STLYICOLID^ — THE WARBLERS. 237 



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

 dish spots about the largei' end. When distm-bed during incubation, the 

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

 notes, in the manner of I), ccstiva. After the young have left the nest, they 

 move and luiut together, iu 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 tliickly covered with grapevines, and to occa- 

 sionally alight on tall weeds, feeding upon their seeds. 



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

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

 flock on a small island. 



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

 also iu West Florida. 



In only a single instance has the -m-iter met with this Warbler. This was 

 about the middle of June, at the Fairmount "\\'ater Works in tlie city of Phila- 

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

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

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

 with great agdity. 



Mr. Ridgway gives the Cferulean Warbler as the most abimdant species 

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

 I'all migrations, l)ut also in the summer, when it breeds more plentifully even 

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

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

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

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

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

 feeble notes.
