During this morning’s heavy rain, I noticed a gutter overflowing. So as the rain was ending, I went out to clean it. When I finished, I heard the Carolina Wren start singing that showed up about a month ago in my yard on Bellingham in NE Rockford, and I became aware of lots of birds in the trees. In a few minutes, with my glasses constantly fogging over, I saw many migrant warblers, including Black-and-White, Chestnut-sided, Tennessee, Black-throated Green, Blackburnian, and Golden-winged. If you can get out between the coming downpours, the birding might be great.
