PACIFIC SCIENCE, Vol. Ill, April, 1949 
in part to a concentration for breeding in the 
winter, although the species nests the year round. 
Domestic Canaries decreased greatly in num- 
bers from 1922 to 1945, but have since increased 
sharply. Domestic Pigeons transplanted some- 
time after 1922 are increasing rapidly. Two 
species, the Laysan Rail and the Laysan Finch, 
were abundant in 1922 and maintained this 
abundance until the late 1930’s; rats probably 
accounted for the last individuals in early 1945. 
Brown Boobies were not seen in 1945 and 1946, 
but they have never been abundant on Midway.
