For buildings that don't have permanent bird strike mitigation measures built in, I wonder if temporary whitewash applied by window cleaners would help.
It seems to me that that would be an effective temporary solution, but would have to be re-applied following rain. The bigger problem would be cost. The building in the article is McCormick place which was hit pretty hard during Covid and is likely still recovering (financially.) But no business is likely to spend the $$$ to mitigate the issue unless they are forced. The bigger problem is that this is not the only bu…
I didn't realize it was McCormick place when I posted. That building is probably particularly bad because it's right on the shore of Lake Michigan (a bird migration superhighway). Ironically/tragically, the situation might have been made worse in recent years by the reestablishment of native plants in the immediately surround area. I'm certainly no expert, but I wondered if temporary whitewash might be more amenable to the building owner than something more permanent. It is a massive building complex, but might even only be necessary to do the north facing side. The roof overhang might allow it to stick around for a few peak-migration weeks.
