Great Crested Grebe

this is one for all you twitchers ( hope I spelt that correct) out there, I snapped this little mother and here chicks on the way home from work this morning on hogganfeild loch, I am not sure if they are out of there breeding area because when I looked up my bird book ther area seemed to stop around the scottish border area , it would be nice to know if I have found a stray from the normal breeding area .
