One kept up with an automobile going 45 m. They breathe at the same rate. It can hover long enough to suck out all the nectar it needs from a flower. Hummingbirds are very intelligent, and are able to remember places and individual people from one year to the next. They communicate with each other primarily by chittering and other vocalizations, and by flying toward one another aggressively, to chase each other away.
They use these to display to one another. Females find it attractive, and other males are repelled. Male hummers are VERY feisty and territorial and constantly bickering with one another, and the red feathers are part of this territorial display. So they have two functions-attracting a female and defending their territory. The brilliant, iridescent colors of hummingbird plumage are caused by the refraction of incident light by the structures of certain feathers. Like any diffraction grating or prism, these structures split light into its component colors, and only certain frequencies are refracted back to your eyes.
The apparent color of any particular part of a feather depends upon the distance between the microscopic ridges in its gridlike structure. The resulting colors are much more vivid and iridescent than those of birds with only pigmented feathers. Iridescent hummingbird colors actually result from a combination of refraction and pigmentation, since the diffraction structures themselves are made of melanin, a pigment.
A very few hummingbirds are true or partial albinos. That means their feathers and sometimes their whole bodies have no pigment. Hummingbirds never stop beating their wings, and with their tiny size can look like large bumblebees in the air. They fly in a direct path unless they are making a male display flight. Displaying male ruby-throats fly in a wide arc—about degrees, looking like a half-circle—swinging back and forth as if suspended at the end of a long wire.
Their wings make a loud buzz at the bottom of the arc. Perhaps you've heard them, too—the name hummingbird comes from the buzzing sound of their fast-flapping wings. Hummingbirds, which are tiny, colorful, thin-beaked birds, get their name from the humming noise that occurs when they flap their wings very fast. These tiny, feathered creatures are astounding to even the most experienced birders. From distinctive physiological features to intriguing migration patterns, the following facts will get you acquainted with the world's smallest birds.

Although these plants are beautiful, they are unfamiliar to hummingbirds and will not provide the nectar they require. Please choose your plants wisely. If you love hummingbirds as much as I do, get your own feeder, fill it with homemade nectar , and watch the tiny birds come to eat. You will enjoy seeing the hummingbirds, and you will be helping them out with their need to eat a lot! Lisa M. Genier joined the Council in working as its Legislative Associate in the Albany office.
During her tenure, she played a role in the creation of the Environmental Protection Fund, which has been used to fund land purchases and environmental programs in the Adirondack Park and around the state. She was also a member of the negotiating teams that worked on re-licensing agreements for several hydroelectric facilities in the Park, which preserved thousands of acres of land, expanded recreational opportunities, and protected other natural resources.
