SYLVICOLID^E — THE WARBLERS. 237 



Spanish moss. The eggs are five in number, of a pure white with a few red- 

 dish spots about the larger end. When disturbed during incubation, the 

 female is said to trail along the branches with drooping wings and plaintive 

 notes, in the manner of D. cestiva. After the young have left the nest, they 

 move and liunt together, in company with their parents, evincing great activ- 

 ity in the pursuit of insects. They are also said to have a great partiality 

 for trees the tops of which are thickly covered with grapevines, and to occa- 

 sionally alight on tall weeds, feeding upon their seeds. 



In his visit to Texas, Mr. Audubon met a large number of these birds 

 apparently coming from Mexico. On one occasion he encountered a large 

 Hock on a small island. 



Mr. Nuttall mentions finding these birds very abundant in Tennessee, arid 

 also in West Florida. 



In only a single instance has the writer met with this Warbler. This was 

 about the middle of June, at the Fairmount Water Works in the city of Phila- 

 delphia, where, among the tops of the trees, a single individual was busily 

 engaged in hunting insects, undisturbed by the large numbers and vicinity 

 of visitors to the grounds. It kept in the tops of the trees, moving about 

 with great agility. 



Mr. Eidgway gives the Cserulean Warbler as the most abundant species 

 of its genus in the Lower Wabash Valley, not only during the spring and 

 fall migrations, but also in the summer, when it breeds more plentifully even 

 than the B. wstiva. It inhabits, however, only the deep woods of the bot- 

 tom lands, where it is seldom seen, and only to be distinguished by the nat- 

 uralist. Inhabiting, mostly, the tree-tops, it is an inconspicuous bird, and 

 thus one that easily escapes notice. In its habits it is perhaps less interest- 

 ing than others of its genus, being so retired, and possessing only the most 

 feeble notes.
