PREFACE. 
The following list contains the names of the birds of the 
Connecticut-Valley in Massachusetts, so far as they are known 
to the authors, either by personal observation or from consult- 
ing the works of the ornothologists who have described the 
birds of New England. 
The works of Allen, of Baird, Brewer and Ridgway, of 
Coues, of Minot, of Samuels and of Stearns have been freely 
used. We have also availed ourselves of the experience of 
such collectors as E. O. Damon of Northampton, Bradley 
Horsford and O. B. Deane of Springfield. 
The nomenclature is that adopted by the American Orni- 
thologists’ Union, and the numbers attached to the names in 
this list correspond to the numbers in the ‘‘ Check-list of North 
American Birds,”’? published by the Union in 1889. Mr. Morris 
has had the supervision of that part of the list which contains 
the birds of prey and the waterbirds, and Mr. Colburn has had 
charge of the remainder of the list. 
We do not claim that the list is perfect. Further observa- 
tion will doubtless necessitate changes in the direction of 
addition, if not of elimination. 
Although we have prepared this list for our own use, and 
not for general publication, we shall have a few copies, which 
we will gladly give to any one who may desire to obtain them.
