For the past eight years, a pair of peregrine falcons have nested on a suburban Perth balcony, high above ground level, and successfully raised seven clutches of chicks. Some people in the building were not happy with the mess and noise that came with baby birds being raised in their neighbourhood, so sought to deter the birds from returning this year. But it appears the birds have no plans of leaving.
"Now there aren't any cliffs in urban areas, but there are buildings with window ledges which often resemble cliffs," she said. Most of the pictures of the so-called Crawley Falcons appear to be taken from behind a glass balcony door, which makes sense given the predatory raptors have sharp talons and can be protective of their young. The birds, which can swoop at speeds of more than 300km/h, are also protected, so are not to be disturbed by humans.
