OCT., 1900] BIRDS OF THE YUKON REGION. 61 



accompanied l)^' others, and until we reached Cape Scott, Octol)er .12, 

 a ghmco astern would seldom fail to show two or three followino- the 

 vessel. 



23. Fulmarus glacialis glupischa. Pacilic Fulmar. 



A single dark-colored fulmar, possibly this form, was seen October 

 4, between St. George and Unalaska. 



24. Oceanodroma furcata. Forked-tailed Petrel. 



To this species I refer a few light-colored petrels seen October 3, 

 on Bering Sea north of the Pribilof Islands. 



25. Phalacrocorax pelagicus. Pelagic Cormorant. 



Cormorants were seen October 4 near Unalaska, where this species 

 is reported as common. 



26. Phalacrocorax pelagicus robustus. Violet-green Cormorant. 



We saw a single cormorant at Whale Island September 8; and one — 

 possibl}^ the same bird — was seen by Osgood several times at St. 

 Michael. 



27. Phalacrocorax urile. Red-faced Cormorant. 



This is the only cormorant reported by William Palmer from St. 

 George, where we saw several October 3. 



28. Merganser americanus. American Merganser. 



A pair of mergansers was breeding on a small, rocky island in Lake 

 Tagish, at the entrance to Windy Arm, June 30-July 1. The nest was 

 found by Osgood in a crevice in the cliffs about 15 feet above the 

 water. It was made of down, and contained seven eggs about one 

 week advanced in incubation. Retrieving would have been impossible 

 had we shot the bird, but as I succeeded in watching the female on the 

 nest from a distance of less than 6 feet I feel positive of the species. 



A few other mergansers, usually in pairs, were seen on Lake Tagish 

 July 1, on Lake Marsh July 8, at Fifty-Mile River July 9 and 12 (a 

 flock of a dozen males flying up the river in the evening of the latter 

 date), near Little Salmon River July 20, and about 25 miles above 

 Circle August 12. Near Charlie Creek we found the dried wing of an 

 adult male of this species August 8. 



29. Anas boschas. Mallard. 



On the flats of Chilkat Inlet I saw seven Juno 2. In no part of the 

 Tukon Valley above Circle did we find ducks abundant, except surf 

 scoters, but the mallard undoubtedly occurs at all suitable places 

 throughout the region. It must breed very early, as on June 24, only 

 three weeks after the lakes were open to steamer navigation, I found 

 a female with two young at Caribou Crossing, and on June 28 I shot
