Silver Gull

In a recent report on ABC News it has been found that Silver Gulls are becoming overweight. Over the last two years University of Tasmania researcher Heidi Auman has been studying Silver Gulls in Hobart and on the Bass Strait islands. She has found that the city birds have a higher cholesterol as well as being overweight when compared to their island dwelling counterparts.

Poorer Breeding results

In addition to being fatter, the city dwellers are laying more eggs but there are less chicks surviving. The main reason for their unhealthy state is a poorer diet. The gulls are not getting the correct food as they scavenge rubbish tips – and get fed by people having picnics.
