A mixture of seeds and grains scattered outside to attract and feed wild birds, especially in winter.
Compound of 'bird' + 'seed.' Became common in the 1900s as people began intentionally feeding backyard birds for observation and enjoyment.
Sunflower seeds in birdseed are so nutritious that birds remember exactly which feeders had them and return to the same yards year after year—wild birds have better memory for food than you probably do!
