I heard 10 BTBs saturday, May 17 on the western slope and top of Moose Mtn in Cook County. This site and Tettegouche Park are clearly the places with the largest numbers of this warbler. In both places one must hike to find the birds; I had a six mile round-trip on saturday, starting at the Oberg Mtn parking lot. I had none at Oberg, but I did not climb Oberg. I have never been on this section so early, and this is clearly the most I have heard so early in the season anywhere. Also, many BTgreens, ovenbirds, nashvilles. Some blackburnians, parulas, RB grosbeaks. Maybe one vireo, no mournings, canadas, they are later. Also, about 100 runners, happy, pleasant and not interfering with my listening, but a large number of people on the trail. No other hikers.
