Scientists have discovered an amazing thing: why most picks are there mutilated paws, especially with regard to city pigeons. The fault is human and the answer must be sought in our hair. What does that mean? A French study conducted by a team from the National Museum of Natural History in Paris, led by Frédéric Jiguet, shed light on this observation.
Among the main causes of flyer leg problems are the human hair. The team closely observed the behavior of these animals, which usually roam the streets and congregate in the squares of large cities. However, the habit of visiting crowded places can cause several problems as human hair would tangle their paws.
Human hair, the main problem of pigeon leg injuries

Many pigeons exhibit Hair braided to the paws. In some cases, the hair would not only damage the birds’ fragile tissues, but would also not allow blood circulation. When the hair is too tight, it acts like a tourniquet and prevents blood circulation, which can cause the tissue to die and fingers to fall out.

The French research team surveyed nearly 50 areas of Paris, the places where pigeons congregate the most, and checked the number of mutilations. As can be easily understood, most of the mutilations were observed in populated areas and dirty. This means that there is a close relationship between human demographics and bird injuries. In short, albeit unintentionally, we harm poor animals.

The hair falls out and settles on the ground, on the streets, on the sidewalks and on the balconies of houses. The fingers of the birds, when at rest, intertwine in the hair, which forms a kind of knot that smothers the phalanges. The fingers of the animals, then, they go into necrosisuntil it falls. On the other hand, in green areas or in the countryside, the mutilations are much lower and this aspect has given the researchers the definitive answer.
