The actions of the female were interesting in the extreme. Her first move was an attempt at concealment through protective mimicry—a rare device among birds. Stretching her neck to the utmost, she pointed her bill to the zenith, the brownish marks on the feathers of the throat became lines which, separated by the white spaces between them, might easily have passed for dried reeds, and the bird’s statuelike pose, when almost within reach, evinced her belief in her own invisibility.^{33, 34} The pose recalled Hudson’s experience with a wounded Least Bittern (_Ardetta involucris_, a near relative of our bird) in the marshes of La Plata, where a bird at his feet, in the same position as the one before me, was discovered only after careful search, and which, to the naturalist’s amazement, slowly revolved as he walked around it, with the presumable object of keeping its protectively colored breast turned toward him. [Illustration: 34. Least Bittern on nest mimicking its surroundings.] My bird, however, was among fresh reeds, and while one can not doubt the effectiveness of its attitude and color, when seen among dead reeds or grasses, neither were of value among its green surroundings. With the light on the wrong side and the reeds swaying violently in the wind, we essayed to picture the bird, and the best of several attempts made under these adverse conditions are here given. Covering my hand with my cap I held it toward her, when, convinced that her little trick had failed, she adopted new tactics, and struck at me with force and rapidity, which made me thankful that my hand was protected. Her bright yellow eyes glared with the intensity of a snake’s, and her reptilelike appearance was increased by the length and slenderness of her head and neck. Her courage was admirable; she not only displayed no fear, but was actually aggressive, and with a hissing _hah_ struck viciously at my hand each time it was placed near the nest. As I quickly retreated on each occasion, and at length made no further move toward her, she decided to withdraw, perhaps to join her cautious mate, who from the reeds had been uttering a warning _tut-tut-tut_ at intervals. Very slowly and watchfully she left the nest, and when she had advanced a few feet through the reeds I again ventured to touch her platform home, putting my hand, however, under it; but the motion instantly attracted her attention, and, darting back to her post, she was on guard in a moment. Then I left her, retiring from the field fairly vanquished in my first hand-to-bill encounter with a wild bird. I hope she laid a full complement of five eggs and from them reared five birds worthy representatives of their mother.
