Bird feeders are objects that are designed to provide food for birds. They are needed for pets, and are sometimes put outside for wild birds; this is especially done in the winter, when birds would not otherwise be able to collect enough food. Bird feeders come in many different forms.
While seed is commonly used to fill a bird feeder, some are designed for nectar feeding birds. Hummingbirds are one such bird that specialty feeders are designed for. They act as a reservoir for hummingbirds to drink from. The nectar used is a simple mix of sugar and water.
