While most Floridians slept, more than 30 million migrating birds crossed the Sunshine State Sept. 28, as they made their way south to spend the winter in warmer climates.

According to birdcast.info:

• 1.5 million+ passed over Okeechobee County
• 2.2 million+ passed over Hendry County
• 1.9 million+ passed over Glades County
• 2 million+ passed over Palm Beach County
• 2 million+ passed over Lee County
• 3.7 million+ passed over Hillsborough County

What is migration, anyway?

In the Northern Hemisphere, migratory birds fly north in the spring in search of food and nesting habitat. In the fall, they fly south, retreating from the cold temperatures and food shortages that winter brings.

More than 450 North American bird species migrate from summer breeding areas — which may be as far away as the Arctic Circle — to overwinter in South Florida or the tropics. Some fly thousands of miles every year, instinctively retracing their ancestral routes.

“Fall migration is much longer than spring, as birds don’t move as quickly,” says Audubon’s Corkscrew Swamp Sanctuary Director (and avid birder) Keith Laakkonen. “In the spring, birds are driven to time their arrival with the food resources they need to raise their families, but in the fall, weather patterns have more influence on their movements,” he added.

How can you see them?

Head to local parks and natural areas, especially at dawn. Audubon’s Corkscrew Swamp Sanctuary in Naples is a great bet for birds on the move.

Lakkonnen explains: “Fall migration at the Sanctuary can be particularly good, especially since birds are usually moving at a slower pace than spring migration. Look for days when winds are lighter and have a southerly or westerly component, which can cause the birds to slow down and take a break. Add a little rain to the equation overnight, and you can have hundreds or even thousands of birds in our canopy here.”

How can you help them?

Support conservation lands.

Tell your local elected officials that you support city, county, and state conservation programs – like Florida Forever. Protected areas give these migrating birds plenty of space to rest as they make their impressive flights across the hemisphere.

Turn out the lights at night.

Most migrating birds navigate at night, and lights can disorient them. Turn out as many lights as possible during migration season.

Reduce window strikes.

During daylight hours, birds collide with reflective surfaces when they stop to feed or rest, when avoiding a predator, or flying from tree to tree. Shiny glass exteriors, internal plants near windows, glass corners, and greenery close to buildings can all be deadly as birds are unable to distinguish reflection from an open flyway. To reduce collisions:

• Create patterns on reflective glass surfaces (quantity and spacing matter: multiple markings 2 to 4 inches apart are recommended)
• Install external screens on windows
• Close blinds or curtains
• Move interior plants away from windows
• Place bird feeders directly on windows
