Orange-crowned warbler is listed as very rare in the Sherwood Island checklist, but in mid November of 2009 we were lucky enough to have three of them in the park for a few days. They spent their days eating the beautiful but highly invasive porcelain berries now blanketing scattered sections of Sherwood. This one, and one of the others, frequented the area of the little footbridge in the vicinity of the Nature Center. The Orange-crowned Warbler’s best field mark is that it has no obvious field marks. It’s a very plain little warbler and its nearly mythical orange crown is rarely seen.
