simple as flipping off a light switch.

If the embattled online retailer still wants to build its tower in Skokie, the company will have to start the approval process back at square one, village trustees said.

If a casino is coming to the riverfront, publicly accessible open green space should be a priority, as well as considerations for wildlife habitat, environmental advocates say. And the buildings themselves should be held to the highest standards of sustainability and climate resiliency.

In response to concerns about putting a see-through glass tower in the path of migrating birds, Carvana revised its plan to incorporate bird-friendly components. Critics called the proposed mitigations “woefully inadequate.”

Nearly 600 million birds are killed annually in North America due to collisions with buildings. A new Illinois law mandates bird-friendly design for state buildings.

Since 2003, a group called the Chicago Bird Collision Monitors has made it their mission to collect birds that have been killed or injured after striking buildings and other structures.
