Intermediate Egret (Ardea intermedia, Lake Joondalup, Western Australia).  Photograph has been cropped.

After attempting (and failing) to twitch the White Wagtail at Lake Gwelup, Alan Collins and myself checked out Lake Joondalup for the Intermediate Egret that was reported there.  We found the bird relatively easily as it moved about on a large patch of weed/grass.  This takes my life list to 257!  Interestingly, in the last fortnight or so I have doubled the number of egret species I have seen (*).

* I had actually seen three egrets prior to adding the Cattle Egret and Intermediate Egret (I had forgotten about the Eastern Reef Egret).  Thanks Alan!
