Our story on Twit Twooo the owl has prompted comments on our Facebook page.
Martin Veart says: "Is it delivering a letter from Hogwarts?"
Michael Jones says:"My old friend is back on the bridge. I called it Hooter ... Being homeless you see more than anyone ... and if you hold your hand out with meal worms you can feed him. Seeing this has made my day, thanks ITV London. PS: He loves mice as well, his mum is around as well"
An ITV London viewer is appealing for the owner of an owl to come forward, after it landed on her head as she walked near Blackfriars Bridge.
Andrea Boatswain said the barn owl was tagged, and believes it is owned by someone who lives nearby.
She emailed us to say: "He was last seen on roof of building works in Marigold Alley, SE1 opposite the flats. I walked him on my head around there. Blackfriars Bridge just past the pub at side of bridge facing the river. He may belong to someone living in those flats. He was tagged. Very friendly."
