Distribution. The Evening grosbeak inhabits boreal North America, 

 breeding in western Alberta and the surrounding country; and winters 

 from southern Saskatchewan to Missouri, Kentucky, Ohio, and irregularly 

 to New England, New York and Pennsylvania. When I began to study 

 the migration and distribution of New York birds, I supposed that only 

 one visitation of the Evening grosbeak had ever occurred in New York 

 State, namely, the great invasion of 1890, when these birds were found 

 in almost all the northeastern states in considerable abundance; but on 

 further investigation I find that it has occurred almost certainly on all 

 the following dates: 1875, 1882, 1886, 1887, 1889-1890, 1896, 1899, 1900, 

 1904, 1906, and another large visitation in 1910-1911. Thus this bird 

 must be considered as an occasional winter visitant in recent years, but 

 usually in very small numbers, especially when the seed crop in the north- 

 west has failed. 



Haunts and habits. With us it feeds on seeds and buds of the maple, 

 ash, mountain ash and various fruits which are left hanging on the trees. 

 This interesting species, which is related to the Hawfinch of Europe, is
