natural selection
reproductive maturity
genetic variation
genetic drift

The correct option is C) genetic variation

Explanation:

Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.

As the birds show different variations hence the term that best described them is genetic variation.
