R.E. Johnson 1968 May 27 Amchitka Island, Alaska (cont.) Journal 43 Ninety two bldg were searched and 16 active nests were found. That is, 17.4% of all buildings had active nests and 46.7% had either active or old nests in them. Slightly more than half of the buildings examined were quonset huts and yet less than a third of the new nests were found in them. There were also less old nests in quonset huts than in other buildings but the difference was not nearly so great. Percentage figures in the last two lines of the previous page document these trends. One possible reason for this great difference is that a lower percentage of quonset huts contain suitable nest sites (shelves hanging from wall are usually the only suitable nest site in a quonset hut & these are absent from many of them). When percentages are refigured on the basis only those of huts with shelves (ie. none without shelves), then the percentage with nests increases from 9.8% to 20% and the percent with nests (new or old) increases from 37.3% to 85%. The percent for new nests is still below the figure for "other bldge", but the percent for all nests is higher. However when buildings lacking good nest sites are excluded the figure for all nests (new & old) raises from 58.5% to 88.9% which is similar to the quonset hut figure. However the figure for new nests is now raised from 26.7% to 40.8% which is double that for quonset huts. It quonset hut is not clear why nests should lag behind
