ok i've done some extensive looking into it
at this point, i think i'm able to hypothesize that you may have a scissor-tailed flycatcher that's broke into your room (possibly kicked down the door, maybe broke your locks, or opened up your window and climbed in if you left it unlocked. OP, i advise you check all of your windows & doors)
this is also the national bird of oklahoma, so do NOT attempt to make contact or confront it. call the police immediately after confirming you've seen it.
