The Warbler Book 63 



to it? How long after leaving the nest do the young birds remain under 

 the care of the parents? How do the parents endeavor to protect the 

 young? By scolding, direct attack, or feigning lame, etc. Have the 

 young any characteristic calls? Is more than one brood reared in a season? 



The writer earnestly hopes that he will receive the active cooperation of 

 bird students in securing information regarding the habits of Warblers, 

 along the lines suggested above. Do not neglect sending your observations 

 because they are incomplete. Every fact will be welcomed and full credit 

 will be given for all material used. Let us make this book of the Warblers 

 a thoroughly representative and satisfactory piece of work, and lose no op- 

 portunity during the coming nesting season to add to our knowledge of 

 these birds. 



Bird Lists of the Massachusetts Audubon Society 



In order to encourage systematic observation on the part of its members, 

 the Massachusetts Audubon Society supplies them with check -lists of birds, 

 with blanks to fill in the locality and date at which the species noted was 

 seen or heard. 



The best ten lists covering the period from January i, 1903, to January 

 I, 1904, which have been returned to the secretary of the society, were 

 prepared by the following observers: Pupils Tarbell Grammar school, 92 

 species; Louise Howe, 94 species; Catharine Cravath Whitaker, 100 spe- 

 cies; James Lee Peters, lOi species; Samuel D. Robins, 107 species; 

 Lilian Cleveland. 117 species; Elizabeth S.Hill, 120 species; Richard M. 

 Hunt, 128 species; Isabel B. Holbrook, 132 species; Lilian E. Bridge, 156 

 species. All these lists are based on observations at several localities. The 

 highest number of birds recorded from one place is eighty by Edwin 

 Leonard, at Feeding Hills (Agawam). Mr. Leonard writes that all but 

 one of these were seen or heard on his own premises, mostly about his 

 house.
