If she found it hard to sit there day after day, she made no fuss about it; and probably she really wanted to do that more than anything else just then, since the quiet patience of the most active birds is natural to them when they are brooding their unhatched babies. Then, too, there was her beautiful mate for company and help; for when Ardea needed to leave the nest for food and a change, the father-bird kept house as carefully as need be. To her next-bush neighbors and the little blue herons Ardea paid no attention, unless, indeed, one of them chanced to come near her own mangrove bush. Then she and her mate would raise the feathers on the top of their heads until they looked rather fierce and bristly, and spread out their filmy capes of dainty plumes in a threatening way. That criss-cross pile of old dead twigs was a dear home after all, being lined, you will remember, with the love of Ardea and her mate; and they both guarded it as well as they were able. At last the quiet brooding days came to an end, and four funny little herons wobbled about in Ardea's nest. Their long legs and toes stuck out in all directions, and they couldn't seem to help sprawling around. If there had been string or strands of moss or grass in the nest, they would probably have got all tangled up. As it was, they sometimes nearly spilled out, and saved themselves only by clinging to the firm sticks and twigs. So it would seem that their home was a good sort for the needs of their early life, just as it was; and no doubt a heron's nest for a heron is as suitable a building as an oriole's is for an oriole.
