Fall hummingbird migration is in full swing!

Have you noticed how early the sun is setting? Do you know who else is paying attention to the loss of daylight? Our Ruby-throated Hummingbird friends!

Did you know that the length of daylight is the most important factor in determining when hummingbirds migrate? Yep, when days get shorter hummingbirds instinctively eat more nectar and insects in preparation of making their exhausting flight back to their wintering grounds in Mexico, Central and South America. To our tiny winged friends, food is energy. They will need to almost double their body weight daily to support their long flight!

Some hummingbirds begin to migrate in early August, but most don’t begin their journey until late August or early September. Just as male hummingbirds are the first to migrate north in the spring, they are the first to head south, followed by adult females and then juveniles. Even as the hummingbirds you have fed all spring and summer depart, birds that nested further north in the United States and southern Canada will visit your feeder as they migrate through the area.

Hummingbirds migrate during the day and spend most of their trip at tree height, continually looking for food to refuel. Birds hatched late in the breeding season depart later than those hatched earlier and they may still be migrating through even into October. So, keep your feeders cleaned and filled a little longer!
