Sick Birds

Noticed a number of dead birds on the walk to and through campus today.

Maybe I just notice these things more nowadays.
Or, maybe it is the change to cooler weather.

In the meantime here is something to cheer you up

Deaths continue to double each year.
Simplest explanation is that it is growing exponentially in birds (or some other host) with a low co-efficient for transmission to humans, that is constant.
If human-to-human transmission became efficient, the doubling time would suddenly shrink to something like 1-2 weeks.
Else, the incidence in birds must saturate and we'll see a leveling off, or decline, in human cases as the bird host reservoir saturated.
