Text: The count of flying-foxes increased to an estimated 80000 over January 2000. All flying-foxes exiting the colony (except for 200 to 300) appeared to fly north. Red bloodwoods (Corymbia gummifera) were reported to be flowering profusely north up to the Hawkesbury River. The increased counts during January 2000 would probably be due to bats visiting in response to this flowering. Also juveniles (this season's young) began to fly from the Gordon site.

Text: Through late March into April there has been a large drop in numbers. This has been attributed to the response of flying-foxes to the flowering of Spotted Gum stands near Bateman's Bay and Bloodwood stands along the Colo River and at Mallacoota. The Cabramatta Creek Colony and the colony at the Royal Botanic Gardens Sydney have also had similar low counts.

Although they were not flying with great speed they did fly with great purpose. Most flying over the Bridge headed in a NW direction with low numbers breaking away from main steam about 3/4 of the way into the fly-out.
