This pair already have two hatchlings and the female is brooding them. The female changes her position from time to time. The male was away for hunting and has just brought back a small bird (an unidentified species). As the male arrives, the female leaves the brooding position and receives the small bird from the male. She tears up the bird into pieces and gives them to the hatchlings.
This pair nested on a terrace roof on the 17th floor of a building in Kanazawa City. In the year 2000, when they first nested, they failed to raise any fledgling because the eggs rolled around over the roof. Next year, with cooperation of the building community, we put a gravel layer over the roof (gravel size 6-9 mm). The falcon pair successfully reared three fledglings, which is the first case in Japan that the peregrine falcons successfully fledged young in cities with many high buildings. The pair fledged young in 2002 and 2003 as well. Human assistance in establishment of favorable nesting environments appears crucial in successful reproduction of the peregrine falcons in urban environments. ¡Êtranslated by Asoh¡Ë
