In an ecosystem when a large number of species are dependent on one particular species of bird this makes the bird a keystone species. This bird has a disproportionate effect on the surround environment because so many others are dependent on it.

Keystone species
The species of bird that other species are dependent on is called a keystone species. Keystone species have a disproportionately large impact on their ecosystem relative to their abundance. This particular bird species plays a crucial role in maintaining the balance and health of the ecosystem.
This is a "keystone" species.
A large number of species are usually dependent on the Keystone species. The Keystone species usually regulates the abundance of the other species.
Biodiversity is the measure of the number of species living within an ecosystem.
species diversity is the number of species that live in one area (or ecosystem)
by the number of species it contains
by the number of species it contains
There are several ways to measure biodiversity in an ecosystem, including species richness (the number of different species present), species evenness (how evenly distributed the species are), and species abundance (the number of individuals of each species). Other methods include genetic diversity (variety of genes within a population) and ecosystem diversity (variety of habitats within an ecosystem).
