More Than 75 Million Birds Expected to Migrate Across the U.S. This Week as Spring Movement Intensifies From Texas to the Tennessee Valley
UNITED STATES — Spring migration is officially underway, and over the next three days more than 75 million birds are expected to move north across the country in one of the first major surges of the season.
According to migration forecasts for the night of March 2, 2026, roughly 21 million birds were already predicted to be in flight during a single evening, signaling the beginning of an active northward push. The movement appears to be happening slightly ahead of schedule, with hummingbirds already reported in portions of the Tennessee Valley region.
Strongest Migration From Texas Into the Southeast
Forecast maps show some of the highest migration intensity stretching from Texas across the Gulf Coast and into the Southeast, including Louisiana, Mississippi, Alabama and Georgia. Moderate to high movement is also visible through parts of Arkansas and Tennessee.
This corridor typically serves as a primary spring flyway, as birds move north from wintering grounds in Mexico, Central America and the Gulf region. Favorable winds and improving weather conditions often trigger these early-March migration pulses.
Farther north, migration activity remains lighter but is beginning to expand into portions of the Midwest and Mid-Atlantic.
Tennessee Valley Already Seeing Early Arrivals
Reports of hummingbirds in the Tennessee Valley suggest that some species are pushing north earlier than usual. March often marks the beginning of noticeable spring bird movement, but strong early-season surges can occur when temperatures moderate and storm systems align favorably.
The combination of lengthening daylight and warming air masses helps signal to migratory species that it is time to move toward breeding grounds farther north.
What This Means for Observers
With millions of birds traveling overnight, early mornings over the next several days could bring increased activity at backyard feeders, parks and wooded areas. Migration often peaks at night, with birds descending at dawn to rest and feed.
Residents across the Southeast, lower Mississippi Valley and parts of the southern Plains may notice new arrivals first, with activity gradually building farther north as March progresses.
While migration intensity varies day by day depending on weather systems and wind patterns, the current forecast confirms that spring bird movement is accelerating across the United States.
