This is why you shouldn't release live birds indoors.
Apparently the eagle was set free as Oral Roberts University students were celebrating at a mass as part of a special spirit day chapel service held to ring in the new school year. As chants of 'U-S-A' build in the chapel, the bird makes an ill decision and tries to escape outdoors, not realising there's a pane of glass in the way. Apparently the eagle was a little stunned but is doing fine now, the poor little big guy.
