Answer:
Both bird species cannot occupy the same niche and, therefore, one species will die off.
Step-by-step explanation:
Introducing a new species of bird will lead to competition among the organism. The food source will not be adequate for both species and competition will set in leading to survival of the fittest.
The population that best compete will most likely to chase away the other species who do not have food because hunger and starvation will lead to death of the other species and the species that is able to find food will survive and reproduce and remain in the niche.
