Behavior
These birds feed by dabbling in shallow water at the edge of marshes or open water. They mainly eat plants; their diet may include molluscs and aquatic insects.
Blue-winged Teal are generally the first ducks south in the fall and the last ones north in the spring. Adult drakes depart the breeding grounds well before adult hens and immatures. Most Blue-winged Teal flocks seen after mid-September are composed largely of adult hens and immatures. The northern regions experience a steady decline in Blue-winged Teal populations from early September until early November. Blue-winged Teal in central migration areas tend to remain through September, then diminish rapidly during October, with small numbers remaining until December. Large numbers of Blue-winged Teal appear on wintering grounds in Florida, Louisiana, and Texas in September.

Famous quotes containing the word behavior:
“Excessive attention, even if it’s negative, is such a powerful “reward” to a child that it actually reinforces the undesirable behavior. You need to learn restraint, to respond to far fewer situations, to ask yourself questions like, “Is this really important?” “Could I let this behavior go?” “What would happen if I just wait?” “Could I lose by doing nothing?””
—Stanley Turecki (20th century)
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
