Crow raises the bar

It was fascinating to read in the New York Times on 19 August about crows are being trained to clean up the park in France. The crows are trained to pick up cigarette buds from the park and dash it in the bin. The trainer has six crows which are brought in a box to the park and sent to clean up the park and as a reward, they are given a piece of cheese. This might look like animal abuse or work but crows like to play. The trainer opined that it is a play for the crows and in fact they enjoy doing it. He also says that it is to make people guilty that they should clean the park, not the crows. 

While this fascinated me, I wondered how animals can be taught to do something good like this and they do it faithfully. Of course, crows are considered to be intelligent birds. Do you think they are more intelligent than humans? Then why humans don't clean up but mess up the park? Humans also need to be taught even though humans are intelligent beings. What is taught to humans is important but soon taken for granted or can be influenced by other factors such as this, not our park or I didn't dirty the park and so on?

Animals also have a degree of belonging to nature hence they can feel with nature. If they feel nature is not suitable or habitable they migrate to a better habitable place in nature. They are close to nature than humans. It is important that humans take some cues from animals so that our nature is protected and kept clean. In fact, humans need nature more than animals because most animals can migrate from one place to the other without much difficulty. But humans cannot migrate so easily for there are more constraints of migrating.
