■ The Brown-headed Nuthatch {S. puxilla), is a species belonging to 

 the Southern States, where it is abundant from Louisiana and 

 Florida to lower Maryland. It has been taken in the vicinity of 

 St. Louis, Missouri, and also in Michigan and Ohio ; therefore, its 

 presence in the southern part of Illinois, especially among the pine 

 woods which there occur in certain localities, is to be anticipated.
