6 Age Distribution - Black-legged Kittiwake Section(s) Percent Adults Sample Size "A" North R + S + T 17 72 Center U + V + W 29 68 South X + Y + Z 100 7 "B" (Outside) R + U + V + Z 36 84 Total Grid 27 147 (Inside) T + W 19 37 The table above shows two simple ways of analyzing the age distribution of the present survey's data. Direct interpretation of each method suggests: 1) Adults move south before or more rapidly than nonadults as in "A;" 2) Adults move south at a greater mean distance from land than nonadults as suggested in "B." From the general knowledge of gulls, the first interpretation does not strike me as being most tenable particularly when the second interpretation would also explain the first set of data. Further analysis of back data should be done.

Neither of the other two species has been definitely recorded in the last four surveys.
