In writing of this species as observed by him in Ritchie County, 

 West Virginia, Mr. Brewster says: 



" Decidedly the most abundant of the genus here. The first speci- 

 men taken May 5. They inhabit cxc-hiMvch the tops of the highest 

 forest trees, in thi* n-sjHTt showing an affinity with I). lilurktinrniii'. 

 In actions they most resemble D. fMMyfMMHM^ carrying the tail 

 rather high and having the same 'smart bantamlikc appearance.' 

 Were it not for these prominent characteristics they would be very 

 difficult to distinguish in the trot- tops from I'dniln [= Cninjmothlyinx] 

 americann, the songs are so precisely alike. That of the latter bird 

 has, however, at least two regular variations: in one. beginning low 

 down, he rolls his guttural little trill quickly and evenly up the scale, 

 enilin^ apparently mily when he can get no higher: in the other the 

 cDinmencrmrnt <>f this trill is broken or divided int syllables, like *, 

 let, tee, ze-rt-tf-rf/i. This latter variat inn is the one used by J). rtrrulea, 

 and I i-i.iilil d.-ti-ct little or no difference in the songs of do/ens <>f in- 

 dividuals. At U-t it io a mildest little strain and far from deserving 

 the etic.imiiim bestowed U|MU it by AuilulH>n, who des<-ril)es it as 'ex- 

 tremely sweet and mellow'; decidedly it is neither of these, and he 

 must have confounded with it s.me other >jH-cies. In addition to the 

 pong they utter the almost iiiiivi-r-.il Oendroicinc lisp and also the 

 characteristic tchrp of D. rornutn. which I had previously supposed 

 entirely |>eculiar to that bird."
