From this time on the birds came and went without hesitation, the only serious delays in our operations being due to the drifting clouds, which now and then obscured the sun and rendered the light too weak for the rapid exposures necessary. One of the birds, the one we took to be the female, was a little more courageous than the other, and it is her picture that appears oftenest. The timid one,--the male,--even went so far on several occasions as to himself devour the worm he had brought rather than trust himself at close quarters with the unknown enemy, although his mate was at the time coming and going industriously and keeping the little folk well supplied with the great larvæ. Surely personal traits and individuality are quite as well marked in the bird world as higher in the scale! After we had made several more exposures similar to the first, one of the best of which shows the bird, worm-laden as before, balanced on the edge of the hole and taking the usual last look at the camera, we turned our attention to catching her as she was coming out. This required quicker coöperation between eye and hand, as the exit was generally made with a dash; but the accompanying picture, with head just emerging, will show that we were fairly successful.
Having concluded from all indications, chief among which was the immense number of huge caterpillars carried in to the young, that the latter must be fairly grown, we decided to expose the nest and complete our collection by securing the entire family. So carefully sawing away the front wall of the cavity with a keyhole saw carried for just such purposes, we gave the little fellows within their first view of the outside world. I fear they must have thought the manner of opening their second shell a rather rude one, and the outlook somewhat forbidding. They were pretty little youngsters, fully grown, with clean, jaunty coats, and a grown-up 'chickadee-dee,' just like the old folks. Though somewhat dazzled at first by the sudden flood of bright sunlight, they were, after a little coaxing, induced to sit out on the veranda that had been improvised for them; but, like youthful sitters generally, they were hard to pose, and after many exposures, we succeeded in getting no more than two of them at once. The prettiest one of all, showing two of the little fellows as they finally settled down contentedly in the warm sunshine, was obtained at the expense of much patient effort and a great deal of slushing back and forth in mud and water between boat and camera, and it was gratifying to find that one at least of the negatives did fair justice to the situation.
