This takes us to the heart of COGland, and into the territory of Philip and Martin.  Below is a slide from my off-the-shelf talk on Canberra birds.   The percentages refer to SITES where the species has been recorded at all in a full year (not abundance).  The first column is derived from Philip’s analysis of the first 21 GBS years, treating those years as a block.  Then, sparrow and starling were firmly entrenched in the Top Ten GBS birds.  In the more recent 2 years shown, the sparrow was not recorded at all in 20% of the (3-hectare) sites.   I need to update the graphic, but the trend continues.  Martin tells me that in 06-07 only 78.6% of sites had sparrows.   Given that that is over a full year, it also suggests that they don’t move around much.
