This wild pet spawns in Winterspring but only during winter months.
Starts spawning: December 21
Stops spawning: March 20
Although it was first spotted November 1, 2012 and continued to spawn until March 1, 2013, Blizzard has since changed the spawning of this pet to correspond with the Northern Hemisphere real-world seasons. This means the Snowy Owl will begin spawning at the start of the winter solstice.
