588 XOIiTH AMERICAN P'HDS. 



The type skin of Jtnno dorsal ui of Dr. Henry (see foot-note to synoptical 

 t;il)le, p. 580) (litters mainly in having tlie whole upper inunclible entirely 

 bliick, as in J. cine/rus ; luul, as in the latter, the juguluni is pale ash, fading 

 gradually into the white <»f the abdomen, instead of deep ash abruptly de- 

 fined. It is Aery prt)bably, as suggested by Mr. Hidgway, a hybrid witli 

 J. cinercus. 



Habits. Tliis species was first discovered and descri))ed by Dr. Wood- 

 house from specimens oi)tained by him anmng the San Francisco Mountains 

 in Arizona. Wlien procured, it was feeding in com))any witli tlie J unco ore- 

 (jonv^ and various species of Paras. Its hal)its appeared to be very similar 

 to th(jse of tlie western Snowbird, as well as to those of the common J. 

 hycmalU. 



Dr. Coues states that he found this bird a not very common winter resi- 

 dent at I\)rt Whipple, where its times of arrival and departure, as well as its 

 general habits, were identical with those of J. orcgofias, with which it very 

 freely associated. From this we niav naturallv infer that in New Mexico 

 and Arizona it appears only as a winter visitant, and that in summer it goes 

 elsewhere to breed. Its summer resorts, as well as our knowledge of its 

 breeding-habits, nest, and eggs, remain to be determined, or are only imper- 

 fectly known. It evidently retires to the highlands and to mountain regions 

 to breed, and probably has a much more extended habitat than that of 

 which we now have any kiiowledge. Upon this problem Mr. Ilidgway's 

 observations have already shed some valual)le and suggestive light. He 

 met with this bird only among the pine woods of the Wahsatch Mountains, 

 where, however, it was a very common bird, and where it was also breeding. 

 Its manners and notes were scarcely different from those of J. orfgonvA. It 

 is, however, a shyer bird than the latter, and its song, which is only a simple 

 trill, is rather louder than that of either the hiiemalk or the oirf/oniui. 



Dr. Cones writes me that both " the ( J rav-head and the Oregon Snowbirds 

 are common species about Fort Whipple in winter, arriving about the middle 

 of October, and remaining in nund)ers until early in April, when they thin 

 ott', although some mav usuallv be observed during the month, and even a 

 part of the next. Orrf/omfs far outnumbers caniceps. So far as I could 

 see, their habits are precisely the same as those of the eastern Snowbird. 

 During snow-storms they used to come familiarly about our quarters, and I 

 once captured several of both species, enticing them into a tent in which 

 some barley had been strewn, and having the flap fixed so that it could be 

 pulled down with a string in a moment. They always associated together, 

 and once, on firing into a flock, I picked up a number of each kind, and one 

 Junro hyemalvi. The latter can only be considered a straggler in this region, 

 althougii I secured three specimens one winter." 



This species was very nire in Colorado, according to Mr. Aiken, in the 

 winter of 1871 -72, but became common in March, and a few remained up 

 to the od of May. No females of this species were observed by him.
