The fog cleared to several miles of visibility yesterday. When that happened, a bunch of birds dropped in to the Island. Best birds: Red-throated Pipit, Yellow-green Vireo, Black-throated Blue Warbler, and Chestnut-collared Longspur. The Summer Tanager continued, as did some Tennesse Warblers. I went up and slept at the lighthouse, in case of massive fallout this morning. Sadly, life was pain. Visibility was too far (I could see SF when I woke up) and all I saw were a Violet-green and some Waxwings.
