Had a buddy in College who worked on a migration study for Red Wing Blackbirds. They dusted whole flocks from different locations in the upper midwest with corresponding colored glow powders from aircraft and then went to Arkansas, Louisiana, and Mississippi to find out which birds migrated from which location. They'd shoot Red Wings with shotguns and then look for glow dust under a special light. Almost everywhere they collected birds, someone would come by and ask what they were going to do with the pile of Black Birds when they were done and ask if they could have them to eat. He said they rarely threw any of the birds away as most of them were taken by folks to eat. At least they weren't wasted I guess.
