Final answer:
Peregrine falcon reintroductions in cities have been successful mainly due to an A)abundance of prey, cliff-like structures for nesting, and lack of competitors for food and nesting sites.
Step-by-step explanation:
Peregrine falcon reintroductions in cities have been successful for several reasons, but when evaluating the options provided: A) Abundance of prey, B) Urban habitat mimics cliffs, C) Lack of competitors, and D) High reproductive rate, two factors stand out. Firstly, cities offer an abundance of prey such as pigeons and other small birds, which supports the falcon's diet. Secondly, the urban environment's tall buildings provide a cliff-like substitute that suits their nesting preferences. Lack of competitors in cities for nesting sites and food also helps peregrine falcons to thrive in these areas. While a high reproductive rate may contribute to their success, it's primarily the ample food supply, suitable nesting locations, and reduced competition that are key factors for the falcon's urban success.
