I think they should just turn the lights off on glass skyscrapers during the busiest weeks of migration, which is only about 3 weeks a year. I believe Chicago does this already on some of its tallest towers. I used to belong the Houston Audubon Society and we would go around picking up dead birds and tallying how many died and of what species in downtown Houston every Spring and Fall. The numbers were staggering, we would find thousands of dead warblers and other migratory songbirds. Skyscrapers pose just as much of a threat to songbirds as does forest fragmentation and habitat loss and that was hard to cope with being a fan of skyscrapers and a birdwatcher.
