Guidepost 2: What are the four goals of the scientific study of human development, and what do developmental scientists study? 1  The study of human development seeks to describe, explain, predict, and modify development.

Dabbling ducks eat plants, seeds, grasses and other small insects and animals that they find on or under the water. Ducks which have broad beaks, (shovelers) sift their food for insects, snails and seeds from the mud.
All kinds of weeds and grasses make healthy treats for ducks that they will love. Ducklings can also eat anything on this list as long as the treat can be cut into very small pieces or is soft or mushy to prevent choking. The sooner you introduce baby ducks to a variety of foods, the more accepting they will be and the more apt to try new treats.
