This article by Paul Bogard, Spring 2021, discusses the billions of birds that fly north in the spring, some on an 8,000 mile trek. Imagine.
Many fly in the dark, which most of us who belong to the forestry boards, already know.
Habitat destruction, collisions with buildings, declines in insect abundance—the threats to migrants are many, and the question has become: Can new tracking technologies help to unravel the mysteries of nocturnal migration while we still have time to preserve one of the world’s great natural wonders?
This is a time fraught with danger for migrating birds. The impact of climate change resulted in that the “peak migration in spring and fall came sooner and coincided with higher temperatures in the continental United States.” This disruption puts the migrants increasingly at risk, such as the lights of skyscrapers at night that confuse migrating birds, disorienting them, and causing their collisions with the buildings, killing them in billions of numbers.
Bogard’s is a detailed article well worth reading for those of us who consider how climate change affects our bird species and mother earth.
If you have not watched “Winged Migration,” a film produced in 2001, it is breathtaking. It made my heart soar. The film, which covers bird migration all over the world, is more than ten times longer than this preview.
You can rent the film online for a pittance if you have not seen it before.
Here’s the French Trailer with different scenes:
