Common Goldeneye are common winter residents around the Great Lakes, and in fact all across southern Canada. They nest further north than here though, in the boreal forest, where they seek out cavities in trees for their nests. So they are common here from October until April, and then largely disappear. When they go 'south' for the winter, they only come this far, to enjoy the ice and snow!
I have re-activated my account with 'ebird Canada', a large database of electronic records of bird sightings. In fact you can look up the records without having an account at all. It tells me the seasonal pattern of bird sightings for my own county, and provides a map too. I used to be fairly active as a birder, if never very good, and after Wednesday's incorrect identification of birds on my own blog, I'm inspired to get back into this a little - I need at least to get the ID right if I'm going to post bird pictures!. We'll see if I find any interesting birds over the summer.
