I would like to believe Sydney birdlife is not declining, but
word of mouth and my own experience suggest otherwise. Noisy
Miners moved into my area about 30 years ago and since then almost all
the small birds have disappeared. I have scarcely seen a small
honeyeater, pardalote or Fairy-wren in this time - even the Bul-buls
and sparrows have moved. (The Common Mynahs declined in numbers
but recently seemed to have increased again.) The only native
species which may have increased in this time are the Rainbow
Lorikeets , Crested Pigeons and Koels.
Whether or not "Sydney's Royal National Park has around 279 species" has absolutely nil bearing on the suggestion (which I strongly suspect is an urban myth, based on nil evidence) that our birdlife is on the decline in Australia's largest city. (No doubt some species have declined, others increased, others constantly change up and down.) Number of species that have been recorded in an area is irrevelant to an assessment of change to population levels of many species. Anyway, where are the long-term detailed population studies of Sydney's birds? No-one at my 28-4-2001 talk to SNAG in Sydney, about COG's GBS said anything like "we have something like this in Sydney"! --
