How would an increase in nest sites affect a population of pigeons?

An increase in nest sites would likely lead to a rise in the pigeon population, as more available sites would facilitate breeding and reduce competition for nesting locations. This could result in higher survival rates for chicks, ultimately increasing overall reproductive success. Additionally, with more nesting options, the population might also expand into previously unoccupied areas, potentially affecting local ecosystems and food resources. However, if the increase in nest sites exceeds the availability of food or other essential resources, it could lead to overpopulation and subsequent resource depletion.
