A robin sang all day, first on the highest branches of the just budding horse chestnut tree, then closer to the cliff on the highest branch of a hazel. I have never heard such lovely singing. He would win prizes, if there were any. He sang against a blue sky, one of the first of this cold spring. I hope he finds a mate, if he was singing for one. I did hear an answering song, a long way off. But maybe he was warning his neighbour to stay away from his territory, after all, I am supplying him with mealworms, sunflower seeds and fatballs.
