In 1994 when the availability of small fish appeared to be relatively good, the smallest chick from an inadvertantly artificially-created 3-egg clutch received occasional supplemental feedings by humans for two weeks. These supplemental feedings probably prevented this chick from starving. During its period of most rapid growth (after the linear growth phase of its two siblings had ended), however, it did not receive supplemental feedings from humans, but was instead was fed only by the two adult birds attending the nest. All the chicks in this brood eventually fledged, indicating that the pair was capable of meeting the feeding demands of three large chicks.
