I'm currently watching a documentary on the mothman/thunderbird Chicago sightings in 2017. Immediately ran to your blog to see if you had mentioned it but apparently not.
I don't know that this even hit my radar to be honest. I remember there were rumors of a guy with a jetpack (?) getting in the way in O'Hare Airport's airspace, but I didn't think he'd ever been considered a mothman and I'm not even sure those reports hadn't been debunked. I don't ever remember hearing reference to a Chicago thunderbird.
I tried to google for some clarity but man, the cryptid hunters really went all in on this one and it's a hot array of breathlessly reported and intently uncited rumor. :D Trying to figure out a source for the "dozens of sightings and reports" is a bigger job than they pay me for. :D
