236 NORTH AMERICAN BIRDS. 



the pectoral collar; one (No. 60,877, Mt. Carmel, Wabash Co., 111., Aug. 9) 

 has this entirely interrupted. In this individual there is no trace of a 

 whitish supra-auricular streak ; while others from the same locality, and 

 obtained at the same date, Iiave the band across the jugulmu continuous, and 

 a quite distinct wliite streak over the ear-coverts. 



H-iBiTS. Of this somewhat rare Warbler very little is as yet well known. 

 Its habits and distribution during the breeding-season need more light than 

 we now possess to enable us to give its story with any degree of exactness. 

 Its appearance in Peuusyh-ania, Ohio, Illinois, and Missouri early in May, 

 when Warblers that go north to breed are on their way, at first suggested its 

 belonging to that class. It is not known to proceed any farther north, ex- 

 cept in accidental instances ; though the writer has been assured, and has no 

 reason to doubt the fact, that it abounds and breeds in the neighborhood 

 of Niagara I'alls. I can find no good evidence that it ever occurs in Massa- 

 chusetts. Individuals have been obtained in northern South America, Pana- 

 ma, and Cuba. l)r. Woodhouse describes it as quite common in Texas and 

 in the Indian Territory, where it breeds, as he obtained both the old and the 

 young birds. It was also abundant among the timbered lands of the Arkan- 

 sas and its tributaries. It was not obtained in any other of the government 

 expeditions, nor was it found in Arizona by Dr. Coues. j\Ir. T. M. Trippe 

 noticed a single individual near Orange, N. Y. Wilson supposed them to 

 breed in Pennsylvania, though he was never able to find their nests. He 

 usually met with these birds in marshes or on the Ijorders of streams among 

 the branches of ])0])lars. Tlieir haliits were those of the Flycatcliers. He 

 saw none later than the 20th of August. Describing this species as the Blue- 

 green Warbler, as met with by him on the banks of the Cumberland early in 

 April, he mentions its gleaning for food among the upper brandies of the 

 tallest trees, rendering it difficult to be procured. Its resemblance, in liabits, 

 to Flycatchei-s, he again remarks. Its only note was a feeble cheep. 



According to Audubon, this Warbler appears in Louisiana, where it also 

 breeds early in spring, and leaves tlie first of October. Like all its family, it 

 is quite lively, has a similar Jlight, moves sideways up and down the branches, 

 and hangs irom the ends of the twigs in its search for insects. 



Mr. Audubon also states that the liveliness of the notes of this Warbler 

 renders it consi)icuouR in tlie forests, the skirts of which it frecj^uents. Its 

 song, though neither loud nor of long continuance, he speaks of as extremely 

 sweet and mellow. He found it as numerous in the State of Louisiana as 

 any other Warbler, so that he could sometimes obtain five or six in a single 

 walk. 



The nest he describes as placed in the forks of a low tree or bush, partly 

 pensile, projecting a little above the twigs to which it is attached, and ex- 

 tending below them nearly two inches. Tlie outer part is composed of the 

 fibres of vines and the stalks of herbaceous plants, with slender roots ar- 

 ranged in a circular manner. The nest is lined with fine dry fibres of the
