STATUTE MILLS FROM 
NEAREST KNOWN COLONY 
Fig. 14. Abundance of Glaucous Gulls vs. distance from the nearest shore. Since Glaucous Gulls may 
nest at many points along the shore, comparison is made between abundance and distance from the nearest 
land. All entries are included. 
Fig. 15. Abundance of Black-legged Kittiwakes vs. distance from the nearest known colony. Because of 
incomplete knowledge of nesting colonies, observations from 10-minute counts near and in Kotzebue Sound 
are not included. All other observations are plotted. 
Fig. 16. Abundance of murres vs. distance from the nearest known colony. Due to the great amount of 
data available, only 10-minute counts are plotted. Because of incomplete knowledge of nesting colonies, data 
from 10-minute counts in and near Kotzebue Sound are omitted.
