I saw the Brisbane Bittern perched on one of the chains anchoring the riverside helipad as I was cycling home from work, which reminded me to introduce the concept of commuter counting [or twitching for those who like to think in those terms]. Commuter counting is ultimately non-competitive as no one else can replicate the conditions under which you put together your list.

I decided to start a count when I saw the Brisbane Bittern and the Brisbane Rail on the same day in the vicinity of QUT, and have so far picked up 38 species along my 12 km commute from the southern suburbs to the Brisbane CBD. This is somewhat less than the number of species that are about, but there are strict rules governing the commuter count:

1. No deviation - all species must be observed while travelling along your regular, pre-existing route - no deviating to search for additional species is allowed. 2. No mode-switching (eg walking the route rather than cycling) to increase your chances. 3. No slowing or stopping to search for birds - you must observe the birds while travelling at your normal speed [which in my case is an average of 30 clicks when I am not held up by traffic]. You can however stop or slow to identify a bird that you have already observed while in motion. <Mechanical failure is the only non-traffic related reason for stopping>
4. No aids (field guides or binoculars etc) are allowed.
5. On the positive side, both audio and visual identification are allowed.
6. The count starts/stops at your property boundary.

Commuter counting is a good challenge for a cyclist as there are plenty of distractions [cars, pedestrians and other traffic hazards, the tendency to drift into the zone, the need to keep the speed up, and the difficulties of observing high-flying birds]. There would be less of a challenge for pedestrians, but they would probably have a shorter route and so likely to pass fewer species [ie they would observe a higher proportion of a smaller field]. Car drivers would find the challenge a bit hazardous. Bus and rail passengers would scope to keep an eye out for birds while waiting for their conveyance and then be beyond temptation while on the move ...

Anyhow, the species I have been able to pick up over the last six weeks or so are as follows ...
