The Canada Jay should probably be one of our national symbols. Found everywhere, from coast to coast and north to south, they are extremely prolific.
Many people love them while others find them extremely annoying. They are very opportunistic omnivores (basically, they will eat almost anything), but I have never found them to be particularly aggressive. In my experience, they will sit at the end of the picnic table, patiently waiting for leftovers or handouts, and quietly chirping to remind you not to forget them.
Smart and adaptive, they are one of the few examples of Canadian wildlife to retain their original indigenous name: Wisakedjàk (Algonquin) which then became “whiskey jack,” as they are often called. Indigenous peoples consider Wisakedjàk to be a trickster, which considering the jay’s behaviour, is very appropriate! Although they are related to crows and ravens, they are also categorised as songbirds, an interesting distinction.
Here is an example of their song. https://youtu.be/zEvBatYBwbo
