Identification

 

A large songbird with its distinguishing blue colour on the back, head and tail. Black and white also appear in lesser amounts on the upper surfaces and the underparts are white. They have a feathered crest atop the head and males and females are very hard to tell apart.  They make a variety of sounds but the most common is a loud "jeer".

 

 


Interesting Facts

One of their favorite foods is acorns and it is thought that they are a large reason for the spread of Oak trees after the last glacial period.

Blue pigment is unknown in birds so the striking colour we see in the feathers is actually a refraction or distortion of light by the inner structure of the feather.

They have been known to grab ants with their beaks and rub them onto the surface of their feathers. This is called "Anting". This happens most often during moulting and it is thought that perhaps the process of changing feathers irritates the skin and the ants contain a form of soothing material.


Blue Jays on the Niagara Escarpment

These birds are present year-round along the entire length of the trail. Look for a flash of blue as you hike the trail or listen for their loud calls and chattering. The Bruce Trail Conservancy is continually acquiring and protecting forests and wooded areas along the Niagara Escarpment providing perfect habitat for these birds during their entire life.
