Dutch Startup Using Crows To Clean Cigarette Litter

It’s more than likely that we call groups of ravens an unkindness due to their unforgiving intelligence. A Swedish experiment training birds to earn food rewards had one raven hacking the project entirely. The thoughtful budgie even took the time to teach other birds the secret. Now, startup Crowded Cities is testing the brainpower of crows, using them to pick up litter.

The idea is to train the crows to drop cigarette butts in a ‘Crowbar,’ which scans the item to confirm it’s a cigarette butt, and then gives the crow a food reward to reinforce the behavior.

Considering the amount of cigarette butts that end up on sidewalks annually (about 4.5 trillion), these crows could make a difference. The butts are not only non-biodegradable, but toxic to marine life. For ultimate efficiency, the Crowbar uses a simple give-and-take mechanism.

[Everything] is done with the intention that the crow will fly away and inform others of this system, so that more crows participate in cigarette butt collecting.

Research has found that crows are as cognitive as apes, so the success of the Crowbar should be anticipated.
