This post is a bit of a cheat, showing captive birds at a little butterfly and wildlife park that Lisa and I visited a couple of weeks back. I am quite pleased with the results though.
The Eagle Owl is a massive bird, a fully grown adult female is capable of taking a roe deer, although this one was quite happy tucking into a chick! They have recently started being seen in the wild in Britain, escapees from collections, with individuals being seen in Yorkshire, although I am not sure whether they are breeding or not. There are feelings that this bird can harm the native wildlife, out-competing other birds of prey and thus removing these from our landscape, I am not sure what to think of this, do we remove them, or do we live and let live?
The Burrowing Owl is from the U.S. and is similar to 'our' Little Owl, which is itself an introduced species. There is a whole can of worms to be opened when we start to look at 'true' native birds and ones that are not really, but have been in the country for so long that they have become thought of as native.
