One: Observer Affect:
overall, the observations that we make here are a remarkably ‘clean’ insight into emu life. What must be kept in mind is that the house-clearing is a ‘hot’ environment because of the abundance of its food, both the fruit trees and pasture, and what S.E. hands out. S.E. notes that he has seen far less ‘power play’ activity when observing birds on other pastures.
Otherwise, the birds are often distracted from doing their ‘natural’ stuff by their hope for a bit of Yummies – I sit down to observe . . . the birds mosey over to me. However, I don’t think it changes much. For example, my observations of E.P. roosting didn’t seem skewed by my presence. The birds sat about fifty yards up an aisle; S.E. sat at the end and watched. At most, they may have headed to the house-clearing a minute or two earlier, looking for their brekkie, because they knew I was up and about.
Two: temperatures:
S.E. was surprised by some temperatures in the Report. He has perhaps overestimated sometimes . . . and perhaps not. Oodnadatta got a mention at 129F. What surprises S.E. is that such a ‘low’ temperature was the record.
Accuracy is a very important thing to me. I have on several occasions read historical texts that reported higher temperatures. I have on several occasions spoken to locals who assured me that temperatures, generally monitored by individuals in those days, do rise above the ‘official’ estimates. A guy I trust well told me that when he was carting seismic rigs in the Tanami Desert, it hit 134F in the ‘met. box’ while he was there.
It remains to point out that official readings are in-the-shade readings.
Three:
S.E. needs to be more diligent as he stares at the satellite photos. The ‘equation’ requires identifying all the water sources – all – and S.E. missed a couple. (There’s one tucked away only about five hundred yards down the river bed from the last one we visited.)
Whatever, though: we are doing high-quality work, readers; and the Basic Equation is both correct and still a work in progress:
We can gain an insight into population density in different districts by becoming conversant with the relations between food and water and fences and and and . . . – and that is what we are patiently doing. Still, it was a blue to overlook several waterholes.
