As far as I know, Ravens and Hooded Crows don't interbreed, nor is that likely to be albinism. Instead, it looks like a Pied Crow which is in fact an African species not indigenous to Europe at all. As the bird has rings and might even have clipped wings it could be some 'pet' which is thoroughly irresponsible. Ravens and Crows can be tamed to an extent but their foul and insanitary instincts cannot.....If this touched woman is 'bringing' Ravens to the castle from time to time then their wings must be clipped or else they would fly to their hearts' content. The Pied Crow may be one of these unfortunates too, these are not pets and should not be kept in this grotesque manner to gratify the ego of owners. Ravens frequently fly over my house en route to the forest with their distinctive coughing croak, large formidable birds with great intelligence but they are aloof & distant by nature. People turning them into some kitsch gothic tourist feature is intolerable in my view.
Sorry for the OT aside but environmental issues mean a lot to me. Watch out for the shiny bolsters of your knives...Crow family are attracted to glittery things and may cache them
