Well done, Jill.

It must be very satisfying to see such positive results from all your
hard work!

Congratulations.

Colin

> Council responded to the report by limiting public access to one sand 
> island in the estuary from September until March annually, so that local 
> shorebirds can breed undisturbed. This is also helpful to migratory 
> birds. Vehicle access is now also barred completely to the northern 
> sandspit where up to 20 4WDs would park at peak times. Vehicles are now 
> obliged to park further up the beach behind the bollards and people must 
> now walk in, and leave their dogs, horses and camels with the cars. 
> Boats may still land on the sandspit.

> We surveyed last Wednesday, December 19. We found at least an estimated 
> 2740 migratory terns, made up of White-winged Blacks (WWTE), Littles 
> (LITE)and Commons (COTE). The vast majority were WWTE and COTE, and

> separate them to species level, when they came in too quickly it's too 
> hard. And the migratory terns arrived later this year than in previous 
> years.

> Also of interest was the presence, for the first time during our 
> surveys, of 2 Beach Stone-Curlew. If anyone has any records of this 
> species in Noosa before, I'd love to hear from you, just out of 
> interest. It's perfect habitat, but we hadn't seen them there.

> Of further interest was that I noticed two juvenile Bar-tailed Godwits
