The feral pigeon is descended from the rock dove. Due to the favorable conditions of the habitat "city" - a relatively mild climate, plenty of food through the garbage of prosperity and feeding, absence of natural enemies such as Goshawk, peregrine falcon, unnaturally long winter days and advertising light - there is a large increase in the feral pigeon in cities.
According to a study of biologists from the University of Basel every feral pigeon produces about twelve kilos of droppings per year, resulting in odor and aesthetic impairments. Pigeon droppings decompose stones and concrete; and can contain more than 100 pathogens, but most are harmless to humans. The pigeons defecate preferred at their resting and breeding places - that fact uses the "Ausgburger Modell".
In supervised pigeon houses the pigeons can
specifically located, directly controlled and their population can be regulated. If these houses meet all ideal conditions, the pigeons from the surrounding areas are going there. In addition, previous nesting sites will made
inaccessible. Accompanying the food supply is reduced, feeding zones remain for human-pigeon interaction.
Projects in Basel, Tübingen and Berlin show that in this way
the pigeon problem can be sustainable, environmentally and animal friendly addressed. In addition, the building destruction is reduced and the pigeons stock can be reduced in a few years by a third. The goal
should not be the extermination of the pigeons, but a small stock
of healthy pigeons, because pigeons belong to the biodiversity
of our settlements.
