Corvid Cleaning, a Swedish startup specializing in training crows to pick up litter in exchange for food, claims that its program could save communities a fortune in cleaning costs.
According to the Keep Sweden Tidy Foundation, over a billion cigarette butts are left on Sweden’s streets every year which represents about 62 percent of all litter. Teaching humans not to throw cigarette butts on the street has so far proven impossible, but a Swedish startup claims it can teach crows to pick up after us and save local communities millions of krone in cleaning fees every year. Corvid Cleaning teaches wild crows to do our dirty work through a step-by-step learning process, that involves rewarding the birds with food for every cigarette butt they collect.
