A Yellow-crowned Night Heron was seen on the snag in the center of the Wetlands on Friday (5/27/11). To my knowledge this the first heron of this species seen at the Museum. It was probably on migration and was brought down by the severe thunderstorms of the day.
A Black-crowned Night Heron in immature plumage was seen in the Wetlands in May of 2008 and was in the area for a couple of days.
I would have gotten a photo of the yellow-crowned but it was very wet and, more importantly, a bolt of lightning struck directly behind us while we (Kristin, Sara, and three Museum Guests) watched the bird. Needless to say, we all scurried for cover.
