My parakeet is a beast

well i have a parakeet(Paco). i let paco out of his cage today so he could fly around and get some exercise. then he flew into my room (wasnt expecting this) and head first into my rotating ceiling fan. than knocked him backwards about 5 feet but he kept flying around in circles. then he flew out of my room, down the hall, and head first into a window. the window unfortunatly is two stories off the ground. so he hit the window and fell straight down two stories onto a hardwood floor. so as i run downstairs im thinkin hes gotta be dead, but when i get to him hes still alive but live lying on the floor not looking so good. he couldnt even stand on my finger so i oicked him up and tried to put him on he perch in his cage. he could so he just plops down on the bottom. im thinkin hell be dead pretty quick but in like a minute he hops up off the floor of his cage and onto his perch. hes been acting like he normally does all day and seems to be perfectly fine, you cant even tell anything happened. so the moral of the story is that pet smart knows their shit and sells quality parakeets.
