GEOLOGICAL SURREY OF THE TERRITORIES. 



At Ogdeii I found an old nest of this bird, sliowiug that they had re- 

 cently lived here. They are still quite abundant in Ogden Canon, and 

 at many other places in the Wahsatch Eange near Ogden. Port i^euf 

 Caiion is the first place where we found magpies. Here they were very 

 common, as they were at Pocotello, where I obtained a good specimen, 

 No. 146 (61780.) I also saw a few at Fort Hall and on Snake Eiver, 

 about forty miles above the fort. We saw none after this until on our 

 return, when we met them on Snake Eiver, east of the Tetons. After 

 this they were common all the way down till we arrived within about 

 fifty miles of Ogden.

This splendid bird is the Eocky Mountain representative of Steller's 

 jay, {G. Stelleri,) which it differs from, principally, in having a white 

 spot over the eye, the crest being longer and fuller, the streaks on the 

 forehead being white instead of greenish blue, and the whole head being 

 darker. 



The long-crested jay is not an uncommon bird in the Wahsatch Mount- 

 ains. They are quite numerous, however, in tbe Teton Eange, where I 

 obtained two specimens. 



At Shoshone Lake, on the 7th of September, I saw a flock of about 

 twenty gray jays, [Perisoreiis canadensis.) Among them was a beautiful 

 long-crested jay, which I succeeded in shooting. It — No. 256 (62243) — 

 was in full plumage, and is one of the finest specimens I ever saw. When 

 first disturbed thej^ fly about in an angry, scolding manner, offering you 

 a fine shot ; but you must not delay long, for they soon lose their curi- 

 osity and retire into the forest, keeping themselves hid among the pines. 

 I have often seen them early in the morning imitating the voice of the 

 hawk-owl {Surnia ulula) as they flew about from tree to tree.

Hah. — Central line of Eocky Mountains. 



Woodhouse's jay is quite common at the foot of the Wahsatch Eange, 

 where I obtained two specimens, the only ones that were seen by any of 

 our party during the summer. They are the Eocky Mountain represent- 

 ative of the California jay, {G. californica,) which they greatly resemble, 

 the principal difference being in the under parts, which are much darker, 

 and in the bill, which is longer and more slender. They are both western 

 representatives of the Florida jay, {G. floridana,) which they c-iosely
