Without the bird in the habitat, a whole habitat can "shrink."  The birds allow for pollination by spreading seeds.

Invasive species can affect native bird biodiversity. If the invasive species is a predator, the bird population would most likely decrease.

Birds...are important for pollination, spreading seeds around the forest and controlling insects that feed on plants...Before introduction of the brown tree snake, Guam had 12 species of native forest birds. Today 10 of those are extinct on Guam, and the other two species have fewer than 200 individuals. http://www.washington.edu/news/2008/08/21/brown-tree-snake-could-mean-guam-will-lose-more-than-its-birds-2/
