[FRIAM] While walking to get tacos...

I was curious about the magpies. While I occasionally see them on Upper
Canyon or in the Sangre de Cristos, I have never seen them further south
than Patrick Smith park. I was curious why there would be such a sensible
boundary/frontier, usually keeping my junior evolutionary theorist
speculations to myself. It makes sense that the West Nile virus could have
knocked out much of what was here and that now I am witnessing the southerly
procession of a population growing back.
