Before their ranks were so painfully thinned by the plume-hunters, these nesting communities contained hundreds and even thousands of individuals. The nest is built upon the mangrove bushes or upon the broken reeds and rushes in the swamps, and is said to be rather more carefully and compactly built than are the herons' nests. The eggs are three or four, rarely five in number, and are laid about May 1 in many localities, later in others. They appear large for the bird. In shape they are usually rather long ovate, and in color are gray or ashy-blue, irregularly and rather heavily blotched and spotted with reddish and umber browns of various shades.
Some specimens are very pretty.
The story of their great abundance, persecution, rapid decline, and almost death, if written, would read like some horrible nightmare. We are sometimes led to wonder if there is anything so sacred as money. We might be able to derive some comfort from the thinning ranks of many of our birds, perhaps, if we could be sure that when these were gone the work of extermination would cease. But when one species disappears another, less attractive before, will be set upon, and thus the crusade, once begun, will finally extend to each in turn. This is not theory but fact.
