The Tolowa Dunes Stewards and Redwood Parks Conservancy are kicking off their 2018 summer nature program series Sunday with a celebration of International Migratory Bird Day.

Redwood Region Audubon Society president and guide Alexa DeJoannis will lead a birding tour starting at the Crescent City Harbor to scout for visiting seabirds. The trip will also include stops along the coast to search for shorebirds and inland to view songbirds.

The free tour starts at 8 a.m., meet behind the Chart Room in Crescent City Harbor.

This is the Tolowa Dunes Stewards’ 15th year of hosting specialized programs in Tolowa Dunes State Park, the Lake Earl Wildlife Area and Point St. George Heritage Area. Programs this year include a bike excursion through the Mill Creek Watershed, presentations on bees, Tolowa Dunes beavers, dune geology and elk monitoring, according to an organization press release.

There will also be several field trips, including a wildflower walk, a Lake Earl bike and hike, a Mill Creek watershed restoration tour and an excursion focused on Tolowa Dee-ni’ culture and history led by tribal member and linguist Loren Bommelyn.

The Tolowa Dunes Stewards are also seeking volunteers to help with bi-monthly restoration projects that focus on removing invasive European beach grass, according to the press release.

The next restoration day is 1 p.m.-4 p.m. Sunday will be Big Dune Restoration and Exploration.

Other agencies, groups and nonprofits sponsoring or providing leadership for programs include the National Park Service, California State Parks, Redwood National and State Parks, the U.S. Fish and Wildlife Service, Humboldt State University, the Redwood Region Audubon Society, Friends of the Dunes, Smith River Alliance and the Del Norte Trail Alliance.
