Lonesome Dove
He hangs around the usual places (except for the nest), hoo-hoo-ing hopefully (he's up on across-the-street's TV aerial at the moment, watching me type this). But it looks like she's gone, and for whatever reason, she isn't coming back.
Earlier today, a sparrow was checking out the nest over next-door's halogen light. (I guess that's what you call an opportune-nest [ducks]). Ironically, the house has just been re-let - the previous tenants moved out last week.
FWIW, here's the last photo I have of the two of them together.
