g'day all,
1
Rory Poulter of the BA Atlassing team has previously commented
about the high number frequency of reports that include the ubiquitous Willy
Wagtail.
They are in "swarms" in many areas that I visit..
And the numbers seem to be increasing and the range
expanding !
And of course they are very aggressive to most other
species.
Could there be a possibility that they may be displacing
other species ?
2
Has the expansion of range of the introduced House Sparrow
displaced any other species ?
3
Or have they both filled a vacant niche ?
Regards, Bob Forsyth, Mount Isa, NW Qld.
Could there be a possibility that they may be displacing
other species ?
