Globe-trotting nature adventure photographer Galen Rowell once wrote of his pleasure in maturity of experiencing nature close to home. He illustrated his essay with an image from Berkeley’s Aquatic Park, an estuary divided from San Francisco Bay by I-80 on the west. On the park’s eastern border 200 yards away run long-haul railroad tracks.
The tidal estuary connects to the bay, bringing shellfish to herons, egrets, pelicans and migrating avians of all types. In the last several days, Monarch Butterflies have chosen to stop in the park and rest in a tree. Access to water, sheltering trees, cold and fog make it ideal habitat for the “milkweed butterfly” (Danaus plexippus).
Thanks to Elena Miller Bond for her article in Berkeleyside that provided notice of this rare and beautiful sight. http://www.berkeleyside.com/2015/11/23/first-time-observed-hundreds-of-monarch-butterflies-cluster-in-berkeleys-aquatic-park/.
