AVAILABLE INSECT FOOD FOR GROUSE CHICKS* 



Grouse chicks, for the first few weeks of their existence, are largely dependent upon insects 

 and closely related forms of animal life as a source of food. Since their welfare is thus con- 

 cerned with the availability and abundance of this kind of food, population studies of insects 

 and their allies were undertaken. To this end samplings were carried out in each of the 

 various types of cover that make up grouse habitat and under varying weather conditions 

 from June 2 to July 1, 1936 on the Connecticut Hill area and from June 9 to July 14, 1936 

 on the Adirondack study area. These were repeated on the former area from June 1 to July 

 1, 1937.
