Hi . They might have just left the nest as its that time of the year when they Fledge
I live in a townhouse and there are four house connected together and a lot of other townhouses beside of me and the 1 owl was on my roof and 1 owl was on my neighbors roof talking to each other it sounds very weird and then like a year later I see one on my roof and I don't know if the other one was around on somebody else's roof r not and I just didn't see it i only seen the one but this time it wasn't saying nothing and I went up stairs to get my phone so I could take a picture of it and I did but no sooner I got the picture it flew away does this mean anything
