- Spring migration sends billions of birds across the U.S. along four major flyways.
- See warblers, hummingbirds, cranes and more all around the U.S.
- Many prime migration hot spots are accessible and well-suited to travelers 50-plus.
You don’t need to be a serious birder with fancy binoculars or a life list of birds seen to appreciate spring migration. Each year, starting in mid-February, an estimated 3.5 billion birds cross into the United States from the tropics and South America along four major flyways.
If that sounds exciting to you, you’re not alone: An estimated 96 million people participate in bird-watching, according to the U.S. Fish and Wildlife Service. Of those, adults 65-plus make up the largest number of birders, at 23 million, followed by birders 55 to 64 at 19 million, according to the fish and wildlife agency. Most trips people 50 and older take are within the U.S., according to the AARP 2026 Travel Trends survey, so these destinations are well within reach.
Here are six spots around the country where spring migration puts on its greatest show.
Madrean Sky Islands, Arizona
Birders flock to this biodiverse corner of southeastern Arizona each spring, where the Madrean Sky Islands — isolated mountain ranges — rise from the desert floor, creating a rare convergence of desert and mountain habitats. “Southeastern Arizona is so special because of the geography,” says Vernie Aikins, administrative manager at Naturalist Journeys, a tour company that leads bird trips around the world. “We sit at the northern edge of the Sierra Madre Occidental, and birds, knowing no borders, stay within this range.” The result: a plethora of special species found nowhere else in the U.S.
The Chiricahua Mountains, one of the sky islands, anchor the tiny hamlet of Portal, a gateway to Cave Creek Canyon, often called “Arizona’s Yosemite” for its similar soaring rhyolite cliffs and rich wildlife. An ideal base camp, Cave Creek Ranch sits at 5,000 feet, with the surrounding Chiricahuas climbing above 9,700 feet. More than 370 species have been recorded in Cave Creek Canyon, and many can be spotted from shaded porches and feeders. Standouts include Rivoli’s hummingbirds and blue-throated mountain-gem hummingbirds, while higher up, red-faced warblers and Mexican chickadees patrol the pine forests, along with Mexican spotted owls. Night outings can turn up whiskered screech owls and elf owls, the world’s smallest, whose calls sound like a barking dog.
The Huachuca Mountains near Sierra Vista, widely considered the hummingbird capital of the U.S., offer another sky island experience. Stay at Casa de San Pedro, where professionals hold regular hummingbird banding sessions, placing tiny ID bands around the birds’ legs, recording health data and releasing them back into the wild. Nearby canyons are renowned for species such as the coppery-tailed trogon (previously called the elegant trogon) in the Ramsey Canyon Preserve, the flame-colored tanager in Miller Canyon and the Lucifer hummingbird in Ash Canyon. About an hour west of the Huachucas, the Paton Center for Hummingbirds is a go-to stop for the violet-crowned hummingbird, while closer to Tucson, the Santa Rita Mountains — home to Santa Rita Lodge and its feeders — feature many of the same birds.
