45. Contopusborealis (Swains.). {Olive-sided Flycatcher). 

 This species is a rare migrant in Cohuilla Valley and is not com- 

 mon in any part of this section. Only two were seen. Cohuilla 

 Valley April 8th, and near San Gorgonia May 29th. The latter, 

 a $, was laying. 



46. Contopus richardsonii (Swains.). ( Western Wood 

 Pewee). One taken in Cohuilla Valley April 7th, and two at 

 Bear Valley. They are not uncommon in the mountains. 



47. Empidonax difficilis Baird. {Baird^s Flycatcher). 

 Four were taken in Cohuilla Valley and one at San Bernardino. 

 This species frequents the thicker parts of the timber in the river 

 bottoms at Yuma where they are quite abundant. They were re- 

 peatedly shot for E. obscurus and E. hammundi. Only one was 

 taken in Bear Valley. 



48. Empidonax hammondi (Xantus). [Hammond 's Fly- 

 catcher). One was taken April 14th, in Cohuilla Valley. A few 

 were noted at Yuma although they were comparatively rare. A 

 $ was shot June 26th in Bear Valley. She had incubated and 

 would have laid again shortly. 



49. Empidonax obscurus (Swains.). ( Wright's Fly- 

 catcher). This is a very rare bird in the Cohuilla Valley where I 

 have taken but one; that April 8th. Another was taken at Ban- 

 ning, April 2 1st. At Yuma they were also comparatively rare, 

 while none were observed at the other places visited. 



50. Pyrocephalus rubineus mexicanus (Scl.). ( Vermil- 

 lion Fly-catcher). This species was found only at Yuma where 

 they were not nearly so common as I had expected to find them. 

 Young were taken as early as May 6th. 



51. Otocoris alpestris rubea Hensh. [Ruddy Homed 

 Lark). None seen in Cohuilla Valley or at Yuma. They were 

 common on the plain between Banning and San Gorgonio. I have 

 often found them abundant around Riverside (especially in winter), 

 where they breed in the vineyards, orchards, etc. They are very 

 seldom seen about San Bernardino where the ground is probably 

 too damp to suit them. 



A small flock was seen along the marshy bosder of the lake in 

 Bear Valley June 8th. 



52. Cyanocitta stelleri frontalis (Ridgw.). {Blue- 

 fronted Jay). Abundant in the lower pine regions, but rare in 

 Bear Valley. Probably because it is above the oak region where 

 their food is found.
