American White Pelicans spend the summer at Chase Lake National Wildlife Refuge breeding and nesting. They show up as the cold weather starts to disappear in April. They begin nesting and laying eggs in May. Usually, the eggs hatch by June and the pinkies (smaller than juveniles; without feathers) have all summer to grow and learn to fly. When the pelicans are at their home in the summer, it is referred to as their breeding ground.
