I was surprised by this forum's apparent lack of interest in the
recent alarming UNSW research finding that shorebird numbers (both of
resident and migratory species) have declined by 75% over the last 25
years.

Should we accept this gloomy picture or was the surveying perhaps
inadequate to be able to make such a bold statement? Certainly,
recent summer wader numbers are much lower at sites around Perth, eg
Alfred Cove and Rottnest Island than they used to be & this is
confirmed by Birds Australia counts. Has a decline been noted at
well-documented wader hotspots such as Roebuck Bay and Cairns
Esplanade?
