The subject of the Calico corns has turned up every now and again, and a couple of years ago I spent a lot of
time talking to some of the people that knew the most about them, trying to figure out what they were and whether
I wanted to get some for myself. Rather than giving a brief synopsis of what I concluded, I feel it is better to
just present the information I received and let you make your own decisions:

Hi Rich, this is Tim Rainwater

I just got an email from Adam Song in NY and he forwarded me an email
about the piebald / calico corns. I am very interested in finding out
any info you have on them. After looking at the email, I don't know
either of the other gentelmen mentioned. I didn't buy them from either
of them. I was not told that this could even be a problem when I bought
them. I did have the entire group I bought checked out by my vet here
in town. Just a routine check that I have done on everything that comes
in. There was nothing to be found. Two of the snakes had blisters when
I got them, but within a month the blisters were gone and have not come
back. This has been two years now. I figured this was because I keep
the cages super clean. I think the skin may be sinsitive or something
like that. The ones I have are also lively and feed great. I haven't
lost any of them and none have gotten weak that I have noticed. I am
now raising two generations of them since I got them and have not seen
any problems. I have several that have the white markings and they have
never had the blisters. Are you sure we are talking about the same
bloodline or even genetic mutation? If so I am very interested to
figure it out. I call them calicos because I hatched out a piebald corn
in 98. One that looks just liek the piebald ball pythons and it hatched
that way. This is what I think of when I think of piebald. I hope to
line the possible hets up right next year and prove the gene genetic.

Thanks tim

Hi Rich,

I'll try to provide some answers to the points you brought up.

The original wild-caught female piebald had scars from the blistering that
must have accompanied her depigmentation, which had occured while she was
still in the wild. All specimens that we saw undergo the depigmentation
also showed some degree of blistering - in direct corolation with the
amount of discoloration. Blistered areas on a couple of the snakes were
examined for causitive agents, but none were found. The best guess we were
able to come up with was that the blistering was a manifestation of an
autoimmune response to pigment or to pigment-producing cells. Only one
indication of possible environmental factors affecting the blistering was
noted - on one female, the depigmentation, and hence the blistering, seemed
to be more severe at warmer temperatures. This was on a female that
underwent almost total depigmentation, and the process was consistent with
heightened autoimmune response at warmer temperatures. Cleanliness of
caging does not appear to be an issue. My wife is a microbiologist/med
tech., and is extremely cautious about hygiene issues in the animals she
keeps.

>Since I am certain Tim has not had these animals long enough to

No, he didn't get any such information from us.

> ......................I would like to know if you can provide me with

The onset of depigmentation is synchronous with the snake reaching breeding
age. You could probably speed up the process by keeping the snakes warmer
and feeding them more heavily. However, this could accelerate any
autoimmune responses, hence defeating your efforts at minimizing blistering.

>Is Tim Rainwater now the sole source for these animals?

We gave a small breeding colony to Warren Carbonel, and at last contact he
was having some success at reproducing the trait. This was some time
before Tim Rainwater got his specimens. Unfortunately, I no longer have a
means of contacting Warren. If you can locate him, he may be able to
provide you with information or specimens. We kept no piebalds for
ourselves, so we are out of the business with them.

>And lastly, does a mother and father exhibiting this trait produce 100
>percent babies that also exhibit this trait?

No. We never got to the point of being able to produce piebald offspring
in a predictable manner. We could produce litters in which the effects
were sure to show up, but not in predictable percentages, and nothing close
to 100%.

One other point to keep in mind - depigmentation was only one of the
effects. Some would suddenly start growing weak to the point that they
could not kill prey, and eventually were unable to eat or drink.

The symptoms were in some ways similar to lupus in humans - which primarily
manifests in females, onset starting at sexual maturity. Depigmentation
can be the most obvious indication of onset, but a host of other symptoms
can also be present. Lethality follows the same pattern, as well. Lupus,
of course, is an autoimmune disease.

>Thank you for your time and any help you can give me.

Any time. I do hope someone pursues the issue of this form of "piebaldism"
and comes up with real answers. If you do get any specimens and work with
them, I hope you share your findings.

If you have any other questions, or care to swap ideas on the topic, please
feel free to contact me.

Rich,

The animals Tim got came from us - a friend/neighbor of ours (Larry Sedrick
- and I may have spelled the last name wrong) brokered the sale. The ones
Warren got we gave to him for free just so that someone else would also be
working with them. About four or five years ago I went to the San Diego
breeders show and sold a couple of the siblings of the first captive-born
piebald, and I have no idea who the buyer was. That, by the way, was the
first time we "officially" used the term calico to describe them. We had
used the term between ourselves prior to that, but had not marketed the
animals under that name or published the name before the San Diego show.

Bill

OK. A brief history is in order. Dwayne Collins was the "original"
owner of the wild-caught female piebald. The quotations are on
"original" because I don't think he actually caught her, but bought her
from whoever did. Dwayne bred her with a normal corn, and sent some of
the offspring to Ernie Wagner, and kept others for himself. Both Ernie
and Dwayne tried breeding the offspring to see if they could produce
more piebalds, but gave up after a couple tries only produced
normal-looking babies. Ernie got rid of his stock, and Dwayne directed
his interests elsewhere. I think Bern Bechtel may have also gotten some
of the offspring from Dwayne, and followed the same path that Ernie
took.

Dwayne was a good friend of ours here in Tucson, but wound up in some
serious legal trouble for which the government relocated him for a
number of years to a federal facility in Texas. During a brief "grace
period" before leaving the state, he was given a few days to wrap up his
interests, at which time he sold the piebald and a couple offspring to
us. Unfortunately, when Dwayne was finally able to return to Tucson, he
was unable to cope with circumstances in his life, and died shortly
after his release.

Through a mutual friend (Dave Hardy), Bern Bechtel heard about Jillian's
success in producing another generation of piebalds, and he got in touch
with her. He was in the process of writing his book, and had a bunch of
questions. He and Jillian had several telephone conversations,
exchanged letters, and she sent him some photos. She was a bit miffed
when she saw the book and found out that he refered to her as a guy and
renamed her "Julian". Bern has caught some minor flak for it, and
there's a couple people in our herp society who now insist on calling
Jillian "Julian" just to tease her.

Back a while Bill Love was in touch with us gathering some of the same
information you are interested in. I think he had known Dwayne, and
knew of the early attempts at producing piebald offspring.

Hope this helps out.

Bill

Hello,

>>>>

I've sent you this copy of my current correspondence to help explain the calico corn controversy from my viewpoint as I've been doing with
Rich Zuchowski recently. PLEASE let me know how you feel I should proceed to best amend the error I made until a revised version of THE
CORN SNAKE MANUAL eventually happens. Thanks, and I apologise for any inconvenience this has possibly caused you.

<<<<

I'll try to answer some of the questions and clear up misunderstandings. Please feel free to ask for clarification in anything you have doubts about.
Meanwhile, don't worry about any errors - no harm has been done and no inconveniences have been caused.

First, as far as the blistering and depigmentation - blistering has ONLY been observed in conjunction with depigmentation. It seems to appear in at
least some degree whenever the depigmentation occurs, and the moe severe the depigmentation, the more severe the blistering. In those siblings of the
piebalds that do not manifest depigmentation, no blistering has been observed. However, other effects have been observed, such as severe and sudden
loss of strength to the point of the animals being unable to kill prey, or eat. A large proportion of the siblings, however, showed no symptoms at all.

The hope I had for the possibility of a strain without the lethal effects (a slim hope, though) is that some individuals seemed to "stabilize" after some
depigmentation occured, and the blisters ceased appearing. In fact, the original wild-caught female had scars from where blistering had occured, but
during the entire time she remained in captivity no new blisters occured, and her pigmentation did not continue to change.

>>>>

>Thus far, Tim hasn't responded to the evidence I provided him that HIS
>animals are one and the same as those that Bill Savary is describing.

<<<<

Tim's calico corns are the ones he purchased from us through a friend and neighbor of ours, Larry Sedrick. He does, however appear to have an
unrelated piebald corn that may be an actual true piebald. I believe he has only one such specimen, and is keeping it seperate from the calicos.

Correct on all points. For whatever it's worth, Jillian and I have lived together for about 23 years, and accept the periodic accusation of being husband
and wife.

As noted before, blistering was only observed in conjunction with depigmentation, but other effects occured without depigmentation. Also, at this

Correct. The strain was first refered to as Calico when we acquired the wild-caught female from Dwayne, but probably the first time any of them were
marketed as Calico was at the San Diego show about 5 years ago when I sold a few normal looking offspring which were siblings of the first
captive-produced piebald.


Hopefully this helps. Feel free to ask more.

Hi again,

I just got off the telephone with Larry Sedrick, the guy who brokered the
deal when Tim Rainwater bought the calico/piebald corns from us. It
appears that our discussions have upset Tim. According to Larry, Tim has
suggested that he wants to sell the snakes back to us. For the same
reasons that we initially decided to sell the snakes (lack of space, lack
of time, and not up to the frustration involved in the project) we are not
interested in getting them back. If either of you know people who would be
interested in taking on the project (with full knowledge of what it
entails), you may want to point them toward Tim. Our original sale was 9
or 10 animals, three of which showed depigmentation, for $500.00. This
sale was brokered through Larry, who may or may not have added a mark-up
(I've never asked him about this). I don't know how much Tim may want for
the animals, but if he's really thinking about washing his hands of them,
the above information may help.

Bill

Rich,

Don't worry about it. I think it's important that the issues
surrounding the piebald/calico corn be known and publicized so that
legitimate work can be done on the strain without people getting drawn
into it under false pretences. You were 100% correct in passing the
information on to Adam Song. Had he been in touch with me, I would have
done the same. Both Jillian and I have tried communicating with Tim on
many of the issues I've discussed with you and Bill Love, but we've
never gotten him to respond to our messages or letters. I think the
current discussions have gotten him to at least confront the realities
of the piebald/calico breeding, and even if he's not happy with the
reactions he's getting, the overall situation should improve. I do hope
someone pursues working with this strain. I think there's a lot that
could be gained both from the pursuit of the depigmentation process, and
from any understanding that comes out of studying the medical
implications of the possible autoimmune process.

Bill
