Why are there more hummingbirds in the fall? Nesting season is over for the hummingbirds in Michigan by the end of June. Once breeding territories no longer have to be guarded, hummingbirds wander widely. Just before they answer the call to travel south, hummingbirds eat in excess to build a layer of rich fatty fuel just under their skin. You can notice the extra fat along the belly, back, and throat. A hummingbird actually gains 25 – 40% extra body-weight to have enough fuel to migrate thousands of miles south. You will notice them getting fatter and fatter and then one day they fly to their wintering grounds.
Do I make the nectar recipe stronger to give them more energy? It's not necessary to make your sugar solution stronger. The 4:1 ratio is the closest to the favorite flowers that hummingbirds visit. That would be four parts water to one part plain white sugar. Click HERE for the nectar recipe.
Should I make the sugar solution weaker to encourage them to leave? I would continue to feed the hummingbirds the same nectar solution until they are fat enough to move further south. Don't rush them. Let them leave when they have enough energy and the weather is favorable.
Where do Ruby-throated hummingbirds spend the winters? Most Ruby-throated Hummingbirds winter in southern Mexico, Central America, South America, and the West Indies. A few remain along the Gulf coast and on the Outer Banks of North Carolina.
