Date: 01/01/2000 Number: 69,000 Counter: 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. |
