In some residential areas in Sweden, special machines have been put into trial with the goal of reducing urban waste using… the intelligence of crows. These devices operate on a simple principle: when a crow drops a small piece of trash, such as a bottle cap, scrap paper, or light metal, into a detection slot, the machine automatically releases a portion of food as a “reward.”
According to animal behavior researchers, crows are among the most intelligent birds, capable of learning patterns, remembering, and passing on experience to their peers. This characteristic helped them quickly understand the machine's “rules of the game”: trash equals food. After a short time, many crows actively searched for trash in the surrounding area to exchange for food.
These intelligent machines not only contribute to environmental cleanup but also open up a new approach to combining technology with the natural behavior of animals. Instead of relying solely on humans, the system leverages the birds' learning abilities to collect trash in hard-to-reach places such as under park benches, along sidewalks, and in densely populated residential areas.
Environmental experts consider this model highly innovative, but also emphasize the need for strict control to avoid altering the crows' natural survival habits. If implemented correctly, it could become an interesting supplementary solution for cities facing the problem of urban waste.
The project is still in the testing phase, but has already attracted significant international attention due to its unique idea: transforming "intelligent birds" into unexpected "garbage collectors" for modern cities.
