The Swan River is recognised as a very important area for waterbirds. There are 84 recorded species, of which 35 are seen regularly. But there has been a loss of species and abundance especially in the last few decades inparticularly caused by disturbance.
Disturbance can be caused by any human activity that alters the behaviour of birds. In 2003 a study on the river showed disturbance events were caused by everything from jet skis to people innocently walking along the shore.
When birds are disturbed they take off and fly away. This can become a problem as eggs and chicks can be left alone and open to predation and some beach-nesting birds are exhasuted after travelling so far and need to feed daily.
