234 PASSERES : Perching Birds 



SAN CLEMENTE WREN 



(719.1. Thyromanes leucophrys) 5j in. 



Resembles the San Diego Wren, but much grayer above; 

 superciliary broader and whiter. 



WESTERN HOUSE WREN 



(721a. Troglodytes aedon parkmani) 4f in. 



Upper parts grayish brown; fine dusky barring on wings and 

 tail; light grayish below, dusky-barred on belly and under tail- 

 coverts. 



Absence of distinctive marks, visible at a distance, is this 

 bird's "field mark." Add to this his almost constant, bubbling 

 song (in nesting-season), and his identification is complete. 



WESTERN WINTER WREN 



(722a. Nannus hi emails pacificus) 4 in. 



Dark brown above; tawny below, sides and belly dusky- 

 barred; sides of neck gray-speckled; an indistinct tawny super- 

 ciliary. 



In the field: A very small, thick-bodied, stubby-tailed, brown 

 bird, creeping mouse-like through brush-heaps or under build- 

 ings, and uttering the Song Sparrow " chimp." 



TULE WREN 



(725a. Telmatodytes palustris paludicola) 4 in. 



Brown: middle-back black, white -streaked; top of head black- 

 ish; indistinct superciliary; tail broadly black-barred above; 

 under parts lighter, whitening on breast and throat. 



Compare Western Marsh Wren, found in same locality in 

 winter. 



Nest a ball of tightly woven marsh grass, binding together 

 several tule stalks, with opening often concealed. 



WESTERN MARSH WREN 



(725c. Telmatodytes palustris plesius) 5i in. 

 Like the Tule Wren, but larger, and lighter throughout except 

 black-and-white markings of back; top of head brown; super- 

 ciliary broader and better defined; tail barring much finer.
