Mason Park waders. Do they "migrate" with tidalmovement?

["Tom and Mandy Wilson" <>]

The waders at Mason Park often feed in the 2 drainage channels next to the 
wetland when the tide is out, which meet to make the mangrove lined channel 
of Powells Creek, which flows into Homebush Bay.  Of course, some of the 
waders may disperse elsewhere as well.  However, at low tide I have also 
seen waders loafing at the wetland itself, so in my experience they don't 
all disperse.
