A nest of this liinl fro.ii Chester CounJ;^, 1*01111., is a very flat structure, 

 tiviilently Iniilt in a hed of fallen leaves. It has a diameter nf si.x inches and 

 a height of only two. The cup is a mere depression only half an incii in 

 deptli. Its base is loosely constructed of dried leaves, upon which is inter- 

 woven a coarse lining of long, dry, and wiry rootlets and stems of plants. 

 Tt was given to ^Ir. J. P. Norris, from whom I received it, and it is now in 

 the Boston collection. 



At 



Mr. liobort llidgway I'urnislies the following valuable information in regard 

 to the abundance and general habits of this sjjecies as observed in Southern 

 Illinois : " It is a very common summer bird in Southern Illinois, where it 

 arrives in the Wabash Valley towards the last of April. It is a wood-loving 

 species, and of terrestrial habits, like the Sciu/'ns inirunijii/lus, but generally I're- 

 queiits rather different situations froJii the latter l)ird, liking better the under- 

 growth of ' bottom ' woods tiian that of dry forests. In all its manners it 

 closely resembles the Sriitri, especially the two atpiatic species, liulovicianus 

 and novchoraccnsts, having tiie same tilting motion of the body, and horizontal 

 attitude when per(;hiiig, so characteristic of these birds. The nest I have 

 never found, thougii well aware of its -actual situation. I knew of one some- 

 where among the ' top ' of a fallen tree, but it was so well concealed that 

 the closest search did not enable me to discover it. In most cases the nest is 

 proljably on the ground, among the rubbish of fallen tree-tops, or low brush- 

 wood. 



" The usual note of this "Warbler is a sharp fnhiji, almost precisely like that 

 of the Pewee (Sai/or/n.'ifiiscn:<), uttered as tlie bird perches on a twig near the 

 ground, continnally tilting its body, or is changed into a sharp rapid twitter 

 as one chases another through the thicket. Their song is very pretty, con- 

 sisting of a fine whistle, ilelivered very much in the style of the Cardinal 

 Grosbeak (C'ltrduia/ia vinjini(inu>i), though finer in tone, and weaker." 



Dr. Coues found this \Varl)ler rare at Washington, and chiefly in low 

 woods with thick undergrowth, and in ravines. They were very silent, but 

 not shy, and a few breed there.
