(513) administering worms, his scrutiny of the interior fabric of the nest has been constant and at bill's length. Every portion except that [illegible] covered by a nestling has been repeatedly examined and probed. As a practical result, he discovered two meal-worms and pulled them out. I believe also that he is on guard against ants. While at the nest his vigilance in this respect has been unceasing. One chick has its lower mandible longer than the upper. Another, during this period, was much neglected in feeding and was jammed down in the bottom of the nest. B objected a little to my digging him out, as I had to upset things a little, and pecked me lightly, but he immediately took worms for him as soon as he opened his bill.
