330 WILD WINGS

 shutter did not seem to alarm her, she was not quite ready 

 to brave the camera, so she flew, and it was not until the 

 third approach that she actually alighted on the nest and 

 went to brooding. All this had taken her a little over an 

 hour. I did not attempt as yet to change the plate, wishing 

 her to learn that the camera was harmless. She remained 

 seven minutes over her young, and then flew off of her own

Just after her first approach to the nest, her mate for the

 only half the owl was upon the plate, the camera having 

 moved, and in the others the bird was more or less hidden 

 by the branches. 



On the fifteenth of April I made the trip again, this time 

 alone. It was quite mild and bright. Only patches of snow-
