Excellent work Michael, hopefully I can provide more than one sighting next 
season!!! Just curious, where do WTNT breed? I would have thought that the 
reason for their decline is most likely due to an issue such as hunting (as 
happens at edible-nest swiftlet colonies) or destruction of habitat, but I'm 
assuming that the reason for a decline of WTNT is unknown at this stage?

> The next record was of 50+ birds at Kuranda (QLD) on 12.8.2011 seen

> Island, near Cairns (QLD) on 2.10.2011.  Ron Becker saw the first  
> birds in Victoria when he estimated 40 birds at Genoa on 3.10.2011.   
> No more were reported in Vic until Kerrin & Rosemary Martin saw 15 at  
> Narbethong on 9.11.2011.  This is the first time for several years  
> when I have not seen any at Thurra River Rest area on Melbourne Cup

> Then a little surprise came when Kathy Wilk and Richard Baxter

> WTNT appeared to be late coming to Victoria but that did not stop

> that Michael Wood saw one on the Cocos Islands 4.12.2011.  A few  
> wanderers this year.
> 
> The first records I have for the ACT are of 3 birds seen by Alastair  
> Smith on 10.12.2011 and 2 birds seen by Steve Holliday on the same  
> day.  Steve made that record last year also.

> 217 from Qld, 327 from Vic,  & 714 from NSW.
> 
> This season the largest group seen was of 2,000 birds recorded by J.

> 
> 
> The average flock size this season was 40 compared to 44 for last
