grasses, moss, lichens, feathers, hair and other soft materials is usually placed 

 in a hole of some tree or stump. Not infrequently, however, the deserted holes 

 of squirrels or the old nests of crows and magpies are selected. 



The European Crested Titmouse would be a popular bird and much better 

 known were it not for the difficulty of studying the habits of so small an object 

 in the dense and extensive forests which it frequents. Its characteristics can 

 only be satisfactorily observed when it is compelled to seek its food in more open 

 places.

What true bird lover is there who does not cherish fond memories of cer- 

 tain birds? The very name of black-throated green warbler carries me back 

 to boyhood days and to a certain pine-crested hill in Massachusetts, from which 

 was wafted on an early spring morning the song of this warbler, heard by me 

 then for the first time. The many years since elapsed have not effaced the 

 sweet strains, and I seem to hear them now as they were borne that m.orning 

 by the pine-scented spring breeze. I can vividly recall the pleasure the song 

 occasioned and the satisfaction of having added one more bird to my small list 

 of avian acquaintances. Those were the days of mystery, when the woods 

 seemed filled with unknown birds, and secrets lurked in every thicket and met 

 the seeker at every turn. They were the times when bird books were fevv, keys 

 unknown, and the keen eyes of youth far more satisfactory than the best field 

 glasses of the present day. 



The black-throated green is one of the commoner of our eastern warblers 

 and one of the first to engage the attention of the bird student. During migra- 

 tion it may be met with in every kind of woodland, where it is at home, both 

 high and low, ever pursuing with tireless energy its quest for insects. It has 

 two songs, or rather one song delivered in two different ways, sprightly, sweet, 

 and perfectly charactertistic. In summer it is partial to coniferous woods, es- 

 pecially white pines and hemlocks, and it frequently nests in these, though also 

 in birches and alders.
