An island population of several different bird species is competing for the same resources of seeds and insects. What is the concept that best describes the splitting of this similar niche so that all species may coexist with these limited resources?

The concept of Niche differentiation or niche partitioning best describes the splitting of this similar niche so that all species may coexist with these limited resources.

Explanation:

The concept of niche differentiation describes that if there is a competition for a resource which is limited in the ecosystem, then the species thriving there can occupy different place, choose to eat different foods etc. i. e. differentiating their niche. In this way the competition among them decreases and they can coexist peacefully with limited resources.
