Went to check yesterday's site of female fledgling on way to hollow at about 8.45 am. She wasn't there but heard calling from different direction and found male chick with parents about 112 m from hollow. All three then flew to another tree about 100 m away (2nd and 3rd images). The parents then flew another short distance to the female chick (4th image) and all three indulged in a tangle of mutual grooming. They then flew back to the male chick (last image) at which stage I left.
