107. Ornithology. — In this course, birds are studied mostly dur- 

 ing their breeding season, but in the latter part of the session, there 

 are opportunities for studying early autumnal migration movements. 

 Special attention is given to identification of birds and methods of 

 field study. Bird behavior and especially nesting habits are consid- 

 ered. Lantern slides are used in studying identification characteris- 

 tics and for illustrating bird behavior. The bird fauna is ample for 

 the course, and it is interesting especially because of the northern 

 species breeding here under wild conditions. There are conferences 

 at which various ornithological topics are discussed.
