Yesterday and today the Arctic arrived in northern Minnesota! I saw Lapland Longspurs, Horned Larks and my first Rough-Legged Hawk of the season. The birds were split between Two Harbors (the songbirds) and Sax-Zim Bog (the hawk). The numbers are not yet huge, but they’ve flown quite a distance!
This map is from Cornell’s All About Birds. All 3 species could use the same range map (some horned larks also breed further south)
Just a quick post. Sparrows are appearing in fantastic numbers in my yard, including this Harris Sparrow. Very few of the sparrows use my feeders, but they love sloppy seconds. They breed up on the tundra. 
And to give equal time to a more common bird … Slate Colored Junco.
We are starting to get near the end of the songbird migration. When the snow buntings appear I consider the songbird migration over.
I’ve been meaning to post this information for some time, but now as we head towards winter the recommendations are more important. If you like to bird remote, dirt roads MAKE CERTAIN you have local knowledge, or keep your excursions on dirt roads which have “metal country road number signs”. 
Google Maps will get you into situations that are expensive, it not dangerous. If Google Maps suggests an alternative route, be wary in the road is not paved. Most dirt roads have never been mapped out “in person” by Google, and quite often Google Maps decides an ATV (all terrain vehicle) trail is actually a road. Here is an image I took recently while birding Stony River Forest Road about 40 miles north of Two Harbors. Please note the following:
While I talked about restricting your travels to dirt roads which have “county number metal road signs”, avoid any road “like the plague” that has a sign like this one (minimum maintenance road)!
While roads of this nature can be fine, you really need local knowledge. If these roads are snow covered or wet / mucky, the danger multiplies. I actually prefer to first hike unknown roads. Hiking is how I discovered the “rock pile parking spot” 6/10 of mile from Lake County Two on US Forest Road #813 near the Greenwood Creek Bird Feeders which I maintain.
Another road to avoid as we head towards winter is the “cross-over dirt road” between Admiral and McDavitt Roads in Sax-Zim Bog. While this road is fine is good weather, it is not plowed in the winter and if you get stuck a tow will cost over $1,000. This assumes the tow truck driver is willing to venture onto this road. You will also likely have to wait for hours for a tow truck to arrive.
My final words of advice, in winter a car in northern Minnesota or other remote areas should be an “all wheel drive” car. Obviously 4-Wheel drive is even better. Before you think this advice only applies to northern Minnesota, if you like to bird and drive dirt roads in the countryside within 60 miles of a large metro area (like the Twin Cities), these problems can also happen to you!
