When in doubt, draw a graph

It's time for more fun with trend graphs....

I obtained average temperature data and average rainfall
data from 1970 to 2000 and compared it to the adjusted
Orange-crowned counts from CBC's for the same period.


And I found correlations. The weird part is that the
correlation is rainfall dependent more than it is
temperature dependent.

In drier than average years, temperature matters, but in
wet years temperature does not matter. However, more
Orange-crowns occur in very wet years compared to average

Since this has been a very wet year, we may have an
explanation for at least some of the stuff we've been seeing.
And it fits well with Wayne's Pineapple model...

There have been tyrants, and murderers,
and for a time they can seem invincible,
but in the end they always fall.
Think of it...always.
