Oh, yes; a female sparrow Hawk (I think) who has taken three wood pigeons from our lower garden and who thinks nothing of attacking a solitary bird right next to our lounge window. It's quite a sight, watching the predator seize the hapless wood pigeon in flight, then crash into the lounge window and start to dismember the only partly-dead bird on the balcony.
It's only this year I've realised they attack the larger birds, such as wood pigeons. Leave a right mess, too, after they've plucked the pigeon.
I'm guessing she's the same one, since they have a fairly wide territory, I believe. Feel a bit sorry for the wood pigeons but we have three bird stations and it must be like a smorgasbord for the Hawk :-) Magnificent to watch hunting, though.
