"All'z we got out here is them
rattlers and bullsnakes." I'd often
hear the locals say...
Bullsnakes? I knew they must
certainly mean gopher snakes. All
over the Northwest however, folks
out in the country still call them
bullsnakes. And it's so awkward
trying to get them to see the light!
"It's jest a snake... ... a bullsnake."
There are no bullsnakes in
California. Bullsnakes live in the
Midwest. So why the common
misnomer?

An answer might be found in the definition of the genus. Both snakes belong to
the genus Pituophis, which includes pine snakes.
One apparent translation of the name Pituophis suggests that the Greek word
"pityos" -meaning "pine"- was used; another translation from the Latin
"pituitarius" refers to "phlegm" or the hissing sound that comes with perhaps the
clearing of phlegm. (Gross!) We're not fluent in Greek or Latin, but the former is
the most widely accepted, though the latter seems more applicable.
One of the features all Pituophis (pine,bull, and gopher snakes) share is a
modified flap in front of their epiglottis enabling them to sound off a loud gutteral
hiss. This hiss is used to warn away threats; combined with a flattening of the
head and and the rattling of a rattle-less tail, most of these snakes can put on a
good show. It's usually a bluff, but larger Pituophis can inflict painful bites if
they're pushed too far. Most Pituophis are powerfully built and rather large
(among some of the largest snakes in the U.S.), and this only makes their
defensive behavior all the more impressive. It is quite understandable why
many people might envision the personality of a bull waiting to charge; and the
Bullsnake is popularly known to have quite an attitude.
The Bullsnake possesses colors and patterns similar to those of its western
cousin - the Gopher Snake, however appears to have a more robust build like
its eastern neighbor - the Pine. Now... most people don't like snakes, and
during an encounter, if they don't kill it first, they usually want to get away from it
as soon as possible. The "You seen one snake, you seen 'em all!" mentality
doesn't go a long way for making a good identification. Imagine such
perceptions among the countless settlers moving west to California in the
1800's; they must have thought this bullsnake was everywhere! Thus, it is very
likely that the name moved west!

The Audubon Society Field Guide to North American Reptiles and Amphibians (1979)
lists 10 snakes belonging to the P. m. melanoleucus species complex: These include
the Northern Pine Snake, the Black Pine Snake, the Florida Pine Snake,and the
Louisiana Pine Snake; the Bullsnake; the Pacific Gopher, the Great Basin Gopher, the
San Diego Gopher, the Sonora Gopher, and the Santa Cruz Gopher Snakes.
That was then... This is now...
Recent advances in the fields of genetic research have provided some enlightening
facts about the Pituophis family tree. Currently 5 species and 18 subspecies of
Pituophis are recognized. The list is as follows:
Northern Pine Snake (Pituophis melanoleucus melanoleucus)
Black Pine Snake (P. m. lodingi)
Florida Pine Snake (P. m. mugitus)
Louisiana Pine Snake (Pituophis ruthveni)
Mexican Pine Snake (Pituophis deppei deppei)
Northern Mexican Pine Snake (P. d. jani)
Striped Mexican Pine Snake (Pituophis lineaticollis lineaticollis)
Guatemalan Pine Snake (P. l. gibsoni)
Pacific Gopher Snake (Pituophis catenifer catenifer)
Great Basin Gopher Snake (P. c. deserticola)
San Diego Gopher Snake (P. c. annectans)
Sonoran Gopher Snake (P. c. affinis)
Cape Gopher Snake (P. c. vertebralis)
San Martin Island Gopher Snake (P. c. fulginatus)
Cedros Island Gopher Snake (P. c. insulanis)
Santa Cruz or Channel Island Gopher Snake (P. c. pumilis)
Coronado Island Gopher Snake (P. c. coronalis)
...And last but not least, is the Bullsnake (P. c. sayi), currently recognized as a sub-
species of the Pacific Gopher.

"See?! I told you it was a bullsnake!"
No... Technically, a bullsnake is now a gopher snake!
"Well how 'bout them rattlers then?!"

Members of the genus Pituophis share habitats with rattlesnakes throughout most of
their North American range. Additionally, like many of their distant colubrid cousins
(i.e: rat snakes and kingsnakes), species of Pituophis will often take on a defensive
stance similar to that of rattlesnakes. The aforementioned tail-rattling appears to be
classic mimicry. It is understood that a rattlesnake uses its rattle to essentially warn
off any animal it might perceive as a threat. In many cases this relates to large game
animals and the old saying "Don't tread on me." Why get trampled by a bison if you
can tell it to get out of the way! The question however often comes up as to whether or
not the rattle came before the rattling behavior witnessed in colubrids. We ask "What
use is a rattle if you don't know how to rattle?" (Duh!) "Was the rattlesnake the first
snake to rattle?" (If so, did the tail mechanism evolve later?) "Does a bison or a horse
know the difference between a Bullsnake and a Prairie Rattlesnake?" (If so, what then
would be the purpose of Pituophis rattling?) Perhaps most likely, "Might most large
game animals be spooked by any or all snakes?" (If so, is rattling just an old
defensive instinct among a variety of snakes with the rattlesnake being the only one
better equipped?) Without all the facts (Sorry!) we are inclined to believe that vibrating
the tail is just a great way for any snake to make noise. Loose leaf litter helps if you
don't have a rattle! But why then will Pituophis go the extra mile and engage in further
supposed mimicry by flattening the head? Maybe this behavior is only related to the
positioning of its mouth while hissing. Or perhaps rattling isn't enough to fool a threat
that does know the difference between the snakes; thus, making the head look wide
like a rattlesnake may indeed help keep the hooves away... Not that the snake knows
this, it's just that it works. Likewise, many Pituophis, especially gophers and bulls
don't know that their inherited color and pattern mutations resemble those of
rattlesnakes, it's just that they too may help with the disguise.
Unfortunately, since the arrival of the wagon trains up to the present, countless
gophers and bulls have been and continue to be killed due to the fact that they
resemble and often behave like rattlesnakes. What might have once been a deterrent
is now an invitation for hapless slaughter.
Once when I was thirteen years old living in San Diego our neighbors told us that they
had killed a large rattlesnake and had thrown it over the fence into the canyon below,
and that if I wanted to see it I should just hop over the fence and take a look. What I
found was a headless San Diego Gopher Snake. I was appalled. A senseless death.
And the largest gopher snake I'd ever seen (even now). We measured it at six feet
without the head. What a survivor it must have been: Avoiding eagles, hawks,
kingsnakes, and other predators; simply surviving the elements for so long Snakes
never stop growing. They just grow more slowly after they reach full sexual maturity. It
is very rare to encounter such a large specimen so close to civilization. The first
humans in a new area usually "take care" of the big ones early on. This however was
around 1980 when North County San Diego suburb projects were popping up
everywhere. Our neighborhood was only four years old. Around us virgin fields were
being bulldozed left and right, and this probably roused up some of the remaining old
timers. In fact it should be known whenever you're developing in snake country you
should count on seeing emergency snake migrations. Growing up in this area
through high school I imagined all the wildlife here being squished into canyon
corridors surrounded by buildings and pavement, and the only way to make it to the
next canyon was to find a good sewer pipe or risk getting run over by automobiles.
The imprint in my mind of this snake will last a lifetime. This old timer got the shovel.
There would have been more dignity in having been killed by a hawk. So since it didn't
become food, I made the decision to skin it (almost 7 feet after the stretch) and turn
the snake's legacy into an educational tool by donating the skin to my 7th grade life
science class.
