334 BiKDS OF i^oKTii Cakolina 



C. S. Brimley found it Ijreeding at Blantyrc, in early May, 1908, and Sherman 

 discovorod the species abundant at Blomng Rock in June, 1909. In May, 1908, 

 we also found it common and a])parently settlctl tlo\\ii to breed at Hendersonville, 

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

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

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

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



341. Planeoticus migratorius achrusterus (Batch.). Southern Robin. 



Smaller tlian migratorius, colors in general much lighter and duller. ^\'., 4.80; T., 3.C0. (Chap., 

 Bint.'i (,J K. N. A.) 



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



Range in North Carolina. — Central and part of tlie eastern eotmties in simimer. 



Tliis form, which is nothing nujrc than the extreme soutlieru 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. Potcat, 

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

 be especially partial to lawnis 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 Ai^il 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.

Pia. 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, l)ut just as frequently in situa- 

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