Canada Jay female incubating

Canada Jays begin building nests between mid-February and mid-March and females incubate eggs in sub-zero temperatures, often during severe snowstorms. What is remarkable is that females rely almost exclusively on cached food during this time because there is little fresh food available during the depths of winter. To top it off, males rarely feed females while they are  incubating, likely because they want to minimize activity around the nest so as not to attract predators.
