There are exceptions such as the Anna’s hummingbird. It is true that most hummingbirds fly north in the spring and south in the winter to complete the hummingbird migration. On the other hand, the Ruby-throated hummingbird, the most predominate of the eastern states may not arrive in the northern states and Canada until May. When to hang hummingbird feeders will vary according to the state you live in and the species you will see.įor example, the Costa's hummingbird of Southern California and other southwestern states begin to arrive in late February. This is also the time when nature lovers begin to put their feeders out. If you have seen hummingbirds in your state earlier than these dates please let us know by contacting us. We recommend hanging your feeders 2 weeks before the estimated time of arrival just in case they show up earlier. You will learn how this cross continental trip, truly an astonishing marvel of nature, is accomplished. Wondering how these little creatures accomplish this amazing feat year after year! We, and I'm sure you, appreciate everyone's participation in posting sightings every Spring during the hummingbird's flight to their Summer homes. If it wasn't for you, our visitors, we wouldn't be able to relay all this important information to our fellow "Hummingbird Lovers"! We compiled this data taken from our visitors sightings from previous When will the hummingbirds arrive?Īn easy way to estimate the Spring migration arrival datesīelow is a table of the estimated Spring migration arrivalsīy state. Submit your hummingbird sightings each Spring and Fall to update the latest travel patterns of hummingbirds to prepare for their arrival. See our state by state hummingbird migration table listing the average arrival dates. So this gives us hope that these very adaptable little creatures will have the capability to adapt and survive changing conditions. Studies have shown that hummingbirds have the sense to alter their routes according to the resources available. However, 300 miles or so east or west of their usual migration route there may be flowers ready to fuel their needs. Some years flowers will be in bloom when hummingbirds are passing through and another year they might not be blooming. Weather conditions will vary from year to year which affect when flowers will bloom in a particular area. They have the ability to alter their migration routes according to the flowers that are in bloom. If temps are generally getting warmer, flowers maybe blooming earlier resulting in flowers that are past bloom when hummingbirds arrive in the area Hummingbirds need the nectar from blooming flowers to fuel their long journey. Some studies/opinions hint that it could be a problem if hummingbirds arrive in a certain location expecting nectar but the plants are done flowering when they arrive. How does climate change affect the Hummingbird Migration? Some will spend the Winter along the western coast of North America. However, not all hummingbirds migrate each year. This usually starts in late August into September with the males leaving first followed by the females a week or two later. The Fall migration south back to Mexico and Central America starts when the abundance of insects (their main food source) starts to dwindle with cold temps. They will double their body mass in weight to “fuel-up” for the long journey. Males will usually migrate first followed by the females about 10 to 14 days later. Some scientists believe that they will also stop at the same feeders along their route on the same day every year during their migration journey. It is believed that hummingbirds will return year after year to the same feeders where they wore born. The Spring migration for the Ruby-throated hummingbird usually starts in February and ends in late May in their northern most habitat of Canada.
