Hi Lindell

We (Red hill Regenerators and members of COG) have been watching Gang-gangs for seven years now - our original interest was in stopping a development that included a nest tree.

In the Wild Gang-gangs incubate for 4 weeks with chicks taking 7-8 weeks to develop.

Where we have observed mating it is usually quite close (ie tens of metres) from a nest but we are unsure if that is because we spend a lot of time looking at nesting hollows or whether mating is indicative of a nest nearby. If you could keep an eye out for Gang-gangs entering a hollow usually around 15cm wide 22cm high that would be great. So far this year we have identified 19 nests in the Canberra area (and around 60 overall) and about another six elsewhere over the Gang-gangs range. We are currently monitoring Gang-gang breeding success - just lost two chicks when the limb in which their hollow was in fell to the ground last night- which is pretty sad.

The chicks in one of the Canberra nests are well advanced and will probably fledge around Christmas. The eggs in about 11 nests have recently hatched sp we are looking at a late January fledging and then there is a third group to which your mating pair may belong who are only now getting down to egglaying with fledging late February early March. They will have already found their hollow and lined it with about a cm of bite sized bark chunks. Despite the large variation in fledging date within  the same general location there does seem to be a significant relationship between fledging time and altitude with the lower the altitude the earlier the fledging. 

If you can put images of any Gang-gang mating or hollow activity on Canberra nature Map it helps us understand what is happening around Canberra

Thank you to all who responded to my email and Ian, for the details on what may happen now. I'll look forward to mid-February.

Lindell, she will lay the fertilised egg in the morning, and quite likely another one in a couple of days. It will hatch in around 25 days, then the chick should fledge in about 6 weeks. However it seems that most of our information is from captive birds. So, perhaps you could prepare a welcome for about mid-February?

6.30am I opened the Family room curtains today and this was my early morning greeting.

These two are regular visitors to our garden. They call in most days in search of seed that I may or may not put out for them and their other parrot friends. After seeing this my question is - how long need I wait for these two to introduce their newly fledged offspring? That is supposing they find a suitable nesting hollow and are successful at rearing their chicks.
The closest nesting hollows that I know of are up on Red Hill.
