Casualties at other stations, from which reports have been received, are so rare they may be considered accidental. As some reports do not give an estimate of the yearly mortality, merely stating that a large. > Figure 3—Map of British Columbia showing location of the lighthouses which are destractive of bird-life • Stations where serious destructions occur.
