While out birding at the Jarvis Bird Sanctuary, @jbird56 and I heard the most amazing birdsong and couldn't identify it so we recorded it on our phones. When meeting a hard-core birder who knew much more than I did, we asked her to listen -- and she identified the song. Then last night when I uploaded my photos, it turns out that what I thought was a White-Crowned Sparrow is instead, THE singing White-Throated Sparrow. The yellow markings are the giveaway. Oh, so much to learn about birds.
Want to hear the song? https://www.youtube.com/watch?v=sL_YJC1SjHE
