Video: Moment falcons swoop on researchers caught on camera With only wooden shields and helmets to protect themselves, a group of researchers moved in to tag a pair of falcon chicks in a nesting box on the roof of Toledo University clock tower in Ohio. The falcon chicks were temporarily removed from the nest to be weighed, have blood samples taken and numbered bands fitted on their legs for tracking and identification. However, fearing for their young, the chicks' protective parents swooped in on the researchers. The team from The Ohio Department of Natural Resource's Division of Wildlife wore helmet cameras which captured the terrifying moment the birds flew at them with outstreched talons. Their footage shows the conservationists fending off the attacks with wooden shields as they shouted warnings to eachother of the direction the birds were coming from. The adult falcons only ceased their attack once the chicks were placed safely back in the nesting box.
