 Hummingbirds have exceptional visual acuity providing them with discrimination of food sources while foraging.Although it is commonly believed that hummingbirds are attracted to color while seeking food, such as red flowers or artificial feeders, experiments indicate that location and flower nectar quality are the most important "beacons" for foraging.Hummingbirds depended little on visual cues of flower color to beacon to nectar-rich locations, but rather they used surrounding landmarks to find the nectar reward.
