Across the European alpine regions in summer, cattle and other farm animals feed on alpine pastures high up in the mountains to fatten up on the rich alpine grasses before the colder months.  When the cattle are herded back down to the valley at the end of summer, locals (and holidaymakers alike) celebrate the herd's safe homecoming by dressing the animals up in ornate headdresses, garlands of flowers and ribbons, and with bells attached to heavy leather collars.
