1SS7- Beckham oh Birds observed at Pueblo. Colorado. 121 



the spring, were published in this journal (Vol. II, 1883, pp. 

 139-144), where are given brief notes on ninety-one species. 



In the fall of 1SS6 I spent a month at the same place, from 

 October 4 to November 4, and all of the thirty-one days but four 

 were spent in the held. The result of this activity is the addition 

 of twenty-two species and subspecies to the avi-fauna, and some 

 interesting notes on birds enumerated in the previous list. 



At the time of my arrival most of the transients and summer 

 residents had left for the South, and a good man)' presumable 

 winter residents had put in their appearance. 



The weather during the whole of my stay was typical of the 

 usual Colorado autumn ; that is, the next thing to perfection — 

 cloudless skies, cool nights, and warm days, with now and then 

 a dust storm, thrown in doubtless for the purpose of stimulating 

 our appreciation of the good things we had been enjoying in the 

 meteorological line, and preventing us from growing tired of 

 them. 



The birds apparently did not like these cold dust storms any 

 better than the unfeathered bipeds, for during their prevalence, 

 it seemed impossible to find one anywhere ; the most favored 

 avian haunts were entirely deserted, and no amount of 'beating 

 about the bush' would bring forth even a chirp. 



I experienced the usual number of disappointments and sur- 

 prises, which about balanced each other ; I did not find some 

 species that I expected to meet with, and found others which 

 were not expected. Belonging to the former class may be men- 

 tioned Zenaidura macroura and Melancrpes erythrocephalus, 

 both of which were excessively abundant there in the spring of 

 1SS3. The latter species, however, is notably inconstant in this 

 respect ; its movements being doubtless regulated by the food 

 supply. 



Additions to the List given in 'The Auk,'' Vol. II, /8S?, pp. 139-jjj. 



92. Gallinago delicata. But one seen. Flushed from a marsh, Octo- 

 ber 29. 



93. Circus hudsdnius. Two of these Hawks were seen on October 11. 

 They approached within a very short distance of me and were easily rec- 

 ognized. 



94. Dryobates villosus harrisi. None were seen in 1SS3. but in 1886 I 

 found it to be the most abundant Woodpecker about Pueblo, and very 

 tame and unsuspicious ; in marked contrast with my experience of D. vil-
