Red-winged blackbirds are not afraid to stand up to any large bird who flies into their area, and will use any means necessary to drive them off. This usually involves the blackbird being as annoying as possible.
“One took a couple scraping runs by him, but the other one — it was dozens of times that the bird would try to pull a feather out of his back,” Rohling said. “The osprey squawked and flapped his wings, but he tried to ignore them as much as he could.”
