Bird Behavior and Ecology in Glacial Regions

In summer, Swalot sees a migration of birds from the south. Reindeer and Tagan adapt to the season by changing their appearance. As ice melts, marine life becomes accessible, attracting blue whales. Little auks and thick-billed murres return to breed. Glaciers provide feeding grounds for seabirds, with meltwater supporting a rich ecosystem.
