Hummingbirds are set to begin departing Michigan for their winter getaways down south.
The tiny, colorful birds will spend winter in Mexico and Central America, escaping the cold and snow in Michigan, before returning in spring 2027.
Here's what to know about fall hummingbird migration.
A hummingbird's heart beats up to 1,260 times a minute and its wings flap 15 to 80 times per second as they migrate south, Hummingbird Central says.
Hummingbirds prepare for this by gaining 25% to 40% of their body weight in the leadup to migration season, according to Hummingbird Central.
Hummingbirds typically migrate south in the fall from August to October in North America, EarthSky says. Hummingbird Central says male hummingbirds begin migrating south in mid-July, followed by females and later young hummingbirds.
Fall hummingbird migration is prompted by changing daylight, cooler weather and fewer flowers, nectar and insects during the season, along with the birds' internal biological calendar, Hummingbird Central explains.
During fall migration, hummingbirds fly south to destinations in Mexico and Central America, Hummingbird Central says.
Hummingbirds will arrive in Michigan in late spring 2027, based on typical migration patterns, and BirdWatching recommends putting out your hummingbird feeders by early April.
