"Sweet, sweet, sweet, sweet!" is the loud, ringing song that makes my heart leap. It brings me back to some of the most joyous times of my life... birding with friends along the north shore of Lake Erie in the middle of May. The little bird that carries the most weight with me is the prothonotary warbler. Perhaps it is the wet woods habitat or maybe rich, egg yellow color. It could be the nostalgia of those birding jaunts in Canada's "deep south" that makes my heart leap when I hear its song. - Robert Bateman
