RANCHO CORDOVA, Calif., Aug. 9, 2016 (GLOBE NEWSWIRE) -- Innovations in technology reveal that many migratory birds fly farther and faster and take more varied routes than previously thought. These findings reshape the conventional understanding of bird flyways—the notion that most birds migrate along four predictable corridors. According to a new report, they also reinforce the fact that billions of birds start their migration in North America's Boreal Forest. And they show that migratory birds depend on much bigger swaths of healthy landscape than experts realized.
Scientists tracked a Blackpoll Warbler—tiny enough to fit into a teacup—flying nonstop from the Canadian Boreal to the Caribbean. And they followed a Whimbrel moving from its breeding grounds in the Mackenzie River Delta on to Hudson Bay and Cape Breton Island before making a nonstop flight to Brazil, covering more ground in the Boreal Forest than previously documented.
"Birds go farther and faster and have broader migratory routes than we thought. This new evidence shifts our understanding of what migratory birds need. They need landscapes to remain wild on a much larger scale," said Dr. Jeff Wells of the Boreal Songbird Initiative. "That opportunity still exists in North America's Boreal Forest—the nesting ground for billions of migratory birds."
These discoveries, outlined in the report Charting a Healthy Future for North America's Birds, emerge as Canada and the United States celebrate the 100th anniversary of the Migratory Bird Convention this August. The treaty helped numerous bird species rebound from near extinction, but now many species are in steep decline and face grave new threats, ranging from climate change to habitat loss.
In June, Prime Minister Justin Trudeau, President Barack Obama, and President Enrique Peña Nieto renewed their nations' commitment to protecting migratory bird habitat and called for developing a vision for the next 100 years of bird conservation.
The report, released by the Boreal Songbird Initiative, Cornell Lab of Ornithology, Ducks Unlimited, and Environment for the Americas, offers a 21st century approach to sustaining migratory birds. It calls for protecting at least half of the Boreal Forest and honoring the rights of Indigenous people—often the frontline stewards of bird ranges within the Boreal Forest—to conserve their traditional lands.
"The Migratory Bird Convention was critical in saving numerous species from potential extinction 100 years ago, but it's time for another breakthrough. Raising the targets for how much habitat we protect—particularly the call to protect at least half of the Boreal Forest, the breeding grounds for billions of migratory birds—could be this century's great conservation idea," said Dr. Frederic Reid of Ducks Unlimited.
The findings in the report strengthen the scientific consensus around large-scale conservation:
Satellite tracking and geolocator technologies are providing detailed accounts of when and where birds move, revealing critical areas of migratory habitat for potential protection.
Radar and audio sorting technologies paint new pictures of nocturnal migration, including discovery of previously unknown rest stops that songbirds rely on during migration.
And citizen scientists uploading observations via mobile phones have helped chart the full migration cycle for 118 species, demonstrating many species' reliance on the Boreal Forest.
"These technologies confirm that protecting the Boreal Forest will deliver continental-scale benefits for billions of birds and the ecosystems they support across North America," said Dr. John Fitzpatrick of the Cornell Lab of Ornithology.
