There are plenty of twigs at the Lincoln Rookery for the Great Egrets and Great Blue Herons to use as nest building material. The rookery is crowded with birds and the trees criss cross one another with branches and twigs. It wasn’t easy to capture a bird carrying a twig with an unobstructed background. This Great Egret suddenly appeared carrying a twig for its nest but until it flew directly in front of the twiggy tree, its wings shaded its body. As it flapped its wings, suddenly the morning sun caught the underside of the bird and the light helped the bird stand out from the background.
