Ok , I have in the last several years, gotten closer to robins, than any other time in my life. Both times was when Im using my metal detector in the early spring. Do you think the activity stirs up the worms or something in the penetrating electronics stirs them up or draws the birds. Anyone else ever experience this? I can get probably 4 feet away and they just dont take off, Just keep going about their business. One thing Ill say is both times it was after Id been there swinging for several hours- do you think they watch from afar and figure im just no threat so they encroach cautiously towards me? CO
