Why do Peregrine falcons nest on buildings?
Peregrines typically nest on ledges of rock cliffs. However, falcons have been able to adapt to use tall buildings. If you think about it, a city skyscraper is tall and constructed of concrete or stone, just like a rock cliff. Window boxes and other niches on buildings provide a place for a female to lay eggs. Man-made nest boxes and trays lined with pea gravel are also used by falcons. What kind of nest do peregrine falcons make? Peregrine falcons do not bring nesting material to an area to build a nest. Instead, they make what is called a scrape or shallow depression in existing gravel or other debris by lying down and pushing back with a foot. Why doesn’t Amelia sit on her eggs all of the time?

Once incubation begins, one of the adult falcons is usually sitting on the nest, however during warm weather or food exchanges
