566 GEOLOGICAL SURVEY OF NEW JERSEY. 



THRYOTHORUS, Vieill. 



T. ludovicianus, Lath. Carolina Wren. 



Reddish brown above, brightest on rump ; whitish superciliary- 

 stripe, bordering a blackish stripe ; wings narrowly barred with 

 dusky ; pale rusty spots on quills ; chin whitish ; lower parts 

 tawny. Length, 6 inches ; tail, 2J inches. 



" Rare, and frequenting secluded, tangled thickets. Is but 

 seldom met with, even when several may be in the seeker's 

 neighborhood. Have seen them only in Camden county." 

 [C. C. A.] 



T. bewickii, Aud. Bewick's Wren. 



Grayish brown ; two middle tail feathers barred. Length, 5| 

 inches ; tail, 2| inches. Belongs to the south and eastern portion 

 of the Mississippi Valley. 



" Like the above, this wren is but seldom met with in New 

 Jersey. Appears to be more abundant, however, during some 

 seasons than during others." 



TROGLODYTES, Vieill. 



T. aedon, Vieill (domesticus, Bartr.) House Wren. Wood Wren. 



Color brown ; brightest behind ; rusty below ; everywhere 

 more or less waved, with darker, especially on the wings, tail, &c. 

 Very variable. Length, 5 inches ; tail, 2 inches. 



"Arrives early in May, and is everywhere abundant, unless it 

 be in dark, unfrequented swamps, for the wren is eminently a 

 social bird, and intelligent above many of its race. Builds in 

 boxes erected for his accommodation, in deserted woodpeckers' 

 nests anywhere that affords a certain amount of shelter. Ten 

 eggs are frequently laid, eight always, and two broods are gener- 

 ally raised. Feeds exclusively upon insects, and is as active in 

 their destruction as any of the 'flycatcher' tribe. Have all 

 disappeared by October 15th." 



The following is doubtless a mere variety : 



" Troglodytes americanus [Abbott's Catalogue]. Wood Wren. 



"In all respects, in plumage, movements, and habits generally, 

 is similar to the preceding species, but inhabits the unfrequented 

 woody districts. Arrives and disappears with the aedon."
