September 1962.

Perk moves down the stairs, coffee steaming from the cup in his hand. He wears a black peacoat adorned with two vertical rows of gold buttons and matching cuff stripes – the officer jacket of the Pittsburgh Steamship Division. He stops briefly near the bottom stair to sip the hot liquid down away from the cup’s lip, lest he spill in his eagerness to witness what he had predicted would happen this night.

Upon opening the heavy metal door, Perk is met with the thick cold scent of wet iron and lake. He squints into the lights illuminating the cargo deck as his eyes adjust to the freighter’s glow in Lake Superior’s dark freshwater sea.

“Captain Perk,” the watchman yells, “watch your step. Many are still alive!”

September 2009.

When I met Captain J. P. “Perk” Perkins, he was a black and white figure near the center crease of a sixty-year-old magazine. It had been over a week since I’d witnessed something that my mentors and colleagues at first dubbed a product of a vivid imagination. At an overlook near the coast, tens of thousands of warblers, thrushes, grosbeaks, sparrows, and other songbirds filled the air above and around me, while the sun rose over Lake Superior. The morning flight of migratory birds — disappeared just as quickly as it began. I told anyone who would listen.

Sometime later an old magazine ended up on my desk with a note from a friend, You should read this. By then, the captain had been gone for 20 years.

The fog had changed to a misty drizzle. When I aimed the searchlight upward, the beam revealed heavy flights of passing birds. Others fluttered around the ship’s lights by the dozen. At times there were so many on the bridge deck that the lookout had to be careful not to step on them.

Challenge: A migration phenomenon under threat

Every fall 90% of North America’s boreal forest biodiversity takes to the sky in one of the world’s largest natural phenomena — the boreal bird migration. But in the past 50 years, North America has lost 2.9 billion birds — one-third of the avian population. Most of those lost are migratory birds. Of the 5 billion birds that migrate south in the fall, more than one-third will not survive to return in the spring. Human caused threats throughout this journey compound already high levels of natural mortality.

During fall migration, billions of birds travel on a movement trajectory that guides them towards the U.S. Great Lakes region. Ten percent of the U.S. population (over thirty million people) live within the watersheds of the Great Lakes. This includes the metropolitan areas of Chicago, Milwaukee, Cleveland, and Detroit, and the cities of Duluth, Green Bay, and Buffalo. These same coastal areas host disproportionally large concentrations of birds during migration. Impacts from the most dangerous human-centric threats to birds — including habitat loss, predators, pesticides, and collisions with manmade structures such as buildings, communication towers, wind turbines, and power lines — are intensified in these populated coastal regions.

A CONTINENTAL PHENOMENON. Every fall, five billion birds migrate out of N. America’s boreal forest to areas as far south as South America. Avoiding the prairies and guided by NW winds, many migrate to and through the U.S. Great Lakes region.

ATTRACTED TO COASTAL GLOW. Nocturnally migrating birds are drawn to artificial light and disproportionately concentrate their movements and stops within Great Lakes coastal cities. Within these ‘light halos,’ mortality caused by collisions with structures and predation by house cats is intensified.

An Ore Ship Captain and His Onboard Forest

SHELTERING IN A FREIGHTER’S FOREST. In 1958, after years of photographing the migratory birds that landed on his ships to rest during migration, Captain J.P. Perkins (pictured) created a mini-forest of potted trees for the feathered castaways. Image: J.P. Perkins / U.S. Steel.

From 1928 to 1972, Captain J. P. “Perk” Perkins sailed the U.S. Great Lakes onboard freighters that carried ore and other cargo between Lake Superior and Lake Erie. Perk had a unique passion for birds. For the majority of his life as a mariner, Perk recorded the migratory birds that sought shelter on his ships, including a cobbled assemblage of potted trees he set on freighter’s deck that the crew named Perk’s National Forest.

After decades of sailing the Great Lakes, Captain Perkins could predict when his freighter would enter any one of 17 different flight corridors that hosted massive numbers of migrating birds. He documented and told stories of his bird migration observations through a film production he called Birds Ahoy. He also produced a hand-drawn corridor map to educate the public and scientific community about these over water movement corridors.

In my long career, I have worked on hundreds of research projects. The story of Captain Perkins is one of the most personally compelling. Not only is it an early and valuable example of citizen science, but the captain’s story itself is captivating. NatureWerks threads migration science and his legacy with grace.

Captain Perkins Project

This project seeks to tell Captain Perkins’ story to foster awareness, research, love, and protection for the bird migration phenomenon he sought to understand and the story that he worked to tell.

Strategy

Outcomes

Historical ecology. Preserve, archive, and restore Captain Perkins voluminous records, including avian data, journal entries, artwork, photos, and film.

Mapping Migration. Identify important bird movement areas both on and offshore in habitat and airspace. Compare new data with maps Captain Perkins drafted 60 years ago. This includes emerging techniques being advanced by ornithologists coupled with citizen science observations by regional bird lovers. Use this information to inform conservation and thoughtful development.

Human interest. Bring the story of Great Lakes bird migration to life through art, media, science, and creative writing. Build pride campaigns to observe, teach, and share this beautiful phenomenon under threat throughout the Great Lakes region.

Traveling Multimedia. Help people see the beauty and resilience of birds migrating through their home towns through a mobile multimedia art and human interest exhibit that will be coupled with regional events in cities and towns throughout the Great Lakes region.
