NO. 2 BIRDS OF ISLA ESCUDO DE VERAGUAS — WETMORE 23 



Family Parulidae: Wood Warblers 



DENDROICA PETECHIA ERITHACHORIDES Baird: Golden Warbler, 

 Canario Manglero 



Dcndroica erihtachorid.es (= erithachorides, typographical error, corrected in 

 index) Baird, Report of explorations and surveys . . . for a railroad from 

 the Mississippi River to the Pacific Ocean, vol. 9, pt. 2, Birds, 1858, pp. 283, 

 976. (Cartagena, Colombia.) 



These warblers (fig. 3) were found scattered through the taller 

 trees where they were fairly common, though each of the four taken 

 appeared to be alone. It should be noted that on Escudo they were not 

 restricted to the limited growths of mangroves found near the sea, as 

 is the case on the mainland, but ranged throughout the forest growth, 

 as appears to be the regular habit of this warbler when found on small 

 islands. On the present island they ranked third in abundance among 

 the smaller land birds. The four taken include three adult males which 

 are similar to a small series from the shores of Almirante Bay on the 

 nearby mainland. A female that had just begun the molt from the 

 gray juvenile dress to the yellow adult plumage had the skull fully 

 ossified, indication that this character as a criterion of age is not re- 

 liable in tropical areas, where the life cycle of an individual bird is not 

 necessarily arranged on a calendar year basis. 



The series from Escudo and from Almirante Bay agree fully with 

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

 Limon, Costa Rica, about 100 kilometers to the north, are Dendroica 

 p. bryanti. 



Family Thraupidae: Tanagers 

 THRAUPIS VIRENS (Linnaeus): Blue-gray Tanager, Azulejo 

 Loxia virens Linnaeus, Systema naturae, ed. 12, vol. 1, 1766, p. 303. (Surinam.) 

 Blue-gray tanagers were fairly common in the taller trees, a num- 

 ber being seen and three collected. It has been unexpected to find that 

 they are so different from the widely distributed race of the mainland 

 that they merit description as an additional subspecies. 



THRAUPIS VIRENS CAESITIA subsp. nov. 



Characters. — Similar to Thraupis virens diaconus (Lesson) 3 but 

 darker, particularly below; central lower surface nearly uniform in 

 shade from throat to under tail coverts ; sides definitely darker ; bill 

 longer and heavier.
