Cedar Waxwing

I stopped by Lake Wilcox on my way home today to find the road closed and under construction. The are rediverting the creek that flows into the lake and putting in a new board walk there. Imagine it will look quite nice when they finish. Saw these lovely wax wings in the bushes not far from where I had parked my car. They seem to be eating these pretty little white flowers. Maybe bugs on them or nectar?
