Nature photographer Eduardo del Solar’s primary goal is providing artistic and technical renditions of many species across the Americas. Join him on Sunday, November 7, from 2 – 3 at the Boston Nature Center, 500 Walk Hill Street in Mattapan, for a slide presentation documenting the migration of sandpipers from Mary’s Point, New Brunswick. In early August, the Bay of Fundy low tides expose the shrimp sources that allow these birds to double their weight and provide the fuel they need to take a non-stop flight to Central America. Come hear the fascinating story! Free. No registration required. To see the exhibit online, log on to http://delsolar.org/nature/webs/marypoint/index.html. Eduardo’s spectacular photographs will be on view through December 5 in the Boston Nature Center’s Education Wing.
