Vicki Parslow Stafford's comments are spot-on, re loss of smaller bird
species from ruthless tidying up of exotic vegetation in local parks. I
believe that one reason we still have Superb Blue Wrens about in
suburban Melbourne is that we stll have so
much blackberry everywhere!
I am glad to say that we have been able to convince our local Banyule
Council of this too. A major effort, led by Warringal Conservation
Society from 1989 on, and other bodies as well, to re-establish local
indigenous flora at Banyule Flats concentrated on establishing
understorey plants, as well as eucalypts, before the removal of
brambles, hawthorns and other nasties. This has definitely helped native
species in what was formerly an overgrazed cattle pasture. We now see
Bronzewings under the wattles, at any rate when there's any seed to pick
I also wish to second Graham Fry on not planting hybrid Grevilleas,
which attract aggressive Wattlebirds and Noisy and Bell Miners all year
round to the detriment of the smaller birds. Try for indigenous local
flora whenever possible - it works.
