Bird of prey

Whilst visiting Prague Castle, there were these captive birds of prey. I really don't know which one is which and even though I would prefer to see them in the wild rather than tethered, it was a good opportunity to capture some images. Can anyone identify them for my 'edification'?

Never seen one of these before, lovely striped chest. I think it might be a black and white owl, but could be wrong

@yorkshirekiwi I uploaded another photo of the same bird which looks a lot less contrasty - it is much more brown than it looked in the first photo??

What a fabulous shot Liana. I'm afraid I'm no use to you for identification purposes. We've seen a few of these tethered owls in various places too. Some of them were being used to raise money to care for orphaned owls. They were all just bewitching. Isn't Prague just wonderful - one of my favourite cities.
