One of our most common warblers in the Northeast, lovely Dendroica magnolia was named by ornithologist Alexander Wilson after collecting a speicmen out of a magnolia tree along the Mississippi in 1810. He initially used "Magnolia" for the latin name, and "Black and Yellow" warbler for the English, so obviously this got changed at some point. They are fairly conspicuous as they forage near the ground. Males have black and yellow patterning on the face, whereas the females lack some of that bold patterning. Unfortunately, it seems as though I have seen many come through the lab at the museum. I have seen Dr. Willard preparing them, and even someone of his experience still seems stunned by their beauty everytime.
