These grebes are only occasionally seen in flight; once on the wintering grounds they seldom fly, and they migrate almost entirely at night. Like other grebes, the young can swim and dive immediately after hatching but are often seen riding on the parents' backs. And like other grebes, the Horned Grebe swallows large numbers of its own feathers, which lodge in the stomach and prevent fish bones from passing into the intestines. Even newly hatched young eat feathers, taking those of their parents. Birds of fresh water during the nesting season, Horned Grebes migrate to salt water for the winter, and therefore are thought of as saltwater birds, but some can be found on open water in the interior of California and other western states.
