How the Hummingbird Migration Will Sweep Across the Southeast
Sep 15, 2025
Every year, one of nature’s most extraordinary journeys takes place in the skies above us: the hummingbird migration. Despite their tiny stature, these birds undertake a breathtaking voyage that can stretch hundreds or even thousands of miles. And this year’s migration is already proving to be just as remarkable as ever.
When it’s Happening
Hummingbirds typically begin their southbound migration in late summer and early fall, with the exact timing depending on the species and where they start. In 2025, sightings of ruby-throated hummingbirds have been recorded as early as August across the northern states, with peak movements occurring through September in the southeast, including right here in Tennessee.
Why They Migrate
Like other birds that fly south for the winter, hummingbirds migrate to follow the food. As flowers fade and insect populations decline in cooler northern climates, these birds head south in search of nectar-rich blooms and warmer weather. Their internal clocks, daylight length, and even changes in food supply all help trigger the instinct to move.
What’s Different This Year
Reports from birdwatchers and tracking projects suggest that this fall’s migration may be slightly earlier than average.
Many enthusiasts are noting stronger numbers at feeders, a good sign that populations remain healthy.
However, an extreme weather event, like hurricanes in the Gulf of Mexico, are something to keep an eye on, as they can create difficult barriers for migrating flocks.
How You Can Help the Hummingbirds
Your participation can play a big role in conservation science.
You can help by reporting sightings to eBird or Journey North, which will help researchers track migration timing and population health.
Keep feeders up into late fall.
Hummingbirds may pass through your area weeks after the “usual” peak.
You can provide natural food. Native flowering plants like trumpet vine, cardinal flower, and salvia extend nectar sources beyond artificial feeders.
What You Can Get at Co-op
Many Co-ops carry bird feed and other supplies to attract hummingbirds so you can get a view for yourself. Head to the Co-op nearest you, and let us help.
