Dog walkers are being urged to keep their dogs on a lead as chicks begin to hatch around the Marine Lake.
Ducks,Geese and Swans are all looking after their young at the moment.
A spokesperson for Southport Swan Rescue said,
'Unfortunately there has been an increase in recent years of some owners letting their dogs swim in the lake. This has led to wildlife being chased and in one recent incident a duck was killed by a dog'.
