 8 TIlE CONDOR .... Vol. XX of twelve a night in the migration season. The birds killed at these lighthouses would probably amount to quite a large number from year to year. But when we remember that there are twenty-seven other stations reporting no destruc- tion at all, we see that the number of birds ilted in {'his Way on the whole coast must be conparatively slight.  II. The destruction of birds at the lighthonses of the California coast is confined ahnost entirely to water fowl and shore birds. Only two Stations re- port any land birds destroyed..

"Grey Shore Bird" ' 2 The evidently snall number of land birds "killed at ;'he lighthonsesl of the coast is surprising, since we have been. accustomned to think of then as ',perish- ing in great numbers at similar places in Europe,.,. in th Great Lakes and on the Atlantic coast. It nay be that the number so killed in the regions naned has been overestinated, if, indeed,. any careful and extensive study of the natter has been made. But, naking all such allowances, it seems probable that the nunber of birds killed on this coast is 'far below the usual quota else- where. The writers suggest the following reasons as offering a plausible ex- planation of the difference. 1. The character of bird migration on the Pacific Coast. It is a well known fact that western birds do not nigrate with that concentrated wave movenent co,tanon among the birds of our Eastern and Middle states. In that 'egion we awoke stone fine spring norning to find forest and garden and way- side weeds nelodions with song where all was wintry silence but yesterday. This does not happen.in California. Migrations here are nore leisurely and widespread, hence less dangerous to the bird travellers. 2. The character of the California coast. A glance at -the-map will show that the portion of the .Nolh .merican coast conprised .within the boundaries of California .pushes out:westward into the Pacific Ocean ,in one vast convexity. Birds travelling on.this coast and taking "short cuts" will be' thrown away l'ron the ocean...,,'O te other hand the Atlantic coast of our cou'nty conqists ' of three great concavities and nany lesser indentations of the 'sea. Birds tra- velling On the Atlantic. coast have numerous sea trips, more or le xtended, and will consequrtly be continually passing near lighthouse stai0ns,  ': 3 The strutl{reland locationqf California lghthouses.. The sefiior au- thor has seen over half of the thirty-six lighthouses from .whichrep,orts have been received, dn'd'asay that for the most part they are c0'rap,ably low structures. The tall, brick-chimney type of lighthouse which one sees so often on the Great Lakes seems to be almost wholly wanting on this coast.
