13. Colaptes cafer collaris. Red-shafted Flicker. — Often heard; 

 several present but rather sh\ . 



14. Aeronautes melanoleucus. White-throated S\\ift. — Onl\ two 

 seen, flying together ovei- ^allev, Ma>' 24. 



15. Stellula caliope. Caliope Humahngbird. — Q^iite numerous in 

 tiie valley; conspicuous and excited ; on two occasions males went straight 

 up some sixtj feet, there remained suspended at the same place for half a 

 minute, dropped down and rose again to repeat the performance ; also 

 seen to dart up from prominent station into the air, catch an insect and 

 return to same perch like a flycatcher. 



16. Sayornis nigricans semiatra. Black Phcebe. — Only once met 

 with, near Pohono J3ridge. 



17. Contopus richardsoni richardsoni. Western Wood Pewee. — 

 One of the common sounds heard in the valley was the note of this bird, 

 perched high up in trees ; while feeding they were often low down near 

 the ground. A nest in a California black oak was nearly fifty feet above 

 the ground. 



18. Empidonax difficilis. Western Flycatcher. — Among several 

 Empidonaces seen, this is the onl}' one identified with certainty, while 

 among the others were probably Wright's Flycatcher. 



19. Empidonax wrighti. Wright's Flycatcher. — Identification open 

 to doubt. 



20. Cyanocitta stelleri frontalis. Blue-fronted Jay. — Pretty com- 

 mon, but rather quiet and retiring. 



21. Scolecophagus cyanocephalus. Brewer Blackbird. — A small 

 troop was always on the meadow near the village. 



22. Coccothraustes vespertinus montanus. Western Evening Gros- 

 beak. — One pair near hotel. 



23. Carpodacus purpureas californicus. California Purple Finch. 



24. Carpodacus cassini. Cassin Purple Finch. 

 2^. Carpodacus mexicanus frontalis. House Finch. 



This being my first acquaintance with the western Carpodaci the iden- 

 tification of the different species gave me considerable trouble and my 

 notes on this genus are somewhat clouded, but it appeared to me that all 

 three species were present. On the 24th a female House Finch was busily 

 engaged building a nest in a maple near the hotel, while the mate indulged 

 in song flights. 



26. Astragalinus tristis salicamans. Willow Goldfinch. — Only once 

 seen, May 21. 



27. Astragalinus psaltria psaltria. Arkansas Goldfinch. — Four 

 together on the 21st. 



28. Spinus pinus. Pine Siskin. — Several pairs in immediate vicinity 

 of the hotel doing much singing and often hopping on the ground in the 

 street, so tame that they could ahnost be touched with the foot. 



29. Zonotrichia leucophrys leucophrys. White-ckowned Sparrow. 

 — Single individuals in half a dozen places, often in song, which does 

 not at all difler from that heard in the Mississippi Valley.
