Despite being equines, pegasi resemble birds in behavior. They produce a large variety of sounds, and are very chatty creatures. Highly social, they developed a way of communicating through long distances - whistling. The whistling language can only be produced by pegasi (and noctules who learned it from them), but can be understood by other species if they were exposed to it enough (though they will not be able to produce it).
Pegasi are quite skittish and naturally avoid confrontation, prefering to take flight when they feel threatened - it is not their first instinct to fight, but the latest events in the Crater and the sudden disparition of the unicorns made them considerably more aggressive towards their predators (kelpies and noctules). They are curious creatures, and will often investigate anything new they encounter - pegasi are known to be very thirsty for knowledge that can lead them to new discoveries.
The bird horses are mostly nocturnal creatures, and will therefore be more active at night and at the twilight hours. They can see very well in the dark, and their black sclera helps a lot with the strong lights that can occur in the clouds or snow, but their sense of smell is not the best. Being very good at flying thanks to their three-segmented wings and their light weight for such big creatures, their agility is remarkable and makes them efficient predators to small prey (rabbits, birds, rodents...). They are attracted to the stormy skies, and will often be seen flying during thunderstorms, "playing" with the lightning and strong winds. Pegasi are able to know where the lightning is about to strike some seconds before it does, an ability that is very useful in their prefered environment, the snowy mountains.

Body language is an important part of their communication, as they can express a lot of emotions through their wings, tails and head crests. Their head wings are very sensitive, providing them very effificent hearing. Omnivorous, these equines will eat a lot of different things, from plants to small animals, including fruits, seeds, roots, insects. Pegasi are very careful of their plumage, and will spend a lot of time cleaning and oiling their feathers to keep their abilities at their best- they naturally produce oil, but can use various products to improve it.

When pegasi reaches maturity (around fifteen years, the equivalent of twenties for humans), they might start looking for a partner (or not... it's a posibility). Pegasus courtship is similar to birds, expect the male AND the female will perform for eachother, and will both try to impress the other with their flying and more specifically dancing skills. An interested mate will return the other's advances and gifts, and all of this will eventually lead to a strong bond betwteen the two.
Pegasi couple will usually have one foal at a time- as they are equines, foals are born the same way as horses, and DO NOT hatch from eggs. Newborn foals are very small and fragile, covered in down and unable to stand up. They will be kept in a nest made of feathers and other soft materials, and will require the mother's milk to survive, but will be introduced to solid food very quickly after their birth. The whole clan takes care of the foals, males and females alike, especially the nurses who work full time to take care of the newborns in the nursery, ensuring the temperature is right and all the foals are fed and healthy. This way, parents can take care of themselves and keep serving the clan.
When a foal is ready to walk, the nurses will keep teaching them the basics, and will join their parents' nests and leave the nursery.


Sadly, it can happen that a foal is orphan, and when this is the case, the nurses will take care of them until they are adopted by a new couple, or a solo parent. This is very common for them to adopt orphan foals.

Young pegasi will experience a complete molt around the age of 1-2 years, and will lose all their down to grow their adult feathers. This phenomenon can reveal new colors and patterns, which can be drastically different from the foal's original appearance. The molt will be repeated every year, but will be less drastic and almost unnoticeable as only the damaged feathers will be replaced. After the first molt is completed, the foal will naturally start to jump and use their wings. With the help of their parents, they will eventually learn to fly, and will have to practice to be able to pass the "first dive", a flight evaluation that will permit them to access school and higher lessons. A pegasus is considered adult at the age of fifteen years.

Pegasi are social creatures, and have a hierarchy as well as a ranking system that they shared with unicorns. Each member of the clan is important and pegasi are devoted to their community.

Before the unicorn's extinction, there were numerous clans all over the world. Pegasi built their homes in the mountains, to avoid the disturbance from humans and their natural predators. Today, as the unicorns are extinct and the world is changing to become more and more welcoming to creatures, pegasi gather together inside the Crater to protect themselves, joining the clan that birthed the latest Vicereine, Heimdall. They know they are stronger when they are united, and being close to the Vicereine makes them feel safer.

All clans have a main home, the Nest as they call it, which is most of the time located in a high place such as mountains. All Nests are different, but they contain similar rooms and areas, such as the nursery, the conference room, the infirmary, the announcement pedestal, and pegasi personal homes.

Pegasi's Nests are very well organized, every single member of the clan has a role to play and makes sure everything is well kept. The higher ranks don't even have to give the orders to forage, as the lower ranks know what to do and will do it without receiving orders. Their community instinct is very strong and a pegasus need to feel important to the clan. If one individual has a problem, the others will naturally help with it.

Pegasi have their personal homes in the Nest where they can rest and stock their personal belongings. Usually these homes are built in the walls of the mountains. The higher ranks have bigger appartments inside the mountains, usually quite close to the conference room. At the time of the separated clans, the Viceroy had a place to stay in each Nest, even if he was not there most of the time, it was an important thing to keep the room ready for their visit.

All Nests have a cemetary near - still located very high to avoid scavengers, as pegasi don't bury their dead. The reason behind this is because of the Moon - when a pegasus or a unicorn dies, it is believed that the Moon will welcome their souls, therefore hiding a body under the ground would be hiding them to the eyes of her Majesty of the Night. Cemetaries are mostly gravestones (without writtings on it, as pegasi do not have a written langage), with skulls and decaying bodies facing the skies.
The dead ones' relatives will often visit them, bringing flowers and pretty things to them to honor their memory.
In death, all pegasi and unicorns are the same, regardless the rank they had during their lives - even the higher ranks are buried like the other members of the clans. Once one individual dies, it is believed the Moon will grant them a new existence in the clan. It is no secret that the cemetary of the Nest has a lot of unicorns as of their recent extinction, but many unicorn remains are still visible all over the world and the Crater...

Pegasi and unicorns have a strong connection with the Moon - to them, the Moon is some sort of deity that have great influence over their lives and their way of thinking their world. Whether this is true or not is unknown, but most pegasi believe in the what they call "her Majesty of the Night".

The Viceroy is the incarnation and living representative of the Moon, which is why they have the highest rank in the pegasi hierarchy - the Moon is considered to be the real sovereign of pegasi, just above the mortal Viceroy. The Nests are built on mountains to be close to the Moon.

Most of the rituals, ceremonies and clan decisions are made by asking the Moon's will, which is the Enchanters' duty. Pegasi will often pray to the celestial body, and thanking it for the good things that are happening to them or the clan. The Moon is also one of the reason pegasi and unicorns are more active at night.

Pegasi and unicorns were known to live together, in a symbiotic relationship. Both species found advantages by staying which each other - this ancient relationship led to a very strong connection between the two species, who were living together for millennia until the dissappearance of unicorns.

Unicorns were very protective of pegasi. Their natural strength and their ability to fight kelpies and noctules were essential to the pegasi' survival. In exchange, the pegasi offered all their knowledge and comfort to the unicorns.
Heimdall's existence shows that unicorns and pegasi could mix and have offsprings. Hybrids remained rare during their history, but unicorn and pegasus couples were very common. Since the unicorn extinction, pegasi are actively carrying the memory of the unicorns through murals and such. But they are never talking about what caused their extinction. It seems to be something the adult never talks about, so the young pegasi don't even know what happened to them.

Pegasi are mistrustful by nature. They are prey to bigger creatures, like noctules and kelpies, and will not stand a chance if caught due to their size and very light bodies.

Pegasi are scared of kelpies and are actively trying to locate kelpies nests in the Crater. They are calling them "water demons", referencing the natural aquatic environment of kelpies, and their dangerous nature. They seem to be very cautious of the adults, but the guards have orders to kill any kelpie foal they could encounter if it's possible.
It is pretty much the same with noctules, and are calling them "shadow demons". Noctules are known to get much closer to pegasi's Nest than other predators. They can imitate the whistle language perfectly - not to mention pegasus are very easy prey to them. The cervid creatures are talented to learn pegasi sounds and voices, and are reputed to try luring the bird horses out of the Nest, which is why there's a lot of pegasus sentinels all around the Nest.

Recently, pegasi have been seen interacting more aggressively with "demons", and have developed special apparel to avoid injuries in fights. It seems they have decided to fight instead of fleeing. Not all pegasi agree with this thinking - some want to leave the "demons" alone, some think they are equal to pegasi.
