The Tolowa Dunes Stewards will kick off its summer nature series Sunday with a morning bird watching excursion starting at the Crescent City Harbor.

Led by wildlife biologist Craig Strong, highlights could include western grebe, common loon, black oystercatcher and pelagic cormorants, according to a Tolowa Dunes press release. The excursion commemorates World Migratory Bird Day in the Americas and will include a caravan from Whaler Island to Point St. George.

Participants will caravan in their own cars and are encouraged to bring snacks, drinking water, binoculars, bird books and spotting scopes if they have them.

The trip meets at 8:30 a.m. Sunday on the west side of the Chart Room restaurant, 130 Anchor Way in Crescent City.

Later in May will be a presentation on marine protected areas along the Northern California coast by Angela Edmunds, of California State Parks. Held May 26, Edmunds' presentation will focus on how the MPAs were formed and why they regulate human activity for habitat and conservation purposes. The program also includes a field trip.

Other nature programs this summer will include wildflower and lichen walks, tidepool exploration, a wetland safari for kids, dragonflies, beach rock identification, dune restoration and an auto tour into the Mill Creek Watershed. A special program by retired Humboldt State University professor Joseph Giovannetti will focus on the history and genocide of the Tolowa Dee-ni'.

The Tolowa Dunes Stewards' nature programs are a partnership with the National Park Service, California State Parks, the California Department of Fish and Wildlife and the U.S. Fish and Wildlife Service.

Most programs will take place 1 p.m. Sundays at the Lake Earl Wildlife Center, 2591 Old Mill Road in Crescent City unless otherwise noted. All programs are free, though some may require registration due to limited space.
