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.
Leafy greens are an important part of a duckâs diet. I start our ducklings off young getting used to cut weeds and grass, lettuce and Swiss chard. Ducks wonât eat wilted greens, so I put the âsaladâ in their water tub. It stays nice and fresh that way and keeps them occupied dabbling for the leafy treats. Ducks also enjoy fresh peas or corn kernels, cucumber pieces, watermelon and cut tomatoes.
