Wow... the deer certainly seemed charged up on adrenaline immediately after the impact... and was obviously hopping around like nothing was wrong... but I have to imagine smacking through a windshield like that had to lead to some internal bleeding/injuries that might not immediately seem apparent. According to a news story I googled, the driver stopped the bus, opened the door and the deer ran off... hopefully not to slowly die of with shattered ribs and bleeding organs and such.
