Bird Banding in Northern Michigan 87 



Station on Douglas Lake during July and a part of August, 

 1920, at which time he had charge of the work in Ornithol- 

 ogy at the Biological Station. The Douglas Lake region 

 offers many favorable habitants for nesting birds. Suit- 

 able nesting sites are present in great variety, food is 

 plentiful and the habitations of man are comparatively few. 

 However, it was surprising to discover the extraordinary 

 mortality among young birds due to what we may term 

 natural causes. In all probability our attention should 

 not have been called to this as well as to many other in- 

 teresting and instructive facts concerning young birds had 

 it not been for the intimate contact experienced while band- 

 ing these birds in the nest. For the students, the banding 

 seemed to lend added interest and zest to their bird study 

 work and they were the more easily encouraged to be on the 

 alert for something new and different. Additional oppor- 

 tunity was thus given for observation and study on be- 

 havior, nesting sites, nest materials, etc., all of which 

 afforded the student a wealth of first-hand knowledge as 

 well as created interest in the marking of the birds them- 

 selves. 



As a result of our activities which extended over a 

 period of six weeks, a total of 115 birds belonging to 20 

 different species were banded. 106 of these represented 

 nestlings occupying 39 nests; eight others were young 

 birds which were captured after leaving the nest and the 

 additional one was an adult bird.
