Visualize watching a bright green hummingbird in your garden moving from flower to flower in search of the tasty nectar within. These beautiful and tiny birds weigh about 2 to 20 grams and are found in a wide variety of environments from the high Andes to lowlands, and from dry desert areas to rainforests. They have slender beaks, extensible tongues, ten primary feathers, and tiny feet suitable for perching but not walking.
Hummingbirds can fly straight up, straight down, backwards, left, right, and even upside down. While most birds obtain their flight strength only from the down stroke, hummingbirds have power on the up stroke as well.
Most hummingbirds flap their wings about fifty times a second and have a very fast heartbeat and high body temperature. They feed every ten minutes or so throughout the day and typically consume two-thirds of their body weight in a single day. Their source of nutrition is primarily nectar from flowers, as well as sources of protein from insects and tiny spiders.
