Like many other bird species, Robins (Erithacus rubecula) need all the luck they can muster when raising a successful brood. What they don't need is someone or something near their nests. Again, when birds emit distraction calls or produce distraction displays, it often means a nest of young or fledged young is nearby. Learn the calls (in this case, the young themselves are calling), and you will quickly learn what bird is present.
