Innovative Efforts to Train Crows to Collect Cigarette Butts

environment · Sweden and the Netherlands

Start-up companies in Sweden and the Netherlands have piloted projects to train wild crows to collect cigarette butts in exchange for food rewards, aiming to reduce litter. However, concerns about the impact on birds and funding issues have challenged these initiatives.

This is the archive, not the newspaper. Between 2018 and 2026 this site compiled these items automatically from public community sources — chiefly The Islands Grapevine, regional news feeds and community groups. They were not written by a reporter and were not held to the standards this publication now applies. The archive is kept because it is a useful dated record of what happened on Denman, and it is labelled because pretending otherwise would be the first thing we would tell you not to trust. Current reporting is at The Denman Firestarter.
