in spring and fall, and is not of much economic value here ; 

 therefore, its description is omitted. The other species of 

 the ftimilj will l)e considered here, for they all frequent 

 meadows, grass fields, or cultivated lands. 



The Bronzed Grackle and the Purple Grackle are both 

 found in the State, but, as they are alike in form, notes, and 

 habits, they are both known as CroAV Blackbirds, and will 

 not be treated separately.
