BIRDS OF COLORADO.

Pagosa Springs. In addition to the species communicated to 
Mr. Ridgway and published by him in 1873, the following are 
given: chen hyperborea^ himantopus mexicanus^ macrorhampus 
scolopaceus^ limosa fedoa^ selasphorus rufus^ spurns psaltria 
arizoncB^ pipilo aberti^ piranga rubra cooperi^ dendroica macu- 
losa^ dejidroica rara^ dendroica striata^ dendroica townsendi^ seiu- 
rus 7ioveboracensis notabilis^ sitta canadensis. 
1877. Ridgway. MaxweW s Colorado Museum. Field 
and Forest^ II. 1876-7, pp. 795 and 208. This is the finest col- 
lection ever made of Colorado birds. It has been claimed that 
every bird in this collection was actually taken in Colorado. 
There seems good and sufficient reasons for believing that some 
of the skins bought by Mrs. Maxwell were really taken outside 
the State. They were all mounted by Mrs. Maxwell and largely 
collected by her. Most of them were taken in the vicinity of 
Boulder, but many were sent to her by friends in other parts of 
the State. Unfortunately nearly all of the data accompanying 
these specimens have been lost and there is now no means of 
ascertaining when or where they were captured. 
Besides the species already given from this collection in 
Ridgway’s List there are the following: stercorarius parasiiicus., 
rissa tridactyla., larus Philadelphia^ xema sabinii.^ phalacrocorax 
dilophus^ mergus serrator.^ clangula islandica., oide^nia americana., 
anser albifrons gambeli., olor columbianus^ tantalus loculator., 
nycticorax violaceus., charadrius sqicatarola^ asio accipitrinus.^ 
nyctala acadica.^ megascops asio maxwellics., megascops flam- 
meola., coccyzus america^tus occideiitalis.^ leucosticte tephrocotis 
littoralis^ calcarius lapponicus.^ vireo solitarius cassinii. Two 
of these, rissa tridactyla.^ and nycticorax violaceus^ still remain 
the first and only records for Colorado. 
This completes the record of all work done in Colorado by 
the government surveying parties and by the individual workers 
that did so much for the ornithology of the state from 1869 to 
1876. The state list at this time numbered 279 species or two 
more than those included ten years later by Mr. Drew in his 
list of Colorado birds. The Maxwell collection is the last large 
addition to the Colorado list. The 81 species that have since 
been added are nearly all rare or accidental visitants and have 
been added a few at a time by a large number of different 
workers.
