Discussion

 Around their colonies, ibises eat crabs and crayfish, which in turn devour quantities of fish eggs. By keeping down the numbers of crayfish, the birds help increase fish populations. In addition, their droppings fertilize the water, greatly increasing the growth of plankton, the basic food of all marsh life. White Ibises gather at dusk in spectacular roosts, long lines of birds streaming in from all directions.
