material of this race, which is interesting since specimens from Limon, 

 Costa Rica, about 100 km to the north belong to the race D. p. bryanti. 



DENDROICA PETECHIA JUBARIS Olson 



Dendroica petechia jubaris Olson, 1980, Proc. Biol. Soc. Wash., 93(2), p. 478. 

 (Nuqui, Dept. Choco, Colombia, 5°40'N.) 



Characters. — Compared with aequatorialis, male with brown portions 

 of plumage lighter, more tawny; throat and chin either suffused with, 

 or distinctly streaked with yellow; cheeks and lores suffused with yel- 

 lowish, contrasting with the darker crown, so that birds appear dis- 

 tinctly capped, as opposed to aequatorialis, in which the entire head is 

 brown; belly less streaked with brown, appearing more brightly yellow. 



Measurements. — Males ( 10 from Darien and Colombia) , wing 60.6- 

 67.5 (65.0), tail 45.6-50.8 (48.5), oilmen from base 11.4-14.0 (12.9), 

 tarsus 17.9-19.8 (19.2) mm. 



Females (10 from Darien and Colombia), wing 56.9-64.7 (61.0), 

 tail 42.9-50.0 (46.1), oilmen from base 11.7-13.6 (12.3), tarsus 17.2- 

 20.1 (18.8) mm. 



Resident. Found in mangroves on the coast of Darien and south 

 along the Pacific Coast of Colombia, at least to Buenaventura, Valle del 

 Cauca. In March and April of 1946 I found them common at Jaque, 

 Darien. Males were singing and in breeding condition. In ascending 

 the Rio Jaque I noted that the Yellow Warblers were found only where 

 there were mangroves. 



Eisenmann noted 2 chestnut-headed birds on March 29, 1967, at Isla 

 Boca Grande in the upper Gulf of San Miguel, Darien, but most of the 

 Yellow Warblers seen there appeared to be of the migratory aestiva 

 group.
