Harris's Sparrows only pass through Duluth in the spring and fall. Their summers are spent in far northern Canada in the Northwest Territories and Nunavut, thereabouts. In the winter, they fly south, generally to Texas, Oklahoma, Kansas and Nebraska.
It is always thrilling to see migrants, especially this one, one of my favorite sparrows. I have not seen them yet this spring, but they are due here anytime now. It's possible Wednesday's record snowfall set them back a couple of days. This particular bird was seen exactly one year ago to the date.
I hope you can get out and spot some migrants this spring.
