MACGILLIYRAT’S SHORE-FINCH.

another on wing, but usually abandons the chase before the conquered bird 
has alighted, leaving it to pursue its course as it pleases after it has been 
driven beyond the assailant’s jurisdiction. The notes of this species are 
few and unmusical, consisting of a sort of roll of five or six syllables, which 
it seems to me impossible to imitate. They are usually heard early in the 
morning. My friend Dr. Bachman informs me that none of these Finches 
remain in South Carolina during winter,, and that they generally disappear 
early in November, when the weather is still very pleasant in the maritime 
portions of that state. Many, however, spend the winter in the salt marshes 
about the mouths of the Mississippi, and I have no doubt that they are con- 
stant residents there, as they are in the Texas. 
Abundant in Texas and along the Gulf of Mexico. Rather rare in South 
Carolina, from which it migrates in autumn.
