CHICAGO (WBBM NEWSRADIO) -- Bird advocates are asking for more bird-friendly measures for buildings downtown after thousands of migrating birds ended up dead in Chicago.
In just one night, 1,000 birds crashed into the McCormick Place Lakeside Center on the shore of Lake Michigan last week.
Annette Prince, Director of Chicago Bird Collision Monitors, said the building is a recipe for all things that are dangerous for birds.
"Ever since that building was constructed on the lakefront, it has posed a serious hazard to birds. Through the years, the continual number of bird strikes has added up to tens of thousands of birds."
Prince said a combination of factors likely contributed to the extraordinary number of deadly collisions.
She would like to see the city switch to bird-friendly glass being used on new construction downtown, as well as buildings being required to turn off their lights overnight during the high migration season that ends close to Thanksgiving.
"We know that when we say we collect 5,000 birds a year in downtown Chicago, there could be 10 times as many birds that really get hurt, but they were on rooftops and awnings and places that we didn't get to in time," Prince added.
