'Dirk Hartog' and his wife started turning up regularly about two weeks ago, after a roughly two-three month absence during breeding season. Very exciting today because a beautiful baby boy was in tow(!).
Feeding by himself in the tree with Mrs Hartog dozing and watching on.
None of 'my' nests belonged to Dirk, so he was either one of our other known nests, or he still has a mystery nest for us to discover(!)
