Some waterfowl, Blue-winged Teal Anas discors, stopped on the pond today. They are some of the last ducks to arrive each Spring on breeding grounds because of their long migration from South America or Mexico. Smaller than Mallards, each weighs 9 to 18 ounces. They feed by 'dabbling' for plant matter under the water, or for crustaceans or insect larvae in the water.
