Family SYLVIID^. Warblers. 



372. Polioptila plumbiceps Lawrence. 



PoHoptila nigriceps (not of Baird) Salvin and Godman, Ibis, 1880, 116 

 (Valencia; crit.). — Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 181 (Sal- 

 vin and Godman's reference). 



Polioptila sclateri Sharpe, Cat. Birds Brit. Mus., X,' 1885, 449 (Valencia). — 

 Sharpe, Hand-List Birds, III, 1901, 241 (" Sierra [Nevada] of Santa 

 Marta"). 



Polioptila nigriceps sclateri Hellmayr, Nov. Z06I., VII, 1900, 537, in text, 

 538 ("Santa Marta"; crit.). 



Twenty-five specimens : Rio Hacha and Valencia. 



These differ from a good series of Venezuelan specimens in averag- 

 ing whiter below, in which respect they, approach P. livida (Gmelin) 

 of Cayenne. The latter, however, has the tertiaries and rectrices much 

 more extensively white, and the greater wing-coverts margined with 

 white, while the primaries are wholly black, and not edged with gray, 

 as in the present form, which had best be kept specifically distinct. 



A fairly common bird around Rio Hacha, as well as in the valley 

 southeast of the mountains, frequenting all sorts of growth. It is very 

 restless in its habits, hopping continuously about in the branches in its 

 search for insects, and is not at all shy. The note is a faint, insect- 

 like chirp. 



373. Polioptila bilineata bilineata (Bonaparte). 



Polioptila bilineata Bangs, Proc. Biol. Soc. Washington, XII, 1898, 144 

 (" Santa Marta "). — Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 181 

 (Bonda). — Hellmayr, Verb, zool.-bot. Ges. Wien, 1903, 224 ("Santa 

 Marta," in range) .—Ridgw ay. Bull. U. S.' Nat. Mus., No. 50, III, 1904, 

 726 (Bonda and "Santa Marta," in range; references). 



Four specimens : Bonda and Fundacion. 



A rare bird in this region. Mr. Brown secured a single specimen, 

 taken probably near Bonda, and Mr.' Smith's collectors secured only 

 two. Although the writer has watched closely for the species in this 

 vicinity he has never succeeded in detecting it there. Three specimens 

 were taken at Fundacion, in August and October, 1915. They were 

 shot in open woodland, and in habits resembled P. plumbiceps.
