        Pisonia Forests and Noddy Terns | Life on the Reef

        Learn about symbiotic relationships from scientists who studied bird numbers in the Capricorn Cays, in this clip from Life on the Reef. The islands of the Capricornia Cays have supported large pisonia forests where the sea birds breed and nest. However, the sticky seeds from the Pisonia trees stick to the seabirds and have hindered them from flying. This has caused many seabirds to die and enrich the soil for Pisonia Trees to grow. Watch the scientists explain how this symbosios has effected the island ecosystem.
