The Canada Jay is a true Canadian bird and doesn't migrate south like many other fair weather birds. They store their food in the bark of spruce trees where it becomes encased in tree sap. They begin their nesting remarkably early during late winter. It's for these reasons, and many others, that I have become quite fond of these birds. Unfortunately climate change is having a dramatic impact on their habitat. With warmer winters, their food caches are not lasting the long winter months and as such their range is slowly declining.
