The busy Sorell causeway in Southern Tasmania is proving to be a death trap for the region’s silver gull population, with large numbers of birds being struck by traffic.
This narrow stretch of the Tasman highway is a significant gully colony, where about 300 nests have been established and 700 eggs laid this season.
Eric Wohler from BirdLife Tasmania said there had been a slow increase in the number of birds at the colony since egg oiling ceased in 2018.
