Greater Snowbirds roam the mountain ranges stretching across the Isle of Xaaida. They mainly travel the mountains themselves, only descending to the forests surrounding the range during the spring. Greater Snowbirds live in small groups known as firns made up of 3-5 individuals, mainly made of a family. They are herbivores, browsing the rocky terrain for small shrubs, roots, and other hardy plant life. Despite being herbivores however, they are extremely dangerous. Greater Snowbirds are very territorial and protective of their firns, attacking any outsider snowbirds or most other creatures. Although their beak and claws are meant more for plants, their great size and antlers can seriously injure those they attack. Additionally, despite their size, they can move much faster than first appearances suggest, meaning a cautious distance should be maintained.

Instead of migrating during the winter, Greater Snowbirds roam the mountain range from summer to winter. Their pale feathers allow them to blend into the snow from a distance. During the spring, the birds will descend to the forests surrounding the mountains’ bases. This is when they mate, shedding their pale feathers for a brown coat for just this season. Greater Snowbirds lay 2 eggs at a time and are very protective of their nests. The birds build their nests within a shallow pit and one parent incubates the eggs while the other forages for food, the two taking turns. Névé are born at the end of summer, remaining in their firn until they find their own mate during the next spring and break off to form a new firn.
