All those alleged fairy wrens that look like Variegated Wrens. See entry above under Blue Winged parrot. I've torn these pages out too - useless lumber. Don't make me laugh. Days spent at Werribee Sewage Farm confirm that these are merely another single variable species, best subsumed under Sharp Tailed Sandpipers.
People probably hallucinate from the fumes.
Last time I was there some 'expert' pointed out a large and boisterous Sharp-tailed Sandpiper and called it a Rough. My revised guide has only one page for waders with several illustrations showing some of the major but still trivial local variations in plumage, size etc of Sharp Tails. This is, of course only a start. I was pleased to see an honest emailer point out recently that the Lewins Rail is 'probably extinct nowadays'. Of course it is.
