Answer:
extinct.
Explanation:
The yellow beetles will become extinct because they will be under the continuous pressure of being eaten by the birds. According to the theory of natural selection, only fittest species survive (Survival of Fittest). Hence, Green beetles would take advantage of having similar color and avoid their preys whereas yellow beetles will stay prominent and would be the regular food of birds. Initially, their abundance will be lowered and later on, they will become extinct.
