PANAMA BLACK-BILLED WREN 



FIG. 87. Thryophilus modestus elutus 



throat, chest, breast and abdomen white, the 

 abdomen more or less tinged with buff. 

 Young. Similar to adults. 



Very common, especially so in the semi-arid 

 and brushy regions of the Pacific side of the 

 Isthmus ; recognizable among the larger wrens of 

 the Canal Zone by its rather dull colors. Its 

 song is loud and varied, consisting of trills and 

 high pitched whistles, some of them suggesting 

 in their tone the notes of the Water Thrushes 

 (Seiurus) ; one of its common ones is a phrase of 

 four loud whistled notes, repeated several times 

 in close succession.
