Last month, I wrote about some very interesting projects started by the Dutch<\/a>. I came across another one this month, that I would like to share with you: Crowded Cities.<\/p>\n

Sigarettenpeuken\u00a0<\/em>or cigarette butts are an issue in all major cities. In the Netherlands, 6 billion cigarette filters are thrown to the streets each year creating a problem for city officials. How can cities cope with this unbelievable amount of cigarette butts without it costing too much?<\/p>\n

The Dutch startup Crowded Cities<\/a> has a solution: crows.<\/p>\n

Crowded Cities<\/h3>\n

The founders of Crowded Cities have created The Crowbar that trains kraaien\u00a0<\/em>or\u00a0crows to pick up the butts. The crows deposit the cigarette butt in the container, and, once the container verifies that this is in a fact a cigarette butt, it gives the crow a little bit of food thus incentivizing the hard work of the crow.<\/p>\n

According the website Animals Today<\/a>:<\/p>\n

De kraai is een uiterst intelligente vogel. Ze staan bekend om hun probleemoplossende vaardigheden en geweldige communicatievaardigheden. Wanneer een kraai bijvoorbeeld een mens tegenkomt die het niet goed met ze voor heeft, leert hij andere kraaien hoe ze die persoon kunnen identificeren. Onderzoek heeft zelfs aangetoond dat een kraai een gezicht niet vergeet.<\/em><\/p>\n

Veel kraaien zijn op zichzelf, maar ze eten wel vaak in groepen. Een groep kraaien wordt een \u2018moord\u2019 genoemd. Als een kraai sterft, omringt de groep de overledene. Deze begrafenis is niet alleen om te rouwen om de dode, maar ze komen ook bij elkaar om uit te zoeken wat hun lid heeft gedood. Als het een roofdier is geweest, spant de groep samen om het dier te achtervolgen.<\/em><\/p><\/blockquote>\n

Downsides<\/h3>\n

While the project sounds very practical and helpful for cities, there are some obstacles. There is no study (yet) into the dangers for crows. Could the toxins from the filter harm the crow in the few moments this is in the crow’s beak? We know the side effects of smoking and second hand smoke in humans, but a study about these problems in animals exposed to the cigarette butts and the smoke has not been done.<\/p>\n

There is also the cost of buying and maintaining The Crowbar. How many of these devices would a city need to have and would a lot of maintenance be required to clean the Crowbar and add food to it.<\/p>\n

Some people might also be uncomfortable with the idea of an increase in crows flying around cities. There are superstitions related to crows about bad luck or even announcing death, not to mention people who are just plain scared of these birds. In Papendrecht, near Dordrecht, there was an incident of crows attacking people. The following video explains more.<\/p>\n
