It appears the hummingbirds have left. True?
Individual adult males get the urge to leave first, followed soon after
by the females, and then finally the juveniles. Amazingly, once the
young have gained enough weight, they find their own way to the same
winter habitat as their parents - someplace where they have never been,
using the GPS in their head.
Hummingbirds migrate thousands of miles south every fall to reach their winter homes in Mexico and Central America under their own power. They fly about 23 miles a day by themselves, not in flocks or on the backs of geese.
It's not necessary to take down feeders to force hummingbirds to leave. The initial urge is triggered by the shortening length of sunlight as autumn approaches, and has nothing to do with temperature or the availability of food. However, weather is a factor. Hummingbird will take advantage of the winds to push them in the right direction.
Many hummingbirds migrate around the Gulf of Mexico, through Texas and northern Mexico to winter in Central America. Others will fly from Florida across the Gulf of Mexico to the Yucatan Peninsula.
hummingbirds aren't in as big a rush to go down south as they were to
find nesting grounds in the spring but they will leave us when the winds
and weather are just right.
