During the winter months up north, the cold, icy territories that these dragons live in grow much too chilly for them, too. Thus, they fly further south, seeking out something more comfortable. However, once arriving upon their chosen land, they find the territories to be too warm, and use their magic to chill the territories and bring ice and snow that they are accustom to, only to leave when it's not quite comfortable enough. 

Withbreath Dragons form large flocks with a queen to lead them, who leads until they grow impossibly massive and old, eventually falling from the skies in their flight and dying. The oldest juvenile female in the flock then takes the old queen's position, commanding all dragons within the flock. Interestingly, there never seems to be any form of fighting for dominance within Wiltbreath Dragon flocks- they are matriarchal, with the highest respect going to the oldest females. The youngest males of the flocks are the lowest on the rung, often being sent to hunt and fight for the rest of their flock. However, female Wiltbreath Dragons, with the exception of the Queen's immediate family, are kicked out of the flocks after they have reached old age. Here, they become queens and start their own flocks. Once a year, Wiltbreath Dragon flocks loosely dissipate as they search to find mates. After their courtship, the two dragons engage in battle. Whichever dragon wins determines which flock they return to.

Although the Wiltbreath Dragons reside in all the territories when they pay visits to the Great Valley, CoveyClan and TideClan are favorite spots to play in. Juvenile dragons can be taken down by large groups of determined cats, but their icy breath is lethal.
