As part of a small project I have I count sometimes at a point on Mt Majura birds passing by in the afternoon on their way to a roost, this includes Crimson Rosellas. This afternoon (30 Jan.) out of a total of 102 birds only 7 were young, i.e. about 7% of the birds. Although in the past I have not separated birds by age class, just from general impressions, the count tonight would indicate very poor breeding success. Most birds passed as pairs or groups of adults only, very few family parties were seen.
 
This is matched by  day observations in the suburb of Ainslie, on Mt Ainslie and a few other areas I visit: there are some young around, but far fewer than in a "normal" year.
 
Clearly the drought is biting and even species we may not consider to be too much affected, definitely are.
