260 NORTH AMEKICAX BIRDS. 



near Fort Steilacoom, generally met with ou oaks, and very niiicli resembling 

 De7idroica muluhuni in its li;il)its. Its arrival there he gives as occurring 

 in the first week in April, or a mouth earlier than stated by Nuttall. 



Dr. Cooper met with a pair at Paget Sound that appeared to have a nest, 

 though he sought for it in vain. He describes its note as faint and unvaried. 



Dr. Cones met with this Warbler in the vicinity of Fort Whipple, Arizona. 

 He speaks of it as common there as a sjiring and autumn migrant. He thinks 

 that a few remain to breed. It arrives in that Territory about A]>ril 2(1, and 

 is found until late in Sejitember. It is most common among the pine-trees, 

 and in its general lialjits is stated to resemble the new species B. (jraiyim. 



Dr. Heermanu found a few 1)irds of this species near Sacramento, and also 

 on the range of mountains dividing the Calaveras and the Mokelumne Elvers. 

 During the survey by Lieutenant Williamson's party, Dr. Heermanu met 

 with a single specimen among the mountains, near the summit of the Tejon 

 Pass. It was in company with other small birds, migrating southward, and 

 gleaning its food from among the to])most branches of the tallest oaks. He 

 states that its notes closely resendjle the sounds of the locust. 



Dr. Cooper states that these birds ajjpear at San Diegoby the 20th of 

 April, in small flocks migrating northward, and then uttering only a faint 

 chirp. They fre(juent low bushes along the coast, but as they proceed farther 

 north they take to the deciduous oaks as the leaves begin to expand, early 

 in May, at which lime they reacli the ('olumbia lliver. He has never met 

 with any in California after Ajiril. 



j\Ir. Kidgway observed this species only in the i)ine and cedar woods of 

 the East llundioldt Mnuntains, where, in all ]irol)ability, they were breeding. 

 He observed nunu^i'nus I'amilies of young bii'ds following their parents in 

 the months of July and August. He met with them only among the cedars 

 and the woods of the nut-pine, and never among the brushwood of the canons 

 and ravines. He states that the common note of this bird greatly resembles 

 the sharp chirp of the Dendroica coronata, and is louder and more distinct 

 than that of D. audv.honi. 



Mr. A. Boucard obtained specimens of those birds at Oaxaca, Mexico, 

 duriu" the winter months.
