A REPORT ON EXPEDITIONS MADE IN 1907 UNDER THE 
“NORTH AMERICAN ORNITHOLOGY FUND.” 
a) L\ HROUGH the continued generous coéperation of the sub- 
y Kua scribers to the “North American Ornithology Fund,” 
further important additions have been made to our series 
of “Habitat Groups” of North American birds. 
The collections and field studies on which these groups 
are based can be made only during the nesting season. 
The work for this year was therefore planned to cover as long a nesting 
period as possible, beginning with southern species which nest as early 
as January and ending with northern birds which are not concerned with 
domestic affairs until July. In brief, the schedule was as follows: 
March.— Southeastern Bahamas for Man-o’-war Birds and Boobies. 
April.— Southern border of the Florida Everglades for Spoonbills 
and Ibises. 
May.— South Carolina for White Egrets. 
June.— Plains of Saskatchewan for Wild Geese and Grebes. 
July.— Summits of the Canadian Rockies for Ptarmigan and other 
Arctic-Alpine Birds. 
The species of birds here included show wide variation in form and in 
nesting habits, while the country in which they live — their “habitat”? — 
presents an even greater diversity, as we pass from a coral islet to a 
mangrove swamp or a cypress forest and over the rolling plains to the 
snow-clad mountain crests. The subjects selected were thus designed 
to add to the zodlogical as well as geographical instructiveness of the 
exhibits as a whole. 
A series of mishaps so prolonged the Bahaman expedition that I was 
prevented from reaching the Everglades in time to find Spoonbills nesting, 
but, with this exception, the schedule outlined above was followed with 
eminently satisfactory results. 
On March 28, with Dr. Alfred G. Mayer and Mr. George Shiras, 
3d, I sailed from Miami, Florida, for Nassau, Bahamas, aboard the 58- 
foot auxiliary ketch, “Physalia,” belonging to the Marine Biological
