The Basking Spot: Hovabators – March 2013

By Jennifer Greene

With Spring on the way, many reptiles are beginning to emerge from brumation or their winter cool down period, and breeding is starting.  Your reptiles will be courting each other and breeding, and love is most certainly in the air.  Now is the time to start considering how you are going to incubate your eggs when they come, not in two months when the eggs have already arrived!  With this in mind, this month’s basking spot will discuss the ubiquitous and easy to use Hovabator incubator, of which there are 4 commonly available models.

The Basic Model – The 1602

The basic model is the 1602, which is coincidentally the least expensive.  It has no frills, no fancy extras, but it is reliable and extremely simple to set up.  It arrives with the top nestled inside the bottom, with the heating element and all the equipment inside already set up.  The only thing you need to do is flip the top over and put the wafer thermostat in.

Now, if you are naturally blonde like I am, putting in the wafer thermostat can be deceptively difficult.  The first time I put the thermostat in, I put it in backwards, which resulted in my incubator running at full heat for the 6 hours I had it plugged in that way.  As you can imagine, that is not what you want the incubator to do.

This is what the wafer looks like when it is the correct side up.

The correct way to install the thermostat wafer is to have the “innie” part screw in to the control rod that goes all the way through the lid of the incubator – for more details, please view the video linked here.

The bottom of the wafer has a button on it that rests on the little needle that determines temperature.   Screw the thermostat into the control rod, and then gently start turning it until you hear the wafer click into place.

Alright, with everything in place, now all you have to do is plug it in and get your temperature dialed in!  I highly recommend getting your incubator ready to go at least several days, if not weeks, before you have eggs to place inside, as the incubator does take 6 to 12 hours to heat up and then be calibrated.  You’ll have to turn the control rod to increase or decrease temperatures as needed.  You may want to consider adding a thermostat to your incubator, and leaving the control rod turned up high so that the thermostat controls the on/off of the heat element.

The Next Step Up – the Model 1582

The basic model 1602 incubator comes with only small picture windows and no frills.  If you are setting up your incubator in a classroom or on display, or if you just plain want to be able to see your eggs easily, the 1582 model comes with a large picture window over the entire top of the incubator.  Set up and use of the incubator is the exact same, but for a small increase in cost you can see the entire insides of the incubator without having to remove the lid.  This will help keep temperatures consistent within the incubator, and prevent the loss of humidity that happens each time you open the lid.

The Turbofan Incubator – the 2362

Don’t need a big picture window, but you do want to prevent air from settling within the incubator and creating discrepancies in temperature between the top and bottom of the incubator?  Then you want the model 2362, the Turbofan Incubator.  It comes with a small fan in the top of the incubator that keeps the air moving, ensuring that your entire incubator is one consistent temperature from top to bottom.  You will have to monitor your humidity a little more closely when using a Turbofan incubator, as the air movement can cause moisture to evaporate a little more quickly than when the air is stationary within the incubator.

The Best of Everything – the 1583

Lastly, if you just want the best of everything, we also carry the 1583 model incubator.  This incubator comes with the big picture window so that you can see everything happening inside the incubator, as well as a fan in the top to keep temperatures consistent!  This is the top of the line incubator, and ideal if you want to be absolutely certain nothing goes wrong and you can easily see and monitor the inside of your incubator.

Any and all of these incubators can be hooked up to a thermostat for maximum control over conditions in the cage, and I highly recommend the use of a digital thermometer to easily see temperatures in your incubator without having to lift the lid and check the mercury thermometer included with the incubator.  Hovabators are a consistent, easy to use incubator that are perfect for nearly all egg incubation needs, making them perfect for the beginner or even the experienced herper needing a simple incubator for a side project.

The Language of Love: Breeding Behavior in Reptiles and Amphibians – January 2013

Introduction

For most of the country, it’s the middle of winter.  Cold storms are moving through, the thermostat is turned up on the furnace, and going out in anything less than a parka is out of the question.  Your herps, however, are likely blissfully unaware—either because they are basking in their own temperature controlled enclosure, or because they are sleeping it out until the Spring.  This doesn’t mean though that they aren’t getting prepared for breeding season.  As your temps start to warm up here in the next month, your pets will be undergoing physiological changes that will prepare them for breeding season.

Whether you have snakes or frogs, monitors or turtles, most of their wild counterparts have a well defined period of time when the conditions are just right for procreating.  In the tropics, this may be the start of the rainy season.  For creatures living in the temperate zones (which is most of the U.S.), this means the beginning of warmer days and milder weather.

This is also the time that most of our pet reptiles and amphibians begin to gear up as well.  The means of communicating the readiness to breed is different from species to species, but there are some common types of communication when advertising love.  As we get ready for springtime here at the Reptile Times, we will be discussing the many ways in which our ectothermic (aka ‘cold blooded’) animals attract and choose mates.

Green Tree Frogs like this one are found throughout the East Coast of the US

Part I: Auditory Announcements

Although we initially rely pretty heavily on appearance when attracting or finding a mate, many species would find all of this primping and grooming a waste of time.  For most anurans (frogs and toads), the voice is often the most important tool to attract a mate.  But why?  What is the benefit of vocal communication, and how can that help to find a suitable partner?

Well, think about the areas in the world that have the highest densities of anurans.  These are wet places with dense vegetation, such as rain forests.  Even if you have good eyesight, it won’t help you to find other small, cryptically colored frogs hiding out under leaves and in small pools of water.  With so much thick foliage, it won’t do much good to see well.

Chorus Frogs, like this one, get their name from the distinctive calls they are known for making

Picky listeners

Sound, on the other hand, carries far, even when visual barriers are present.  Having a strong voice means that you can be heard over a greater distance, thereby increasing the number of listeners (and potential mates).  As for most animals, it is the males that do the majority of calling.  Females tend to be choosy since they typically have a very limited number of reproductive opportunities in a given season.  Making eggs is taxing, and, depending on the species, they may only have one opportunity to have their eggs fertilized.  In that case, finding a mate becomes a choice that could be the difference between their genes getting successfully passed on to the next generation, or not at all.  If the chosen male doesn’t pass on good strong genes to your offspring, they may not live long enough to have offspring of their own.

Males, on the other hand, typically have a very different take.  Where females are all about quality, males are all about quantity.  Unlike females that produce large, energetically costly eggs, males make millions of small, energy efficient sperm.  In most cases, the number of females they can breed with is dependant primarily on how many they can convince.  So when it comes to attracting a mate, males are usually the ones with the tougher job.

Size matters

You have likely heard the saying “appearances can be deceiving,” but it’s hard in the animal world to disguise a voice.  Vocalizations, or calls, are usually closely tied with the size of the animal making them.  For example, a small frog can’t make a deep call, just like a snare drum will never sound as big and deep as a base drum (think of an American bull frog versus a chorus frog).  It’s all about the size of the instrument, and it’s hard, if not impossible, to alter a call enough to trick a discerning ear.

But why is being bigger important?  It isn’t always, but being bigger usually means that the male is older, has more access to food, or both.  If a male lived long enough to become big and can make a nice booming call, it likely has good genes that have allowed it to find food and escape predators.

Standing out in the crowd

Often times, males stay put and call while the females seek out the one they wish to breed with.  In some species, the males form a lek, which is essentially a gathering place where they can show off for females.  The females come to the lekking spot, and can suss out which male would be best to breed with.  In some cases, the mere act of being able to participate in the lek is the only qualification a male needs to attract a mate.  Males that live long enough to make it there every season are usually those that are higher quality, and therefore suitable for a choosy female.  In other species, females will find vocalizing males from a distance, led on by the sound of their call.  Only males that have strong, attractive calls will be sought after, meaning that males with less attractive ones will be left singing to themselves.

An important point to make here is that every species will have its own particular call structure and/or frequency.  Ideally, females will only be attracted to the call of their own species.  If they weren’t, it would be a waste of their time, and they wouldn’t be likely to reproduce.  They are tuned in, so to speak, to the vocalizations of their own kind, and discern between calls that are within certain acoustic parameters.  Some of them within those parameters just happen to be more or less attractive.

This is an important element in vocal communication because of possible interference from other species.  In your mind, go to that lush rain forest with all of those frogs.  Think of how many species there are, and how that might sound.  Pretty confusing, for an animal that is relying on sound to find a mate.  Animals need to be able to ‘filter out’ the sounds of other species, and focus in on those of their own.  Not an easy task for us, perhaps, but one that comes naturally to even the most inconspicuous little frog.

This little Chorus Frog was caught in a surprise spring snowfall – he hopped away to sing another day!

Curtain call

As the country begins to thaw out in the next few months, we will start to see our reptiles and amphibians perk up, and get into breeding mode.  This is the time of year that is often most rewarding to serious herp breeders and casual hobbyists alike.  Your pets begin to wake up, eat more, and, often times, start looking for a mate.  The way they do so depends on the species, and it can make for truly interesting behavior.

Although we rely heavily on sight when finding a potential mate, many animals use other senses to discern a good partner.  For frogs and toads, it’s all about the voice.  A call that sounds out over the rest is sometimes the most enticing attraction for a female, making it a male’s most important asset.  However, sound is not the only way that animals communicate and find mates.  Next month we will be discussing how some species use chemical cues to find and attract each other.  In the mean time, keep an ear out for local frogs and toads as they get ready to sing their hearts out in search of springtime partners.
