According to the Singapore Straights times...
"In Sydney, an abandoned baby humpback whale has apparently mistaken a moored yacht for its mother.
'The calf has spent the last day or so in Pittwater and we believe it has been nuzzling up to a moored vessel in an attempt to find milk,' Mr Chris McIntosh, local manager for the New South Wales state national parks service, said yesterday.
Experts say the baby whale cannot survive more than a few days without milk provided by its mother.
Rescuers tried to wing the yacht out to sea, in an attempt to lure the calf into deeper waters and away from Pittwater, which is north of Sydney Harbour."
