Thus in five hours the young had been fed four times only, once by the male, and three times by the female, or at the rate of once in every seventy-five minutes, the intervals thus being longer by twenty-one minutes—instead of shorter as hoped—than those of the first study. However, on my next visit the following day, the thing I had set out to determine came about. It was about when I arrived at the site, and when I left, and during those five hours the young were fed eleven times, four by the male, and seven by the female, or at the rate of once in every minutes, thus proving that a much quicker rate of feeding than about once every hour does at times occur. On one occasion, the female perched at the base of the nest and remained there for five minutes before feeding the young. The day fol- lowing (Sept. 10th), saw me again at the site, when I quite expected to find that some of the young would have vacated the nest, so lively had most of them been on the previous day. However, they were all there, but I had to be very careful in setting up the camera and removing a branch I had fixed in the ground the day previous—before leaving—to shield them somewhat from the rays of the sun, but this I managed to do successfully, al- though one of them almost took to flight during the process. I arrived at one o'clock, and left again at three-thirty during which time the young were fed five times, three by the male, and twice by the female, or at the rate of once in every thirty minutes, another
