hi there, i had a pigeon who walked in through my front door 2 days ago and has stayed. i thought these birds found there way home? it's a homing pigeon but he/she walked in and went in every room of the house and has stayed. i'm honered with it's company and my cat and dog are not bothered by it or the other way around. i'm just interested to know if someone here might know why it's done it?
