This sounds wrong. Cornell University has the world's most advanced orinthology dept and operates eBird [0], the most complete and accurate animal observation database of any kind as well as the world's largest citizen science project.

There is no such alarm being raised by Cornell [1] and I don't see them listed as participants in that panel (a bad sign, by itself).

Instead of panicking about birds, just learn what's around you [2] and get an appropriate feeder.
