- A birdfeeder, bird feeder, bird table, or tray feeder are devices placed outdoors to supply bird food to birds (bird feeding). The success of a bird feeder in attracting birds depends upon its placement and the kinds of foods offered, as different species have different preferences.
- Bird feeders often are used for birdwatching and many people keep webcamstrained on feeders where birds often congregate.
- Feeding wild birds does carry potential risks. Birds may contract and spread disease by gathering at feeders; poorly maintained feeding and watering stations may also cause illness.
- Birds at feeders risk predation by cats and other animals, or may incur injury by flying into windows.
- One of the birds may also potentially dominate the feeder and attack other indigenous birds.
