SYLVICOLTD-E — THE WARBLERS. 295 



A nest of this l)ir(l troin Chester Connie, Penn., is a very fiat struetuie, 

 evidently Iniilt in a heel ot' fallen leaves. It has a diameter <»f six inches and 

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

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

 woven a coarse linin*- of lonir, drv, and wirv mutlets and stems of idants. 

 It was given to ^Ir. J. P. Xorris, from wIkjiu I received it, and it is now in 

 the Boston collection. 



Mr. liobert liidgway furnislies the following valuable information in regard 

 to the abundance and geneml habits of this species 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 

 Sjieciesjandof terrestrial habits, like the Siiiirtis((Ui'oc(fjn/lus, but generally fre- 

 quents rather ditlerent situations from the hitter bird, liking better the under- 

 growth of ' bottom ' woods than that of dry forests. In all its mannei"s it 

 closely resembles the Seiuri, especially the two a([uatic species, ladovicianus 

 and noveboraccnsis, having the same tilting motion of the body, and horizontal 

 attitude when perching, so characteristic of these birds. The nest I have 

 never found, though 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 enaljle me to discover it. In most cases the nest is 

 prol)ably on the ground, among the rubl)ish of fallen tree-tops, or low brush- 

 wood. 



"The usual note of this Warbler is a sharp f>ihij), almost precisely like that 

 of the Pewee {Safioriiisfnscu>>), uttered as the bird perches on a twig near the 

 ground, continually 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, delivered very much in the stvle of the Cardinal 

 Grosbeak {Cardiaalix vuyi/tunias), though finer in tone, and weaker." 



Dr. Coues found this Warlder rare at Washington, and chiefly in low 

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

 not shv, and a few breed there.
