The website went on to say that wind is another variable in nectar production.
"High winds that are sustained for long periods of time can actually dry nectar pools inside the flowers. ...Wind can quickly dry up soil moisture and will increase plant transpiration and evaporation rates. Although this type of water loss may be small, it could reduce nectar production as the water moves more rapidly through the plant instead of being allocated to nectar production," the post continued.
Nectar, while it is important to honeybees, is also very essential for hummingbirds.
"Hummingbirds routinely ingest more than their own weight in nectar each day..," penned author Noah Strycker in his book "The Thing With Feathers".
With all the fighting and flitting there's no doubt the that the winged warriors need a lot of food.
A post on hummingbird facts on The Cornell Lab's All About Birds website stated that ruby-throated hummingbird beats its wings about 53 times a second.
The post identified the hummingbird as "eastern North America’s sole breeding hummingbird" and stated that folks should "Enjoy them while they’re around; by early fall they’re bound for Central America, with many crossing the Gulf of Mexico in a single flight."
Locally, birder Gary Edwards in his book "Birds of Venango County" said the ruby-throated hummers arrive in mid April an departs by early October.
