The number of town pigeons in Berlin is estimated to have fallen to 10,000 from 30,000 in 2001 according to a report from the nature protection association Nabu, one of largest in Germany.
Part of the reason appears is that there are fewer nesting places now that wires, nets and metal spikes have been installed on new buildings. Another reason may be the ban on feeding pigeons.
At the same time there has been an increase in the number of hawks, crows and wood pigeons in the capital, as they migrate from an increasingly hostile countryside to make the most of the green areas in the city.
