THRYOTHORUS, Vieill. 



T. ludovicianus, Lath. Carolina Wren.

 stripe, bordering a blackish stripe ; wings narrowly barred with 

 dusky; pale rusty spots on quills; chin whitish; lower part& 

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



T. bewickii, Aud. Bewick's Wren. 



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

 inches ; tail, 2 J 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 thei 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 americanua [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."
