Question

How would an increase in nest sites affect a population of pigeons? The population would decrease. The population would increase. The population would remain almost the same. The population would be reduced the next year.

Answer 1

The population would increase

Answer 2

It's actually a tricky question.

If we consider a year or two(comparatively lesser time) the population will remain almost same(very slow increase will happen), due to the limiting pressure in single generation. But in broad aspect or over time if the increased nest sites remain constant the population of pigeons will definitely increase.
