20 THE CONDOR Vol. X 



something to eat with more or less regularity, he was far too energetic to let that 

 be all, and taking as much interest in the object of the trip as I did myself, he 

 really did as much collecting as I, and was of great assistance in preparing speci- 

 mens. The following is a list of the birds observed: 



1. Colymbus nigricollis calif ornicus. Eared Grebe. Common at Grand Ivake, 

 May 10-12. 



2. Hydrochelidon nigra surinamensis. Black Tern. Seen June 1, flying 

 about over the meadows along Bear River, five miles above Steamboat Springs. A 

 dozen or fifteen were seen. 



3. Merganser americanus. American Merganser. A duck we supposed to be 

 of this species was seen on Bear River, near Steamboat Springs, June 6 and 8. 



4. Fulica americana. American Coot. One or two seen on Grand I^ake, 

 May 10. 



5. Phalaropus lobatus. Northern Phalarope. June first I killed one on a 

 little branch of Oak Creek,, about 8 miles above Steamboat Springs. It seems 

 rather a late date for the bird to be there as it does not breed in Colorado. 



6. Ardea candidissima. Snowy Heron. One was seen on a bar in Grand 

 River, near Kremmling, May 17. 



7. Porzana Carolina. Sora. One was caught in a trap set for muskrats, in a 

 slough at I^ay. At that date, June 17, it was no doubt breeding there. 



8. Actitis macularia. Spotted Sandpiper. Seen practically everywhere we 

 went that there were any streams or water. A nest and eggs were found at lyily, 

 Routt County, June 30. 



9. Oxyechus vociferus. Killdeer. The first one was seen May 12, on Still- 

 water Creek, between Sulphur Springs and Grand lyake. After that seen pretty 

 much everj^ where we went. 



10. Dendragapus obscurus. Dusky Grouse. Seen at Sulphur Springs, and 

 near our camp at Sheephorn Pass, in Grand County. 



11. Lagopus leucurus altipetens. Southern White-tailed Ptarmigan. Only 

 one was seen during the trip, while we were at Boreas Pass; in fact this was the 

 only time we were in a locality inhabited by them. 



12. Centrocerus urophasianus. Sage Grouse. Seen in the vicinity of Sulphur 

 Springs during my stay there. June 14 we saw a hen with three chicks about two 

 weeks old, about 8 miles west of Craig. The next day, at L,ay, we saw another 

 hen and three young, the latter being much larger than those seen the previous 

 day. July 5, I saw well grown young near Meeker. The bird is quite numerous 

 in some localities. 



13. Zenaidura carolinensis. Mourning Dove. First seen May 12, at Still- 

 water Creek, between Grand I^ake and Sulphur Springs. After that seen every- 

 where. Nests and eggs found at Craig, June 12-13, and one nest and eggs near 

 Douglas Spring, June 27. 



14. Cathartes aura. Turkey Buzzard. Seen near Craig, at Sand Creek, and 

 Snake River, Routt County; and near Meeker. 



15. Circus hudsonius. Marsh Hawk. Not as many seen as one would ex- 

 pect, and these were mostly at various places in Routt County. The only other 

 locality was Mud Springs, Garfield County, on the White River Plateau. 



16. Buteo borealis calurus. Western Red-tailed Hawk. Seen at Sulphur 

 Springs March 29. After that they were seen more or less frequently everywhere 

 we went. 



17. Aquila chrysaetos. Golden Eagle. Seen at Yampa, Oak Creek, below 

 Steamboat Springs, and on Snake River, all in Routt County; and one at White
