Yes!
I'm happy to report I saw a crow sweep in for the peanuts on our back deck well before the jays arrived this morning. In fact, I didn't see or hear any jays. But I would be amazed if they never showed up.
We have similar levels of snow. I'm in northern Wisconsin. I'm never sure exactly what counts as northern Ontario. I tend to assume that means north of the Trans Canada Highway but that's my personal definition that may not reflect anyone else's usage.
