rfi - breeding Silver Gulls in south-eastern Australia

["Peter Menkhorst" <>]

Mud Islands in Port Phillip, Victoria support one of the largest Silver Gull 
breeding colonies - estimated at up to 50 000 pairs continuously between July 
and January. However, this year there has been almost no breeding and I have no 
idea why that would be so. Does anybody know whether large numbers of Silver 
Gulls are breeding elsewhere in south-eastern Australia this year, perhaps 
where breeding does not normally take place? 
thanks
