Several May lists of birds arrived too late to be included among 

 those which appear in this number. They will be published in the 

 September number. These lists give evidence that there was an 

 unusual warbler movement in the central districts during the first 

 half of May. 



We are pleased to notice that the University of Michigan will 

 conduct a Biological Station at Douglas Lake, some seventeen 

 miles south of the Straits of Mackinac, during the eight weeks 

 from July 3 to August 25, inclusive. The work will cover the 

 Natural History of the region. Dr. Reuben Myron Strong, of the 

 University of Mississippi, will have charge of Ornithology. Dr. 

 Otto Charles Glaser, of the University of Michigan, Ann Arbor, is 

 the Director. The Station is fully equipped for the work which 

 it undertakes, and will prove unusually attractive to those who 

 wish to acquaint themselves with the living things in their nat- 

 ural environment. 



We know all too little about the food and food habits of birds, 

 less even about the food and feeding habits of nestlings, and still 

 less about the percentage of mortality of nests, eggs, and adults 

 during the season of nesting. These are problems which can be 

 best worked out in the late spring and summer seasons. Every 

 season should witness progress along these lines. We hope that 

 this season may be more than usually fruitful of facts gathered.
