one time I left the screen door open and a bird flew in. so we tried to get it back outside but instead of going back to where it came from it ran into the big window in my house and dropped to the ground. we cared for it for 3 or 4 days and then I woke up and was wondering where the bird went and my dad had let it free because it was healthy enough to go home. i never saw that bird again, but maybe it's for the better.
