San Francisco Nature Education is a non-profit run by naturalist Nancy DeStefanis to show a little bit of nature to city dwellers. On their calendar this Saturday at 10:00 AM is another day of observing wildlife near the Stow Lake boathouse in Golden Gate Park. Experts will be stationed at the observation site with spotting scopes ready to offer views into great blue heron nests, and there’s a nature walk as well. We should have good weather, so check it out, right h’yuh.
