Chet Meyers writes: Just returned from five idyllic days on the north shore of Lake Superior in Cook County. Miriam and I hiked the Oberg Loop just off the Superior Hiking Trail a few miles from Lutsen resort. Last year we found five male black-throated blue warblers singing on territory and this year found six. To get to the Oberg Loop take highway 61 along the north shore and between mile markers 87 and 88 turn north on Onion River Road, also highway 336. Follow it until it ends, park in the parking lot, and walk to the trail head. Follow signs to the Oberg Loop which is considered a trunk loop of the Superior Hiking Trail. The entire hike up and back took us an hour and fifty minutes, however, we found one singing male less than a quarter mile in. But don't expect the birds to sound like those on the Stokes bird tape. Indeed, they sound like a cross between black-throated blues and black-throated greens. Only one bird we found sounded like the normal black-throated blue song (whatever that is). Chet Meyers
