LSL day 37. Saw the fledgling currawong for the first time today. Heard him for at least a week. Mum has been aggressive for at least 6 weeks. Attacking the lorikeets and chasing them from the balcony. No other birds dare approach the balcony now. When she started chasing them away from the kitchen window. We had to train her - no more feeding her there. She flew close but didn't swoop.
