LET'S PRESERVE THIS PRAIRIE 
A few weeks ago an appeal for funds to purchase the proposed 
Prairie Chicken Retuge at Bogota, Illinois, was sent to every I.A.S. 
member. Many of you have already responded, but some of you 
may have placed the letter aside, intending to take it up later. If 
you cannot tind the request among your other correspondence, just 
remember the address: George Fell, Treasurer, Prairie Chicken 
Foundation of Illinois, 819 N. Main Street, Rockford, Ill. We have 
already received contributions from as far away as Wyoming, New 
York, and Alberta in Canada. Why not match these efforts as an 
Illinoisan? 
Correction, Please! 
IN THE SEPTEMBER 1961 issue of the Audubon Bulletin (No. 119), on page 
17, it was stated that the Leach’s Petrel (Oceanodroma leucorhoa) is 
“, . The only petrel which nests on the American Continent.” The state- 
ment is in error, as the Fork-tailed Petrel, Oceanodroma furcata, breeds 
on the western coast of North America from the Aleutians to northern 
California, and the Ashy Petrel, Oceanodroma homochroa, breeds on the 
Santa Barbara Islands off the California coast. Actually, the Leach’s Petrel 
and its West Coast subspecies is the only petrel that nests along both the 
east and west coasts of the North American Continent.
