l>r. Cooper met witii a pair at I'uget Sound that apjieared to have a nest, 

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

 Dr. ( '(UK'S met witi, this AVarl.Ier in tiie vieinity of Fort Whipple, Arizona. 

 He spi'aks of it as cummon there as a spring and autunni migmiit. He tiiinks 

 that a W\\ remain to breed. It arrives in tliat Territory about Ajn^i] I'D, and 

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

 and in its geneml Jiabits isstate.l to rescnuble tlie new .sjiecies />. ,ir,„Uv. 



Dr. Jleermann tbund a lew birds of this species near Sacramento, ami also 

 on the range of luountaius (livi.ling the Calaveras and the Mokelunnie Itivers. 

 During the survey by Lieutenant Williamsons j.arty, Dr. Heerniann met 

 with a single s])ecinieu among the mountains, near the summit of tiie Tejon 

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

 gleaning its food from among the topmost lu'anclies of the tallest oaks. He 

 states that its notes clo.sely resendile the sounds of the locust. 



Dr. Cooper states tliat tiiese birds ajipear at San Diego by the 20th of 

 April, in small Hocks migrating northward, and tiieu uttering onlv a faint 

 chirp. They frequent low bushes along the coast, l)ut as they pit:)ceed farther 

 north they take to the deciduous oaks as the leaves begin to ex])antl, early 

 in May, at which time they reach the Columbia Kiver. He has never mc!t 

 with any in ( 'alifornia after April. 



Mr. Hidgway ob.served tliis species only in the pine and cedar woods of 

 the Kast Humboldt ]\Iountains, where, in all probability, they were breeding. 

 He observed numerous families of young birds following "their parents in 

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

 and the woods of the nut-pine, and never among thc^ brusiiw<.od of the canons 

 and ravines. He states tliat the common note of tiiis bird greatly resembles 

 the siuu'p chirj) of the Diiuhvici roronafa, and is louder and more distinct 

 than that of D.diiilulxmi. 



y.h\ A. Houcard obtained s])ecimens of these birds at Oa.xaca, Mexico, 

 during the winter months.
