Tin: notes relative to distribution of Colorado birds gathered for the Biological Survey during the field seasons of 19054)6-07, in connection with work on the life zones of that State, contain important geographical or vertical extensions of the known ranges of at least 34 species and subspecies.Moreover, two other species have been found for the first time within the State.At the request of Dr. C. Hart Merriam, chief of the Biological Survey, these are now placed on record.Mergus serrator.RED-BREASTED MERGANSER.--A_mounted specimen was seen in the Estes drug store at La Veta in May, 1907.Mr. E. W. Scott, the owner, stated that it had been shot on a reservoir near the town.Egretta candidissima.SNowY HERoN.--Althoughoccasionally reported from both sides of the mountains, the following two specimens seem worth recording.While in the White River region in 1906 I learned on reliable authority that a Snowy Heron had been killed near White River P.O. the previous summer, being afterward mounted at Meeker.A mounted specimen seen in the Estes drug store at La Veta in May, 1907, is said to have been killed in that vicinity.The altitude of La Veta, 7000 feet, is exceptionally tfigh for this species.Helodromas solitarius cinnamomeus.WESTERN SOLITARY SANDPIPER.--Apair seen on Deer Creek, 10 miles north of Kremmling, Middle Park, July 13, 1905, may have been on their breeding grounds.Bartramia longicauda.BARTRAMIAN SANDPIPER.--Thisplover is possibly of more general occurrence in western Colorado than has been supposed.Migrating birds were heard at our camp on Bear River, south of Lay, Routt County, the night of August 6, 1905, and others were heard in migration at Meeker on several occasions between August 9 and 14, usually after nightfall.Two were also seen on a meadow near Meeker, August 12.A lone Bartramian Sandpiper seen August 9, 1907, on a timothy stubble at the head of Smith Fork, in the West Elk Mountains, apparently had become separated from a flock of migrating birds, as it was bewildered, and remarkably tame.The altitude was unusual for Bartramia, being over 7000 feet, while the record is the most southwestern for the State.Lophortyx californicus.CALIFORNIA PARTRIDGE.--FromGrand Junction, where first introduced, this quail has spread up the Gunnison Valley at least to Hotchkiss, where it was found in abundance in August, 1907.
