{{{ Perching Blackpoll Warbler }}}
The sharply marked blackpoll warbler is nature's hearing test, with a high-pitched, almost inaudible song. This long-distance athlete weighs less than half an ounce yet makes the longest overwinter journey of any songbird - nearly 1,800 miles nonstop over the Atlantic Ocean to its wintering grounds. In the fall, this black-and-white warbler molts into yellow-green plumage and loses its black cap. Imaged 17 May 2022 in central Minnesota.
