This has to be the weirdest thing that ever floated by me in the
river. They were stuck together in death lock, each wanting to kill the other
first. My guess is that the falcon snatched up the tasty snake, and it somehow
got its tail around the falcons neck, strangling it in midair causing both of
them to crash into the Comal river. They are both alive and well, considering.
