Before Migration Begins
Before Migration Begins, Ruby-throated Hummingbirds double their weight from 3 grams to over 6 grams prior to departing. They don’t stay pudgy for long, though. In northward migrations, it’s not uncommon for a hummingbird to weigh around 2.5 grams when it reaches U.S. shores!
Each year, hummingbirds embark on two migrations – one north and one south. These migratory journeys, which can span hundreds or thousands of miles, require immense preparation and a shocking amount of energy from these small birds – the smallest in the world.
In the fall hummingbirds can set out as early as late July and the last stragglers will cross the southern U.S. border by late October. It’s this amazing cycle of hummingbird migration that can also bring a sudden swarm of activity to your hummingbird feeders. If you have a well-maintained hummingbird feeder, expect plenty of new visitors as they try to boost their energy before the next stage of their journey.
I am taking lots of photographs of them right now before they leave. I look forward to seeing them again next year.
