Lovely shot. I can see why you want to remove the yellow over the owl, but its still a great shot with it.
I have still to get any decent bird of prey shots. I realise that baiting is the way to go, but unfortunately haven't had the time or place to set anything up. Have you got any tips as to how to lure them in? Ie which birds like what sort of bait, what time to bait etc? I might have a go trying to set something up in the field out back.
We've yet to succeed with any pictures, but so far all the rabbits and pigeons have been totally shredded by birds of prey, at this stage we're more concerned with keeping tracks on "what gets eaten where" than photography..
In terms of tips for luring them in, the scavengers such as buzzards will come down on anything. (they can pick a rabbit out from 2 miles away with their eyesight) if you're in a particularly gruesome mood, to get instant attention pluck the rabbits fur and spread the white hair all over the place, this tells the eye in the sky that the carcass has already been partially opened up - even easier meal.
Don't worry if you get loads of magpies/crows turning up first, as this is like a giant McDonalds sign appearing over the baiting area.
My friend has done a lot of sparrowhawk photography using dead pigeons propped up in lifelike positions, sparrowhawks will not often scavenge from a carcass but they can be fooled quite easily by presenting a pigeon in this way, they'll strike the dead pigeon and then stand there pinning it to the ground looking all proud as though they've just killed something

Use tons of camo, we'll be parking up near the bait and totally covering the vehicle in scrim netting, 100% camo, lens covers and balaclavas, silent mode mirror lockup shooting only - sports mode doesn't go down too well, as I discovered with owls!
It'll be worth it when it happens and the shots are truely yours.. I don't mind captive bird photography but its too controlled for me, I love the character and untamed madness of some birds that you only ever see in the wild, I get quite a buzz when something comes along allows you to take a picture then flies off never to be seen again. For me its all about capturing the moment.
