I must move this along. Here is 7th and final one. Getting easier, perhaps?
Beginning in the late 1970s, this species has achieved a marked increase in its urban populations. This seems to have begun in Adelaide, where the influx was attributed to inland drought. It has adapted to breeding
in suburban gardens, quite noticeably in Canberra. Now, it might be Australia’s most urban native bird species (as measured by numbers in town versus non-town areas).

Here are two more species. Some would see these as particularly associated with Canberra, where they are able to take advantage of different feeding opportunities.
Fifth species. This is a common one, being noticed recently even by non-bird-people as present in quite large numbers in the suburbs. It is suited also to Melbourne suburbs, less so to those of Sydney except in the west
(Penrith, Camden, just in the 50km).

Sydney 10,128

Not in Perth or Darwin
Sixth species. A favourite of some people, often heard in transit. Go to particular places to find it. Doesn’t breed around Canberra, so far as I know. Comparable numbers in Canberra and Melbourne, which have similar
large numbers of active recorders, I would think, area for area.
Canberra 17,174
Melbourne 14,824
Brisbane 7,189
Sydney 4,986

One more species to come, then answers and conclusions

And now a common widespread species. A comparison of records for different areas indicates, in my view, where you will find the most active recorders as well as giving some information about distribution, and of course
where records can be best captured by a square. A variable polygon of fixed area would be better, but too much work. I believe ALA maps exclude records where there is poor information about location. As Canberra is emerging as the recording capital of Australia,
an attached image shows the process used here.

As some of you might have feared, I have a couple more Canberra bird species. Same procedure as before. I should mention that Atlas of Living Australia brings together eBird and BirdLife Australia records and those
in first RAOU Atlas and in many older sources. As a guide to distribution, the earlier records are now tending to be overwhelmed by the huge numbers of eBird records, although you can select sources as well as particular decades. I’ve used all sources, all
years.
Second species
Not an urban species. The 50x50km square had to be placed carefully to capture enough records to put Melbourne at top of list. (Compensation for the D’s poor AFL season)
Melbourne 5236
Canberra 4876
Sydney 3698
Hobart 157
Adelaide, Brisbane, Perth, Darwin all zero.
Third species
Brisbane 407
Canberra 332
Sydney 249
Adelaide 118
Melbourne 79
Perth 16
Darwin 4
Hobart 3

Using the Atlas of Living Australia, I made a 50km square for each of the eight State/Territory capitals. Each was positioned to catch most of the available records of this native bird species, while also taking in the
relevant CBD. This was the result –
Brisbane 2203
Melbourne 1226
Sydney 966
Canberra 430
Hobart 154
Adelaide 49
Darwin 4
Perth 1 (museum specimen only)
Hints - As ALA records go, these are low numbers for a species, White-faced Heron for example having over 700,000 records. Most records of this species are near the capitals, presumably indicating acceptable habitat and
following the rule that records generally come from the most convenient places for observers. However, South Australia is an exception because most records (253 in one 50km square) were more than 50 km from Adelaide.
Which species? Please don’t reply to list in case people want to think about it.
