My wife and I parked on the side of the road leaning against the truck in the Chippewa national forest in northern Minnesota. In 30 minutes we saw the Blackburnian, Magnolia, Nashville, yellow, black-throated green, and yellow-rumped Warblers, a yellow bellied sapsucker, 12-15 red crossbills, American redstart, black-capper Chickadee and a pileated woodpecker. 5 or 6 others we could not identify. We nicknamed the location Warbler World. Very exciting for a couple of new birders.
