Pictured:  Joshua Naumann (RNSP seasonal employee)

The veg management crew at the park  was amazed at the confrontation it witnessed
while pulling Scotch Broom at Dolason Prairie.  We saw both a racer and a 'blue-belly"
basking on the same log.  Both saw our approach and disappeared under the log,
where they apparently met.  Suddenly there was a blur of action in a tiny hollow at the
end of the log.  The first three pictures were indeed a blur of writhing coils and shining
blue.  It appeared that the racer was coiling to restrain rather than suffocate.  It had
the lizard by the hind leg and base of the tail.  The fourth picture shows the fence lizard
fighting back by biting the lower laterals of the snake's neck!  The racer actually let go,
and the lizard made a grand escape!  The close-up in the middle shows the lizard's
bite marks.  What a sighting!
