Judging from last year’s head count in the National Park System—a record 307.2 million—you can pretty much be assured that many parks will be even more crowded this summer as the National Park Service Centennial is celebrated.

I’ve talked at length about the best parks for birds and the parks where all the birders go. Everglades National Park usually tops that list. Big Bend and Acadia are also extremely popular birding parks. But which of the 59 national parks gets the least birding attention? That’s tough to quantify, but I’ve made an educated guess from perusing eBird data.

A website focusing on the history of the region that today encompasses Voyageurs National Park in Minnesota holds stories, photographs, and maps of the region to trace that past.

Four decades ago, on April 8, 1975, Voyageurs National Park was established as the country's 36th national park. This April, the nation celebrates Voyageurs’ 40th birthday. 2015 also marks the 50th anniversary of Voyageurs’ founding nonprofit partner, Voyageurs National Park Association. Together, the park and its partner will celebrate this anniversary and thank their many visitors, supporters, partners, and volunteers with a full year of special events.
