In a pesticides-wildlife study by the Massachusetts 

 Cooperative Wildlife Research Unit, much is being 

 learned about the biology and life history of the towhee. 

 Here are (above) a female towhee caught in a mist net, 

 (upper right) a clutch of four eggs, (right center) two 

 fledglings, and (lower right) a nestling being banded.

at the request of the U.S. Study Commis- 

 sion, Southeast River Basins. This indicated 

 that the wildlife productivity potential of the 

 area, although not as yet fully attained, can 

 be expected to meet recreational needs of 

 the hunting public for many years in the 

 future. The review demonstrated the need 

 for more accurate inventory techniques of 

 game species. 



Biologists of the Denver Center studied 

 the relation of small mammal populations 

 to forest regeneration and range conditions, 

 the influence of showshoe hare and white - 

 tailed deer upon timber stand development, 

 and the effects on wildlife habitat of silvi- 



cultural practices and phytocide applica- 

 tions to forest and range lands. Most of 

 this work was done in close cooperation
