 able of all the species of the family which occur within the United 

 States. It is decidedly the finest songster of all those which reach

 may be regarded as the most abundant species of its family. This 

 experience accords with that of .\udubon and Wilson; but the habits 

 of birds vary greatly with locality, and in other portions of the 

 country, notably in New England, it is said to be a very familiar 

 species, delighting in the companionship of man,
