* Hint: two of the warblers breed on the West Coast, and two breed on the East Coast; however, all migrated this fall to the Farallones (scroll to the bottom for answers).
Unfortunately, we were not able to go trick-or-treating since we are the only humans on the island. So instead, we admired our Jack-o-lanterns and enjoyed watching our favorite spooky movie, the Addam's Family.
Halloween Warblers, clockwise from top center: Magnolia, Black-throated Gray, Townsend's, and Cape May.
