How can the extinction of bird species create a ripple effect through the rest of the ecosystem?

Birds control rodent and insect populations. In the absence of birds, the integrity of plant communities would be degraded. This would in turn affect the other animal species that depend upon those plants for cover and food. Birds are important pollinators for many plant species and are a crucial agent in seed dispersal. Birds provide critical natural services that other species depend upon.
