402 Cooke, The Birds of Colorado. Loc£ 



Notes on several species of birds seen on a journey from the mouth 

 of the Purgatory to Raton Pass. 



Abert, J. W. Notes of a military reconnoissance from Fort Leaven- 

 worth in Missouri to San Diego, in California, including part of the Arkan- 

 sas, Del Norte and Gila Rivers, by Lieut. Col. W. H. Emory. Appendix 

 No. 6. Notes of Lieut. J. W. Abert. 30th Cong., First Session, Exec. 

 Doc. No. 41, 1848, 386-546. 



Contains a list of birds found in the vicinity of Bent's Fort, and addi- 

 tional notes on those seen between Bent's Fort and Raton Pass over 

 nearly the same road as that travelled the previous year. Had these 

 two reports by Lieut. Abert been available when the original 'Birds of 

 Colorado' was written, there would have been several changes in the 

 statement of who first recorded each species in Colorado. Abert's two 

 reports together contain the first records for the State of thirteen species.
