(269) For no valid reason that I could detect he then squealed once and would take no more food, although he did not seem to be frightened. While sitting on top of the ladder yesterday afternoon, waiting for the adults to put in an appearance, in order that I might observe any new phases in their habits, Brownie appeared first with earthworms. From previous observations I had about reached the conclusion that, on the comparatively rare occasions when earthworms were fed, Greenie was invariably the bearer. Perhaps these notes will show otherwise, but, in any case, that was my thought at the moment. In attempting to break them up on a horizontal limb, she dropped one piece after another until, from where I sat, there seemed to be nothing left. She dropped to the ground, but could find only a few fragments amongst the leaves and litter. Most of these she ate herself, Greenie begging for some, but not getting any. She then came to the nest with one almost invisible fragment, so I helped her give the young birds a respectable meal with soft food, after which she settled on the nest and dozed. Later while occupying the same position, I was able to observe an interesting excavation job by the same bird. She appeared from out of the shrubbery near the base of the ladder and commenced digging, apparently at random, pausing to inspect the hole made, from time to time, by putting her head in it and turning it from side to side. As a result of one inspection she changed the pit she was making into a trench, the direction of which appeared to have been determined by some observation made in the side of the hole, and its course was fixed in the direction desired by shifting her body into the new alignment. She now began to dig rapidly, the earth melting away in front of her attack, some portion of it seeming to be in continuous process of dissolving into space. From time to time she checked the direction of the trench by scrutinizing its face at close quarters much as a watchmaker inspects a watch with his eye glass. The action was exactly that of a dog following the burrow
