I4O Beckham on Birds observed at Pueblo, Colorado. [April 



Pueblo is one hundred and twenty miles south of Denver, at 

 the junction of the Fontaine qui Bouille and the Arkansas River, 

 forty miles west of the point where the latter emerges from the 

 mountains. The surrounding country is a dreary waste of cac- 

 tus, sage-brush, and soap-weed, but along the river and the 

 creek, the vegetation is comparatively luxuriant. Naturally nine- 

 tenths of the birds are to be found in these more favored localities. 

 Owing to other engagements but little time could be given to col- 

 lecting, and the list is therefore necessarily incomplete. 



The writer is indebted to Mr. Ridgway for material assistance 

 in preparing these brief notes. 



1. Hylocichla ustulata swainsoni {Cab.). First observed on May 13 

 and by the 20th they had become very common. 



2. Merula migratoria propinqua Ridgiv. Abundant. 



3. Oreoscoptes montanus {Towns.). Not common. Preferring, with 

 obviously bad taste, the cactus and sage-brush of the plains to the luxu- 

 riant vegetation along the water-courses. Its song is very soft and low, 

 as if it were disinclined to 'waste its sweetness on the desert air.' 



4. Mimus polyglottus (/,.). Rather common on the outskirts of the 

 town. The same versatile mimic here as everywhere else. 



5. Galeoscoptes carolinensis {L-). Not common and rather shy. 



6. Harporhynchus rufus {L.). An abundant bird along the streams. 



7. Cinclus mexicanus S~v. One seen in a canon in the Greenhorn 

 (Sierra Mojada) Mountains, thirty miles southwest of Pueblo. 



8. Sialia sialis (/,.,). A female, the only one recognized, was shot on 

 April 25. 



9. Sialia mexicana Sw. Rather common up to the first of May. Fre- 

 quently seen out on the prairie, as well as along the streams. 



10. Sialia arctica. Sw. More abundant than the preceding. Breeding. 



11. Myiadestes townsendi {And.). First observed April 22. and they 

 afterwards became rather common up to June 1. Much on the ground, 

 and generally somewhat shy. Heard no note at all from them at this time, 

 but during the last week in September they were very abundant at Mani- 

 tou, forty-five miles northwest of Pueblo, in Williams Canon and the 

 Garden of the Gods, where their delightfully sweet songs were often the 

 only sounds to be heard in those rocky solitudes. 



12. Parus montanus Garni. A small party of four or five were ob- 

 served April 6 in Greenhorn Canon, thirty miles southwest of Pueblo. 



13. Thryomanes bewicki leucogaster Bd. The only one seen, a male, 

 was shot out of an old stunted cottonwood, containing several abandoned 

 Magpie nests, about which the bird dodged for fully fifteen minutes before 

 giving me a chance to shoot. This record, I believe, considerably extends 

 the known range of the form. 



14. Troglodytes aedon V. Common on the outskirts of town, but 

 none were seen in the town itself.
