From the feisty Rufous Hummingbird to the more common Ruby-throated Hummingbird, hummingbirds are some of the most fascinating of wild birds to watch. While there are hummingbird feeders available to attract them to your garden or window for your viewing pleasure, you can also attract them, while providing them with the energy that they need with hummingbird nectar. Despite being quite small in size, hummingbirds have relatively big brains and possess the ability to rotate their wings in a full circle. This full rotation allows them to fly forward, backward, up, down, sideways as well as just hover. Given the right hummingbird food, you will be able to attract various species of hummingbirds. As many male hummingbirds tend to be territorial after perching themselves upon hummingbird feeders, their displays of territoriality are among the many interesting behaviors observed by prevalent birdwatchers. Known to reach relatively high speeds and fly long distances, hummingbirds require hummingbird nectar to fuel their active lives and fast metabolisms. Whether you are an avid birder or a beginning bird watching enthusiast, attract a wide variety of hummingbird species to visit your garden feeder with fresh hummingbird food.
