Today in our environmental science lecture, we're discussing urban wildlife. One surprising example is the peregrine falcon, which has adapted to city life. Unlike their rural counterparts, city falcons nest on tall buildings instead of cliffs. They feed mainly on pigeons, which are abundant in urban areas. Interestingly, studies show that city falcons have a higher breeding success rate than those in the countryside, largely due to the warmer microclimate of cities and the constant food supply. However, they face unique threats, such as collisions with glass windows and exposure to rodenticides. Conservation efforts now focus on installing nesting boxes on skyscrapers and encouraging building designs that are bird-friendly.
❓ According to the lecture, why do peregrine falcons in cities have a higher breeding success rate?
A. A. Because they have fewer natural predators
B. B. Because of the warmer climate and steady food availability
C. C. Because they nest on cliffs which are safer
D. D. Because they receive help from conservationists
✅ 正确答案
B. Because of the warmer climate and steady food availability
