I think that might be Ivy birnut. Ivy was sitting on the nestbox until just before nine am and then he took off north around the Radisson. At the moment Joli is sitting on the Roger's sign looking north. They can't see each other if they are still sitting on their respective signs if I recall correctly, but they both can see the nestbox and the roof of the Radisson if Princess or a foreign interloper should turn up ... maybe they know that snow is on the way?
