Snake season as we know it is over. Here's some facts about snakes during the colder months, and why the cold is just well as their breeding cycle and why they are important as the heat.
On this post I'll be discussing 'brumation'. What it is, how it works and how you can keep safe as well as being educated, as cold has value to snakes.
1.Q
What is 'brumation'?
1.A
Brumation is similar to hibernation, though there are distinct differences. Hibernation is where a mammal such as the well known example of a bear goes away for the winter and doesn't generally leave their den. They remain in an inactive state and don't reappear until spring where it's warm.
Brumation varies from this. Brumation is where for example a snake becomes far less active, though once a month or so may come up on a warm day to sun such as 12⁰c days or higher. If we're in for a few warm days then they may even squeeze (pun intended) a small meal. Nothing too large as they need heat to digest otherwise they will regurgitate or become ill from it rotting.
2.Q
Where do snakes go to brumate?
2.A
Snakes will go to various places such as under large rock crevices, hollowed out logs, or anywhere else they will they can hide out to avoid being disturbed. I've even pulled multiple Brown snakes from the same hole in the ground of man made structures. They also can hide out down in abandoned rabbit holes.
3.Q
Why is the cold weather so important for snakes 🐍?
3.A
Snakes like other reptiles need their body to cool down, otherwise they are infertile.
Unless they cool down, the snake may try to mate though both genders will be unable to reproduce. They rest up, lose some body weight during this season thus coming out in spring ravenous for their prey. Females upon becoming gravid (carrying young/eggs) will be unable to eat as pregnancy progresses. She needs to eat, and eat well while she not only carries eggs, though also sits on them.
Fun Fact: While Eastern Brown Snakes are known to be solidarity, during brumation they can be seen sheltering in the same dens in order to keep warm and safe from the cold.
4. Q
Can you tell which snake is male and which is female by looking at them?
4.A
The simple answer, yes. While I'd never encourage anyone to go in for a closer look, due to safety concerns, telling the gender of a snake is as simple as looking at it's tail.
The tail on a female snake will go from fill width of the snake down to a short little tail, whilst a males tail tapers off gradually. Why this makes sense is as follows.
Male Snakes like other reptiles contain a hemipenes. What this is two sets of male genitalia in a prong like look which are stored below the cloaca (the vent to which they mate, urinate, defecate, give birth or lay eggs from. The males need this extra room for their genitalia. Female snakes on the other hand do not. Their reproductive system including eggs or live young are stored above the cloaca. Having a female ar your place is sure to attract males seeking a mate during the breeding season. They will leave their hiding hole and come out to feast. Once their bodies have cooled, warmed up and fed they will then look to mate.
5.Q
Keep safe in winter?? There's no snakes about!! Why?
5. A
Yes, this is true. They aren't out and about though they don't disappear from the planet. They hide away in all sorts of places where there is inactivity such as inactive barns, sheds, water pipes and others. You could be out working and go to move a rock or log and find a sleeping snake or even a few. While winter poses far less risk, take precaution such as checking as best you can and ensure you have full view of where you're walking. Especially on a warm winters day.
6. Q
What should I do in winter if I see a snake?
6. A
If you see a snake brumating, leave it be. It is likely cold and thus hardly able to move or react like they do in heat. If it's in your property in a place it shouldn't be for safety concerns, feel free to call me for safe and professional removal.
Lastly, there's no reason to fear snakes. The fear we have is what they venom could do to us, rather than understanding what their venom is designed for. Their venom is designed firstly for their prey, and if required also for something that poses a risk to their safety. Like the kangaroo, koala, echidna, wombat ect they are one of Australia's beautiful native animals who like others only seek food, shelter and safety. They want to avoid us at all costs though in their hunt for the three mentioned above needs sometimes come into contact with us. What happens in these situations depends on us. They help farmers out to keep rodents under control. They help keep mice and rats away from the eggs in your chicken nest.
