My position on Common Mynas is to support their demonisation, along with a number of other pests. However I am intrigued by Bruce's comment "Studies in Canberra Nature Parks in the 1990s have confirmed agressive displacement of native birds and mammals from nest hollows." I spend a fair amount of time in parts of Canberra Nature Park and the only place where I have really noted many mynas once out of sight of housing has been Gunghalin Hill. I was always surprised when living in South Bruce - backing on to Gossan Hill - that we did not record Mynas there, when they were very evident in Emu Ridge and Aranda (but I rarely recorded House Sparrows or Common Starlings in SB either). For people's interest I attach a graph showing values of A and F from the GBS. I suspect that the decline in F is as much due to a small number of new sites not having Mynas than the range contracting. The drop in A clearly shows the decline in abundance. I'm now off to Pt Vila for a week: another place in which the rats with wings are far too common. My memory was that the playing fields next to the Australian High Commission were graced by 500 of them when I last visited. Martin On Fri, Feb 27, 2009 at 10:04 PM, Bruce Lindenmayer <> wrote:
