Interesting blue jay facts:
They are monogamous pairs that bond for life.
They are the provincial bird for Prince Edward Island.
The oldest known blue jay was a captive bird that lived 26 years. The common wild age is seven years, but one was recorded to have lived over 17 years through legbanding records.
Their feathers are not actually blue! The unique structure of their feathers reflect light and appear blue. If you were to crush a feather and damage that structure, the blue colour would disappear to brown.
Their love of acorns has earned them the credit of helping to plant oak trees after the last glacial period.
