Billions of Birds Are Starting to Migrate South Through the U.S. Here’s How to Help the Birds Journeying Through Your Backyard

As autumn sweeps across the United States, it heralds a remarkable seasonal event—the mass migration of birds seeking warmer climates. Each year, an astonishing 4.7 billion birds leave the U.S. for the tropics, having traversed the Canadian landscape, contributing to a larger total of around 4 billion migrating south from Canada. This phenomenon, while a natural marvel, poses significant risks to many of these avian travellers.

According to research published in 2018 by ornithologist Adriaan Dokter, the migration involves millions of birds making their way south over a relatively short period. By late September, the state of Georgia alone is expected to see between 15 million and 20 million birds pass through, with an even larger influx anticipated in October. The sheer scale of the migration showcases both the resilience of these birds and the hazards they face along the way.

One of the most alarming threats to migratory birds is collision with buildings. Tragically, approximately 3.5 billion birds fall victim to these accidents each year in the U.S. Many birds are misled by the reflection of trees or sky on glass surfaces, mistaking it for open air. This issue, vividly highlighted by reports from National Geographic, underscores the urgency of developing strategies to make man-made environments safer for birds.

There are several practical measures that individuals can take to mitigate these hazards. Experts recommend switching off unnecessary indoor and outdoor lighting, particularly during peak migration times. Birds generally begin their journey shortly after sunset, a period when excessive lighting can disorient them. Additionally, closing blinds and curtains can reduce the risk of birds colliding with windows.

Furthermore, window safety can be enhanced through the use of visual markers. Adding decals, tape, or UV films in varied patterns can break the reflective surface of glass, making it more visible to passing birds. Such small adjustments can significantly contribute to the safety of these migrating species.

For those fortunate enough to maintain a garden, planting native flora that fruit or produces seeds in the autumn can provide essential nourishment for birds during their arduous travels. Maintaining clean bird feeders and birdbaths is equally important, as migratory birds can easily contract diseases when resources are contaminated—a situation that could prove fatal during such a high-energy period, as noted by Erika Zambello from Audubon Florida.

Pet owners can also play a crucial role in safeguarding birds by keeping cats and other pets indoors during migration season. It is well documented that free-roaming cats pose a serious threat to birds, particularly vulnerable species on their migratory paths.

In the event that a bird does collide with a window, there are specific protocols to follow to aid the injured animal. Using gloves, one should carefully pick up the bird and place it into a box or a paper bag that has air holes. It is vital not to offer food, water, or warmth, as these can be harmful to the bird. Instead, contacting wildlife authorities or organisations like Animal Help Now for further assistance is recommended.

Protecting migratory birds not only aids the creatures themselves but also enriches the experience for people, especially bird enthusiasts. With the autumn migration, a diverse array of species, including Cape May warblers, golden-winged warblers, and Connecticut warblers, becomes visible in areas where they might not typically be found. Nick Liadis, an avian conservation biologist, notes the remarkable variety of birds during this season, which many people might assume only flourish in untouched ecosystems.

As migration season unfolds each autumn, it is essential for communities to unite in protecting these remarkable birds. Through conscious efforts, we can ensure they not only survive their journey south but also continue to grace our landscapes for generations to come.
