74 GEOTHLYPIS TRICHAS, MARYLAND YELLOW-THROAT. 



Mississippi Valley beyond the Missouri, where Dr. Hoy found it in great 

 ahuiulaiice in the western part of the State. He says: "They live and 

 nest in the underbrusli, the male occasionally hopping upon a low branch 

 of a tree to pour forth his whittishee, ivhitfifihee, repeated two or three 

 times, then disapi)earitig in the tangled brush. This song is so precisely 

 like That ot the Yellow-throat, that it requires a practiced ear to distin- 

 guish the one from the other." 



The nest, says Audubon, "is small, beautifully constructed, and 

 usually attached to several stems of rank weeds. The outer parts are 

 formed of the bark of stalks of the same weeds, in a withered state, 

 mixed with a tiner kind, and some cottony substances. It is beautifully 

 lined with the cottony or silky substance that falls from the cotton-wood 

 tree. The eggs are from four to six, of a pure white color, finely sprink- 

 led with bright red dots." Tuo nests before me, taken early in June, in 

 Georgia and Kansas, respectively, differ somewhat from such a one as 

 Audubon describes. One of them appears to have lost an outer part it 

 probably had ; the other, comi)lete, is a large bulky structure, five or 

 six inches across, composed externally of a mass of dried leaves and 

 small sticks; the lining is of fine rootlets. The eggs are as Audubon 

 says — the fine dotting occurs sparsely all over the surface, but most 

 thickly at and around the larger end, and brsides the reddish sprinkling 

 there are other dots of neutral tint. Dimensions 0.G8 by 0.55.
