These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water.
Anatids are generally herbivorous as adults, feeding on various water-plants, although some species also eat fish, molluscs, or aquatic arthropods.
The anatids are generally seasonal and monogamous breeders.
A number of species do annual migrations.
A few species have been domesticated for agriculture, and many others are hunted for recreation food. Duck, eider, and goose feathers and down have long been popular for bedspreads, pillows, sleeping bags, and coats.
Since 1600, five species of ducks have become extinct due to the activities of humans, and subfossil remains have shown that humans caused numerous extinctions in prehistory. Today, many more are considered threatened.
