Most snakes don't hibernate, it's only the ones that live outside of the tropics, and that is because of several reasons the most important of which are:
a) food - their prey may be more or less abundant are certain times of the year and
b) outside temperature - because snakes are ectothermic, the majority of their body heat is controlled by the outside temperature. In the tropics, snakes (and indeed, other "cold-blooded" organisms) don't need to hibernate, because they have a perfectly comfortable stable temperature all year. But in Europe/North America for example, these cold-blooded organisms will find it very hard to catch prey in cold seasons (so, winter) because they have very little energy to move and digest with!
Plants open and close at certain times of the day due to circadian rhythms and environmental cues like sunlight and temperature. Animals hibernate at certain times of the year to conserve energy during periods of food scarcity and harsh weather conditions.
Good times for certain animals to hibernate
The seal migrates in winter, because it does not have a fur coat to keep it warm if it were able to hibernate, therefore the seal would freeze to death trying to hibernate. Plus, the seal needs to go into the water daily to keep its skin hydrated, so it must migrate in winter. It does not hibernate.
There is some contention among scientists as to whether snakes in Australia go into "hibernation" or not. Because there are few places in Australia that get really cold, most snakes go into a semi-dormant state. This means that they will still come out during winter if the weather warms up enough.Australia's winter months are June, July and August. Therefore, these are the months when snakes are less active through South Australia. Having said that, however, it is not uncommon for snakes to emerge from their inactive state in August, so is wise to be wary of snakes at all times anyway.
They hibernate in the winter when it is the coldest and food is scarce. Contrary to popular belief, not all bears go to sleep in the beginning of winter and emerge in the spring. Most bears will come out a few times during the winter but go back in to continue to hibernate.
Some well known mammals that hibernate are bears, bats and ground squirrels. Reptiles such as snakes, turtles and frogs also hibernate, but this differs from traditional hibernation because the metabolic processes are different. It is called brumation, and just means the reptile is less active, or slow. They still need to take in water and are not fully "sleeping". Hibernating slows down their bodily functions such as digestion and heartbeat, as well as their metabolism, or how they turn food and fats into energy so that they can go a whole season without eating. In order to prepare for this, the animal usually will gorge itself to build up a store of fats and eat fibrous things such as grass, tree bark, hair, etc., to for a plug in their bowels and prevent them from messing themselves during hibernation.
look up "brumate" on google, its close to hiberating but for lizards. They should also be eating, every few days
Yes, robins do flock together during certain times of the year, particularly during the winter months when they gather in large groups to roost and find food.
Because certain people believe in certain things...?
Raccoons have dense fur that helps keep them warm. During the coldest times they stay in their burrow and only emerge when conditions improve. They do not hibernate.

Yes, there were snakes in Pompeii during ancient times. The presence of snakes in the area is supported by archaeological findings and records of snake encounters in historical texts. However, there is no clear evidence to suggest that snakes were more prevalent in Pompeii compared to other regions in the ancient world.
