July, 1908 ANNOTATED LIST OF THE BIRDS OF MESA COUNTY, COLORADO 



153 



parture of species at Grand Junction, which have been used in this list in practic- 

 ally their entirety. 



Miss Myra Eggleston, Ouray, Colorado, formerly of Grand Junction: An 

 annotated list of 47 species observed by her in that vicinity, and complete notes on 

 19 species, that have been copied verbatim in the absence of any other informa- 

 tion on those particular species. 



Mr. Floyd Smalley, Collbran: Notes on 10 species observed by him in Plateau 

 Valley, which had not been encountered by the writer. 



Dr. M. V. Watson, Plateau City: Migration notes on 6 species of ducks 

 qbserved by him in Plateau Valley. 



Mr. E. R. Warren, Colorado Springs: An annotated list of 22 species observed 

 in the vicinity of Grand Junction. 



Mr. P. McCaffrey, DeBeque: Migration and nesting notes on the ducks 

 at DeBeque. 



State Historical and Natural History Society, Denver: Notes on 3 species 

 collected by Messrs. Will C. Ferrill and H. G. Smith at Grand Junction. 



Without the above information much of the relative completeness of this list 

 would be lacking, as nearly all of it covered information not contained in the 

 writer's notes. 



Notwithstanding the information collected from various parts of the County 

 there yet remains a large number of species whose established range undoubtedly 

 includes Mesa County, and whose absence from this list can only be accounted for 

 by the small amount of information available regarding Mesa County Ornithology. 



Beside the many species which wnthout doubt occur regularly in the County 

 there are also a number of western species whose extreme eastern limit may extend 

 to western Colorado, and if this is the case, the valley of the Grand River forms a 

 natural highway into Mesa County from the west which is probably the route trav- 

 eled by these western species. 



Prof. Cooke in his Birds of Col- 

 orado says, "The whole of north- 

 western Colorado remains unex- 

 plored. What a field for the Orn- 

 ithologist! As large as the whole 

 of New England outside of Maine, 

 and containing the whole valley of 

 the Grand River and its tributaries, 

 it will reward the zealous seeker 

 with many Pacific forms not now 

 known to Colorado. No other part 

 of the State will probably show so 

 large a return as the region around 

 Grand Junction." It is unfortu- 

 nate that this list does not bear out 

 Prof. Cooke's last statement more map of Colorado showing position of mesa county 

 fully, as only a few rare western 



forms are included in it (and nearly all of these were furnished by Prof. 

 Cooke), but the fact that it does not bear him out in no way detracts from 

 the force of his statement, as most of the observations from that section are of a 

 very general nature and practically no close study or collecting has been done in 

 that locality, and it is perfectly safe to predict that careful study of this section 

 will be productive of many rare and unique discoveries.
