In the beginning of my study of bird life, when I had a bird-room for close observation, I was interested to see that our little neighbors in feathers possess as much individuality of character as ourselves, and in Chapters XII. and XIII. of this volume I offer two studies of that period, illustrative of the point.

Thanks are due to Mr. Frederic A. Ober for the use of his notes on one of the solitaires, embodied in Chapter XII., and to the Godey Company for permission to reproduce two shrike pictures.

I wish also to give credit to my daughter, Mary Mann Miller, for the minute and conscientious collection of the facts recorded in Chapters V. and VI., which for convenience are related as if they were my own observations.
