THE NETHERLANDS (WIVB) — A Dutch start-up called Crowded Cities hopes to teach crows to pick up cigarette butts.
The birds are known to be highly intelligent, even able to make their own tools.
The “crow-bar” device includes a large funnel for the butts, along with a food dispenser.
A four-step process would reward the birds with food for each butt dropped in the funnel.
The company is developing a prototype before researchers study how the cigarette butts affect the birds.
