TROGLODYTES GRENADENSIS (Lawrence). 

 GRENADA WREN. 



Similar in large size to T. martinicensis, but upper parts much 

 brighter, more tawny, brown, flanks deeper rufous-cinnamon or cin- 

 namon-rufous, and under tail-coverts plain cinnamon-rufous; similar 

 in coloration to T. rufescens, but wing and bill longer and tail shorter, 

 and coloration decidedly lighter; similar in coloration of upper parts 

 to T. mesoleucus, but without white on under parts. 



Adults {sexes alike). — Above plain rufous-brown (between russet and 

 mars brown), brighter (approaching burnt-umber) on rump and upper 

 tail-coverts, duller on pileum; greater wing-coverts narrowly and 

 I'ather indistinctly barred with dusky, the secondaries and tail nar- 

 rowly and distinctly barred with blackish; primaries more broadly 

 barred with blackish, their terminal portion plain dusky; a rather dis- 

 tinct superciliary stripe of cinnamon-buff; lores and eyelids similar 

 but more whitish; sides of head otherwise light cinnamon-buff, more 

 or less (always indistinctly) flecked and streaked with brown, the 

 upper portion of auricular region mostly brown, forming an indistinct 

 postocular streak; chin and throat pale cinnamon-buff, deepening on 

 chest into deep cinnamon-buff, the remaining under parts still deeper 

 in color, the sides, flanks, and under tail-coverts russet; under tail- 

 coverts sometimes immaculate, usually with more or less distinct bars 

 or spots of dusky on terminal portion of the longer feathers; maxilla 

 dusky brown, with paler tomia; mandible dull light yellowish (in dried 

 skins); legs and feet light brownish (in dried skins). 



Young. — Similar to adults, but feathers of chest very faintly mar- 

 gined terminally with dusky, and under tail-coverts always immaculate.
