Vol. XXIJ Bailey, Birds of the Upper Pecos. 355 



Stellula calliope. Calliope HuiMmingbird. — Two specimens were se- 

 cured during the summer, one at 11,000 feet on August 8, and one three 

 miles south of Pecos on August 25. 



Tyrannus vociferans. Cassin Kingbird. — Reports of vociferans were 

 brought us by McClure Surber from Glorieta on Julj 8, and from 8000 

 feet on August 19. 



Myiarchus cinerascens. Ash-throated Flycatcher. — In the juniper 

 belt near Glorieta Myiarchus was found about July 8. 



Sayornis saya. Say Phcebe. — On August 14 Mr. Bailey found a Say 

 Phoebe on an open ridge at 12,000 feet, where Afyadestes, Anthus, and 

 Otocoris had been found previously. At Glorieta one had been seen 

 around an adobe about July 8. 



Nuttallornis borealis. Olive-sided Flycatcher. — Nuttallomis was 

 found in the Canadian and Hudsonian zones from Willow Creek at 7800 

 feet to the foot of Pecos Baldy at 11,600 feet, its familiar call often coming 

 from the tip of a picea spire. 



Contopus richardsonii. Western Wood Pewee. — Richardsonii was 

 seen in the Transition zone from 7000 to 8000 feet. 



Empidonax difficilis. Western Flycatcher. — Common from 8000 

 to 11,000 feet, evidently breeding at 11,000 feet on July 15. Mr. Henshaw 

 saw young accompanied by the parents July 19, and on Jack Creek, at 

 11,000 feet, Mr. Bailey found a nest containing four young on August 5. 



Otocoris alpestris leucolaema. Desert Horned Lark. — At least half 

 a dozen Horned Larks, among them full grown young, were found with 

 a band of Pipits on a broad open slope at 12,000 feet. They were dis- 

 covered on July 28, on our first visit to timberline, and found in the same 

 place a number of times afterwards. Two specimens were secured which 

 Mr. Oberholser identified as leucolcema. 



Pica pica hudsonia. Black-billed Magpie.— Four magpies and 

 three or four ravens were seen August 6 sitting on a corral on the open 

 mesa at 10,400 feet. The carcass of a cow was evidently the attraction 

 and the ravens were trying to drive off the magpies when discovered. 

 On being disturbed the birds all flew off down into the timber. 



Cyanocitta stelleri diademata. Long-crested Jay. — Cyanocitta was 

 found from the lower edge of the Transition zone yellow pines through 

 the firs and spruces of the Canadian zone, but at 11,000 feet it was largely 

 replaced by Perisoreus. At 7000 feet, near Glorieta, about July 8, a 

 family of six were seen going around together. At Sooo feet, on July 16, 

 an old jay brought its brood into the bushes on the edge of camp, 

 running out into the grass a few yards from our tent to pick strawberries 

 for them. On August 21, at the same altitude, we found another pair of 

 jays going about with their young. 



Aphelocoma woodhousei. Woodhouse Jay. — On the Pecos ivood- 

 housei was found as high as 7000 feet, for although the cold slopes of the 

 caiion walls are pineclad at this altitude, the warm slopes are covered 

 with Upper Sonoran junipers and nut pines.
