334 BIRDS OF !N"oRTH CAROLINA 



C. S. Brimley found it breeding at Blantyre, in early May, 1908, and Sherman 

 discovered the species abundant at Blowing Rock in June, 1909. In May, 1908, 

 we also found it common and apparently settled down to breed at Hendersonville, 

 Toxaway, Sapphire, Franklin, Aquone, and Andrews, and saw two on the top of 

 Joanna Bald Mountain. The nest is much like that of the Wood Thrush, only 

 larger, but the inner lining of mud is more extensive. The eggs are four in 

 number, of a greenish blue ground color, unspotted. Size about 1.16 x .80. 



341. Planeoticus migratorius achrusterus (Batch.}. SOUTHERN ROBIN. 



Smaller than migratorius, colors in general much lighter and duller. W., 4.80; T., 3.60. (Chap., 

 Birds of E. N. A.) 



Range. Southern States, limits of range not well known. 



Range in North Carolina. Central and part of the eastern counties in summer. 



This form, which is nothing more than the extreme southern variation of the 

 Robin, is found commonly breeding at Raleigh (C. S. Brimley), Chapel Hill and 

 Greensboro (Pearson), while at Wake Forest it is, according to Dr. W. L. Poteat, 

 the most common bird on the campus in summer. At all of these places it seems to 

 be especially partial to lawns and gardens. Other places from which it has been 

 recorded are Southern Pines, where C. S. Brimley found it abundant in late June, 

 1909; Gatesville, July 18, 1909, and Grimesland, Pitt County, July 30, 1909 

 (Sherman) ; and Belvidere, Perquimans County, where three pairs were seen nest- 

 ing on April 25, 1898 (Pearson). The southern limit of its range in North Caro- 

 lina is an interesting problem yet to be solved by students of bird-life.

PIG. 275. BLUEBIRD. 



The Bluebird is one of our most familiar birds, and nests everywhere in natural 

 hollows in trees, often in orchards or near houses, but just as frequently in situa- 

 tions remote from the haunts of man. The bottom of the hollow is lined with
