If you take away a species’ natural habitats it will be forced into using man-made ones. Urbanisation often pays off with increased foraging opportunities and shelter. The peregrine falcon's increased utilisation of urban areas seems to be another good example of species thriving in urban areas in the UK. Other classic examples include foxes, hedgehogs, seagulls and red kites.
A BTO survey in 2002 showed peregrines lived at 62 man-made structures including those in urban areas. This was an increase of 48 peregrine territories on human sites since a census in 1991. Results are not yet out for the latest survey undertaken in 2014, however there are increasing anecdotal reports of urban peregrines, with the birds now found in most of the UK’s cities.
