While allowing for the possibility of work at any time of the year, increased wind velocities and shorter days in winter favor the summer season. On present evidence the optimal time would have been August-September when the mean maximum temperature range is reached. The immature petrel bones in several of the rockshelter midden points to the same time of year. The faunal evidence also suggests the intriguing possibility that the scheduling of work in the quarry was planned to coincide with the optimal time for hunting petrels, so that it was the availability of this particular species of bird that was the primary determining factor of seasonality in a quarry that is inferred to have been "the central place" in Hawaiian adze manufacture. The bird cooking stones from this site [Kalepeamoa] are, I think, symbolic of the season exploitation of upland bird communities by specialists.
