THE CONDOR 
VOL. XI 
Before turning our attention to the local work two lists must be mentioned as 
among the important contributions to our state ornithology. 
The first was a paper written by Mr. F. M. Drew “On the Vertical Range of 
Birds in Colorado”, which was publisht in the Auk in 1885. This paper, which 
contained notes on 277 species of which four were new to the State, was by far the 
most important contribution to our knowledge of bird distribution up to that time, 
and even up to the present date it remains a standard reference work. 
The other paper, entitled the “Birds of Colorado”, was written by Mr. Chas. 
F. Morrison and publisht in the “Ornithologist and Oologist” in 1888-89-90. I 
can not do better than to quote Prof. Cooke. Speaking of this list he says, “It is 
the most extensive list of Colorado birds publisht up to this time. Begins with 
No. 1 of the A. O. U. Check-List and closes with No. 570 enumerating 233 
species. The list was never completed, owing to the destruction by fire of much 
of the material. In addition to records of birds already publisht, the author had 
the use of a large amount of unpublisht notes sent him by local collectors. The 
list if completed at that time would have shown 326 species, but as the records of 
some 14 species recorded here have since been ascertained to be incorrect it would 
reduce the real number to 312 or 35 more than Mr. Drew’s list publisht three 
years previous.” 
In the earlier part of our discussion we noted the routes followed by the vari- 
ous exploring expeditions that touched this State and got a fair idea of the scope 
covered by their reports; but for obvious reasons their observations were of a tran- 
sient nature, and as a rule contained very little regarding the local status of any 
given species. Let us now turn our attention to the men who, while not covering 
such a large scope of country, confined their efforts to some restricted area and 
worked out the ornithological problem to greater or less completeness. 
As I have said before the first real local lists that were publisht were con- 
tained in J. A. Allen’s paper publisht in I 872 . This paper contained three lists 
of importance, one list of 81 species observed in Colorado during July and August, 
a list of 54 species observed in South Park, Park County, in July, and a list of 36 
species observed during the same month on Mt. Lincoln, Park County. 
The Henshaw report publisht in 1874 contains two local lists. One of these 
is a list of 82 species observed at Denver, and the other is a list of 104 species 
observed at Fort Garland, Costilla County. 
In this same year the very complete notes of Mr. T. M. Trippe on the birds of 
Idaho Springs and vicinity (Gilpin and Clear Creek Counties) were publisht in 
“Birds of the Northwest”, but as they are scattered thru the body of the book 
their segregation into a local list is difficult. 
In 1879 W. E. D. Scott publisht a list of 60 species observed at Twin Lakes, 
Lake County, and this, so far as I know, is the only publisht record referring 
specifically to Lake County. 
In 1881 Mr. F. M. Drew publisht the results of several years’ active work 
in southwestern Colorado as “Field Notes on the Birds of San Juan County, Col- 
orado.” This list contains 104 species, including six species new to the State, and 
gives much valuable information regarding breeding habits, migration and occur- 
rence. 
In 1882 and 1884 Mr. D. D. Stone publisht two short lists of birds observed 
above 11,000 feet in the vicinity of Hancock, Gunnison County. The first list 
treats of 16 and the second of 18 species, and while these lists are very small they 
are of unusual interest owing to the altitude at which they were taken. 
In 1883 Allen and Brewster publisht an annotated list of 134 species observed
