THIS Blackbird is essentially a bird of the Prairies, and it is eminently fit- 

 ted for obtaining its living on the ground, since its legs and feet are strongly de- 

 veloped as if by and for scratching. Large numbers spend the winter sociably 

 in the tule swamps of Texas and California, breaking up into smaller companies 

 after the migration has been accomplished, and distributing themselves among 

 the inland marshes of the Great Plains, and locally throughout the West, where 

 they breed much after the fashion of Redwings. The species is of a rather 

 roving disposition, one specimen having been taken in Greenland in 1820. 

 Small bunches have several times been recognized on the wing by competent 

 observers here in Ohio, and Wheaton cites the instance of a pair being seen in 

 a low meadow near Groveport, in Franklin County, where it was thought to 

 have bred, in the summer of 1873.
