The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
The other criteria would evolve to match what the females like. The feathers would stop evolving to the color that increased mating and would get adapted to sth else such as having camouflage(the color of their ecosystem to stay hidden from predators).
Animalia.
