RECAPITULATION. Ill 



V— RECAPITULATION. 



The birds included in the preceding catalogue are now presented in 

 categories to show at a glance those which are permanent or summer 

 or winter resideuts, and those which are regular or accidental visitants. 

 It is somewhat difficult to make out such a recapitulation, from the fact 

 that of some species undoubtedly to be classed as spring and autumn mi- 

 grants, a few individuals breed or pass the winter ; while, of those which 

 regularly pass the summer or winter with us, many are more abundant 

 in spring and fall. We have endeavored to place each species in the 

 category to which it most naturally belongs, indicating also various 

 irregularities in brief words. 



The additions made to each category since 18G2, and the few trans- 

 fers from one to another category, are also indicated at the end of each 

 list. 



We also note, but do not enumerate, in Category F, some twenty-five 

 species which we suppose, from what is known of their general distri- 

 bution, will eventually be detected in the District.
