More coming, but in the meantime…

I’ve got two posts I promise to write. The first on systems biology from a talk I attended by Leroy Hood. The second on interspecific territoriality and convergent evolution. School and birding have kept me busy.

In the meantime, I’ve got a good picture to share.

While walking down a trail this weekend, birding at in Friedrich Park on the edge of San Antonio, my mother-in-law screamed and jumped back. A 3 to 4 foot Black Rat Snake (Elaphe obsoleta obsoleta) sat stretched out across the trail.

I had to convince the snake that I wouldn’t stop chasing him until he allowed me some pictures, but once I’d won that battle, he sat still for surprisingly long time.
