Robins: heroes or villains?


                                                                                                           Finding a mate

                                                                                                           around March, though this can be earlier
                                                                                                           if it’s been a mild winter. Both male and

              In the winter, the male will oƒen

              drive out the female and offspring

              from his territory. Some robins
              stay in the UK all year round, but
              others migrate for the winter.
              Setting up home
              The female takes responsibility for
              building the nest, typically in nooks
              and crannies near the ground, such
              as tree roots, hedges and walls.
              The nest is mostly comprised of
              leaves, moss and hair.

              female, meanwhile,
              starts preparing a nest
              for a second brood.
                                           Laying eggs
                                           A normal clutch consists of four to six
                                           eggs, one laid each day. They are pale                     Molt

              Split personality
              When it comes to behaviour, robins really are the Jekyll
              and Hyde of British birds. Around humans, they are some
              of the most sociable and inquisitive birds to visit our
              gardens, often venturing surprisingly close to pick up bugs
              from freshly turned earth. They are attentive partners
              and hard-working parents, rearing as many as four or five

              clutches of chicks over a season.
                But when it comes to rival robins, these sweet birds
              see red. Throughout the year, what we hear as cheerful
              chirping is, in fact, a curt message telling others, in no
              uncertain terms, to keep away. If this is ignored, robins will
              find a prominent perch, lift their head and present their


              bright plumage as a final warning; usually at this point,
              one will defer to the other. If singing and posturing doesn’t
              scare off the competitor, robins revert to violence. Flying
              at their adversary, they will peck and scratch with their
              talons until one concedes defeat or, in extreme cases, is
              killed – often by the severing of the spinal cord. Indeed, an
              estimated 10 per cent of adult robin deaths are committed
              by members of their own species.
