PLease do not take this to hard but hibernation is not needed. I am one of the first to produce montane kings, of many types, and few world firsts. Yet I did not need to brumate or hibernate.
I keep saying this yet few if anyone gets what snakes actually do. Its not about hibernation, not in the least. Its about energy conservation. All snakes use cool temps normally, then seek heat when needed.
Wild montanes seek temps in the fifties and sixties, normally all times of the year. Of course seek more heat when needed, they use it and quickly return to a base cool temp.
In their world, they get summered if you will. hahahahahahahaha. Summered is when the temps are too warm to conserve energy and they must feed heavily just to maintain energy levels. During these conditions, they cannot reproduce, not in nature or in captivity.
In captivity folks somehow think they require ONE set temp. Which is not what they do. Keepers pick a horrible AVERAGE temp and fine tune it to degrees of a degree. Like 82.4564F hahahahahahahaha
The reality is, kingsnakes pick temps from the forties to about 100F. And everywhere inbetween. They do so by need. A few degrees more or less is meaningless. They will just move sooner or later to adjust.
For instance, large prey items, they choose hotter temps for short periods and then move to cooler temps. Smaller prey items they will start with cooler temps then the large prey items.
When females cycle, they require elevated temps for very short period of time. etc etc, this includes the building of the immune system, shedding, and growth. Growth occurs at a range of temps, but is accelerated at higher temps.
Our misconception is, we think if they stick to one temp, that is bask all the time. Thats the right temp. Which could not be farther from the truth. Their design is to acquire heat to DO something, and acquire it quickly, then do the something. To bask is dangerous. If they are out, they need to be at fully operating temps. And they need them quickly. So the shortest time sped basking is the optimum. Not the longest.
I was very lucky, when I started breeding kings, there was no protocal or recipe. It simply wasn't done. Which means, I was not prejudiced by anything other then the results from the snakes.
I tested constant temps and constant lite. I also tested hibernation.
That is, I kept kings(getula) at between 82F and 85F and constant lite and bred them for decades, their cycled for the first clutch, every 11 months and ended up producing eggs in every month of the year. They also multiclutched, which was unheard of at the time.
I then tested this on montanes and bred many species successfully.
Then I learned if you offerred a range of temps, you the keeper did not have to make important decisions. Like the things you question now. As it is, you create conditions where you become the fall guy, which is any business is WRONG. All you have to do is offer a range of temps and the snakes will breed, feed, grow, etc, all on their own accord. Which is something we negleck. We think WE have to control them. How weird is that?
I have many many world first breedings of several types of reptiles. Some folks ask me, how does it feel to do that. My normal responce is, relieved. The reason is, these animals have be breeding, hatching, growing, etc etc etc since before man was man. ALL ON THEIR OWN and under many different conditions. We do tend to be a hinderance to them. In otherwords, they do not need us. They are fully capable to take care of themselves. All we have to do is offer some very very very basic conditions to allow them to be KINGSNAKES(insert any type reptile here) Allow them to do what they "know" how to do.
The arguement about hibernation and montane kings is kinda silly as montane kings only occur in warmers areas of our country. And of course all thru mexico. Of course your going to say, they occur at elevation. Hmmmmmmm well, I have been part of a longterm montane reptile study(20 years) and we find montane snakes active all year around. The three worse months(actual data) for outside activity is, Jan, may and june. During most winters, we find far more out in the winter then during the summer. Animals per man/days. During many winter days, I can find them several times faster then my partner/s can process them. And that makes him/them mad. hahahahahahahahaha.
Back to the point. The recipe of hibernation, is only a recipe, its not about the animals, its mainly for keepers who do not understand the animals and have to follow something in fear of failure.(blunt huh?)
Simple exceptions us longterm keepers have seen. Keeping females out of hibernation because of ill healt. Hmmmmmmm if they regain their health, they reproduce anyway, and often on the same day they laid when hibernated. Yes, I also hibernated snakes too. In fact, I was amongst the leaders in that. The best thing about hibernating snakes is, you can take a break from them. Again, that is about us, not the snakes.
In reality, hibernation and brumate(in nature) are survival behaviors to escape very adverse conditions. Its not about reproduction. In areas where conditions do not force hibernation or brumation, they do not. Which is the vast majority of the areas snakes occur in, 99% of all reptile species are equatorial.
of course, your allowed to do whatever you want, I only hope you could consider(to think about) what the snakes really do. Which is use cool when they want and heat when they want. All you have to do is figure out how to give them those so they will use it. They do have very specific ways to seek these things, and out in the open is normally their last choice. Cheers
