The Common Yellowthroat is a new world warbler and a summer resident of the bog. I am very familiar with this bird, and yet, every fall I spot a juvenile frolicking with the migratory warblers and I get very excited. At long last I have discovered a new warbler species! Wait a minute… is that? It is, GRRR!!! It’s just a mischievous little juvenile yellowthroat! Oh well, cute bird though.
