As temperatures rise, hummingbirds begin their migration to the United States, arriving along the Gulf Coast in early March and gradually spreading across dozens of states. After spending the colder months in Central America or Mexico, the beautiful birds are a welcomed sight with the arrival of warmer weather.

Bird lovers across the country will start seeing hummingbirds anytime now. Once April arrives, those in Virginia and North Carolina to Kansas and Oklahoma will begin seeing the birds in their backyards. As May rolls around, they’ll flock to the Northeast and Midwest.

If you miss seeing hummingbirds in your backyard, here’s when you can expect their arrival across the country.

East of the Rocky Mountains

Most of the eastern two-thirds of North America, from central Canada southward, are likely used to seeing the Ruby-throated Hummingbird. Once spring arrives, they flock to the Gulf Coast by early March and make their way northward in April and May, eventually ending up in northern states and southern provinces, with migrating males arriving about a week before females. You can expect to see these hummingbirds at flowering plants and nectar feeders in March until May, according to Audubon.

Southeast

From Cape Hatteras southward, in Florida, and around the Gulf Coast, hummingbirds are usually present year-round. What’s more, you’ll find there’s a higher diversity and greater number of birds present during the winter season. Those in coastal Texas and Louisiana may see hummingbirds visiting feeders towards the end of winter and beginning of spring.

Mountain West

Hummingbirds like the road-tailed, Black-chinned, Rufous, and Calliope varieties arrive in the mountainous West in spring once flowers begin to bloom. Those near the Mexican border will begin seeing these birds in early March. Before you know it, they’ll end up in the northern Rockies.

Southwest and West Coast

Those in the Southwest and the West may see hummingbirds all year long. However, in southern Arizona, New Mexico, and Texas species such as the Blue-throated, Rivoli’s, Broad-billed, and White-eared hummingbirds will be visiting nectar feeders in backyards. If you’re located on the West Coast from California to British Columbia, you may also see a plethora of hummingbirds year-round as well. These regions will also notice Rufous Hummingbirds moving northward early, making their way from Oregon to coastal Alaska where they breed.
