The Horned Grebe spends most of its life on the water, even as a chick. Like other Grebes, it can’t walk on land because its feet are so far back on its body. It can only flop and hop which means it can only take off from the water. It is also reported to eat its feathers which can be up to 55% of its stomach contents. Scientists believe the feathers protect the stomach from sharp fish bones that its gizzard can’t handle. The voice of the Horned Grebe is a series of interesting croaks and chattering, followed by a few long shrieks. In the summer you might hear whining. http://www.birdinginformation.com/birds/grebes/horned-grebe/
