Here's what happened last night...

Birds in flight

Birds usually begin to migrate 30 to 45 minutes after sunset, with the greatest number in flight two to three hours later.

Flight direction and speed

Birds tend to migrate southward in autumn, but seasonal timing, weather, and geography alter their flight directions and speeds.

Altitude

Migrating birds regularly fly up to 10,000 feet above ground, although seasonal timing and weather conditions dramatically impact their distributions.

Note: Direction, speed, and altitude may be unreliable when the number of birds in flight is low. In such cases, chart data may include gaps.

And so far this season...

Birds in flight (nightly avg.)

During fall migration, most birds pass through the contiguous U.S. from early September through October.
