Baby grebes spend time on their parents' back. They reach independence when they're between 10 and 16 weeks old.

Grebes, like this great crested grebe, have narrow wings, large feet, and lobed toes. The latter work like the blades of a propeller when they swim.

Grebes are small to medium-sized aquatic birds that range from 4 ounces to 3.8 pounds depending on the species.
