During the rainy season, Star Gliders stick within their small pods of 2-8 individuals. These pods are often bonded pairs, but lone females may group together. Bull Star Gliders typically stick to themselves while searching for a mate, but may form pairs or trios with other males. They bond for life, but don't care for their offspring. During the breeding season, taking place between February and early April, they lay their eggs in shallow waters and leave their young to care for themselves. They only reproduce every 5 years, and out of the hundred eggs they lay, only a couple will live long enough to  leave the water. They congregate in groups up to the hundreds in this time, often visible in the horizon from Clan territory. As the dry season begins, they migrate out of Clan territory and soar above the open ocean until the rains return.

Young Star Gliders are bound to the sea, unable to fly for the first 17 years of life. In this time, they inhabit coastal waters, feeding on ambient magic and plankton. During the rainy season, they breach often, continuing this behavior until their wings catch the air, where they'll live for the rest of their lives. The only return to the water to mate and lay eggs, but it's not uncommon to see sick and dying Star Gliders return to the sea. They only feed on ambient magic during adulthood, but will consume clouds for their water vapor, occasionally catching smaller flying creatures. They have incredibly long lifespans, and can reach ages of 600 years.

Star Gliders are indifferent to other creatures that do not pose immediate threats to them, and will even ignore known predators when young. When threats do present themselves they are known to flee rather than fight, but they will defend themselves when faced with no other option. They can produce sounds as loud as 270 decibels, loud enough to harm other creatures. They have incredible memories, and can recognize cats who have been kind or aggressive towards them before.
