Happy Hummingbirds in Flowers, mixed media painting by Michele Avanti

This painting is a huge mix. The hummingbirds are done with pen and ink, and acrylics. The flowers are photographs I took in Umpqua, Oregon, The backdrop is a three more photographs of maple leaves and dusty miller, each digitally treated. After scanning the original hummingbirds, I created several composites digitally in photoshop.

Hummingbirds are New World birds that constitute the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5�13 cm (3�5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird, weighing less than a U.S. zinc penny (about 2.5g).
They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing flapping rates, typically around 50 times per second,[1] but possibly as high as 200 times per second, allowing them also to fly at speeds exceeding 15 m/s (54 km/h; 34 mph),[2] backwards or upside down.[3][4]
Hummingbirds have the highest metabolism of any homeothermic animal.[5] To conserve energy when food is scarce, they have the ability to go into a hibernation-like state (torpor) where their metabolic rate is slowed to 1/15th of its normal rate

Hummingbirds are specialized nectarivores[9] and are tied to the ornithophilous flowers they feed upon. Some species, especially those with unusual bill shapes such as the sword-billed hummingbird and the sicklebills, are co-evolved with a small number of flower species.
Many plants pollinated by hummingbirds produce flowers in shades of red, orange, and bright pink, though the birds will take nectar from flowers of many colors. Hummingbirds can see wavelengths into the near-ultraviolet, but their flowers do not reflect these wavelengths as many insect-pollinated flowers do. This narrow color spectrum may render hummingbird-pollinated flowers relatively inconspicuous to most insects, thereby reducing nectar robbing.[10][11] Hummingbird-pollinated flowers also produce relatively weak nectar (averaging 25% sugars w/w) containing high concentrations of sucrose, whereas insect-pollinated flowers typically produce more concentrated nectars dominated by fructose and glucose..
