40 RIDGWAY ORNITHOLOGICAL CLUB. 



This species is not uncommon in the Cohuilla Valley, and at Yuma 

 I found them quite common. On the nth of May, a young Indian 

 brought about five dozen of them into Yuma, he had snared them 

 alive, and I got a selected dozen of them for one dollar. Does not 

 occur at San Bernardino or Bear Valley. 



16. Melopelia leucoptera (Linn.). {White-xvinged Dove). 

 Only two seen, these at Yuma May 15th. They were flying 

 rapidly and crossed the Colorado River. Does not occur west of 

 the Colorado Valley. 



17. Pseudogryphus californianus (Shaw). [California 

 Vulture). At Banning, on April 22nd, while engaged in skinning 



birds I heard the croaking of approaching Ravens-, and, looking 

 up I saw two, pestering what I thought was a Golden Eagle. 

 Snatching my rifle, I fired as they passed at a distance of about 150 

 yards with no other effect than to frighten off the Ravens. 



As the other bird resumed its flight I saw to my astonishment, 

 that it was a small California Vulture. I slipped in another car- 

 tridge and fired again, but with no better success than at first. 

 There was no white about the tail nor under the wings, but the 

 front edge of the wing, from the shoulder to the carpus, had a nar- 

 row edging of white. The head was very pale, almost white 

 apparently. The extent of wings was not over seven feet I think. 

 It was most probably a young bird not nearly grown. 



June 7th, while in Bear Valley, I saw another, this was also 

 an immature bird. On June 8th, I saw another passing over; this 

 one was flying very straight and high, presently three more ap- 

 peared in the wake of the first, those, in turn, being followed by a 

 train of Turkey Buzzards (Cat/iartes aura). 



Two more were seen in this locality June 15th. They passed 

 over at an elevation of 800 or 1000 feet. I fired at them with the 

 rifle, but ineffectually. 



iS. Cathartes aura (Linn.). (7\trkey Buzzard). Some 

 seen in Bear Valley, June 8th. Common. 



19. Accipiter cooperi (Bonap.). (Coopers Hawk). Three 

 seen May 17th and 18th, at San Bernardino. 



20. Buteo borealis calurus (Cass.). ( Western Red-tail). 

 Not common anywhere. One seen at Yuma, one at Riverside 

 and several in Bear Valley. 



21. Buteo Swainsoni Bonap. [Swain son's Hawk). It 

 was reported to me that this bird flies over Riverside in small num- 

 bers every evening during April and May, going from the plains
