Nature Walk: Not a Duck

Posted on April 28, 2014 at 10:00 AM by Kerri Sorrell

Water birds are not all ducks, geese or herons.  Less obvious but often accompanying them are pied-billed grebes.  They are about the size of the smallest ducks, but have lobed not webbed feet for swimming.  One may see a single bird or perhaps a pair, but not a large group as with many other waterfowl species. Aquatic organisms such as crayfish, insect larvae, small fish and green vegetation are their primary food source. To escape danger the birds dive underwater. One may also observe young birds riding on the backs of a parent bird just after hatching.
