Ruby-Throated Hummingbird (Female)

Ruby-Throated Hummingbird (Female)
Ruby-throated hummingbirds are solitary. Adults of this species are not social, other than during courtship; the female also cares for her offspring. Both males and females of any age are aggressive towards other hummingbirds. They may defend territories, such as a feeding territory, attacking and chasing other hummingbirds that enter. In late summer to early fall they fatten up for migration. This is important because, as part of their migration, they must fly across the Gulf of Mexico. This feat is impressive, as a 500-mile, non-stop flight over water would seemingly require a caloric energy that far exceeds an adult hummingbird's body weight of 3 grams. However, researchers discovered the tiny birds can increase their body mass up to double with lean mass in preparation for their Gulf crossing. The additional mass, stored as fat, provides enough energy for the birds to achieve the flight. No processing or touch-ups.
