Lonely creatures on this lonely Planet .

So intolerable is loneliness that even animals attach themselves to any creature they can scrape an acquaintance with. There is a case of a pony confined by itself to a field, and a solitary partridge, the only one of its species in that place; they were always seen together in close companionship. Then again there was this lonely Swan, driven away from its group, who eventually made friends with a trout. The fish had its place by the side of the bird, just below the surface and together they would rest and together they would travel like one being…. Those who saw it could not believe their own eyes or senses. - Adventures among Birds.-
