BACHMAN'S SPARROW 



Though technically considered a subspecies, Bacljnian's Sparrow (Peucaa 

 astivalis hachmani) has a wider distribution and is better known than the type 

 species, the Pine- woods Sparrow {Peucaa (Bstivalisr^stivalis) . The latter is 

 only slightly migratory, breeding in a restricted area from southern Georgia 

 to central Florida, and wintering from the southern part of the breeding-grounds 

 to southern Florida. It is probable that the short migration journey is pi^ 

 formed in late February and early March, and by the end of this latter month 

 the species is settled in its summer home. 



Bachman's Sparrow is an example of a bird that is apparently extending 

 its range. Within recent years it has become common locally in southern 

 Virginia, and has increased around Washington, D. C, until it is now known 

 in four localities. It has invaded Ohio, even to the northern part of the state, 

 and also western Pennsylvania. The more northern breeding individuals are 

 strictly migratory, while from eastern Texas to northwestern Florida the birds 

 are present throughout the year.
