Every year, the American White Pelicans migrate to the Grand Lake Ok area. During the migration period, it is a wonderful sight to see them together throughout the area. Usually migration will begin any time between February and May. They will continue to appear through anytime in early September through November. The American White Pelican can weigh from ten to thirty pounds. Females and males look exactly alike, but may different in weight. They carry the second widest wingspan among North American birds. On average, the birds live around 16 years. The record time of living is 34 years. This pelican is different than other breeds. The American White Pelican does not dive for its food, they catch food while swimming. Each bird will eat approximately four pounds of food each day. During the month of September (toward the end of the month each year), Grand Lake Ok celebrates the Pelican Festival. Other area activities are also planned around this event, so there are plenty of other things to do. This is a great time to plan a trip to Grand Lake with the children. It is a beautiful scene to see and should not be missed by anyone!
