370 HISTRIONICUS HISTRIONICUS 



to nest at Ovecho and Marcova. In the interior it probably nests as far north as 65°. Von Bunge and 

 von Toll (1887) noted it on the Lena below Yakutsk and Buturlin (jide Dresser, 1908-09) found it in 

 the Werchojansk Mountains. 



Specimens and eggs have been taken at Chaivo and Chipesani, Saghalin (Lonnberg, 1908; Hesse, 

 1915) and on the Kuriles the species is said by Stejneger (1898) to breed abundantly. Steller {fide 

 Saghalin Pallas, 1831) found it a common nesting bird in Kamchatka, but von Ditmar (1900) 

 Kuriles says it is only a migrant there. Specimens have been taken throughout May in south- 



Kamchatka eastern Kamchatka (W. S. Brooks, 1915), and in summer on the Commander Islands, 

 where, however, the species does not seem to nest (Stejneger, 1885; Hartert, 1920). 



The Harlequin is very common on the Aleutians in summer, but few if any nest (Unalaska?) (Dall, 

 1874; L. M. Turner, 1886; Nelson, 1887; R. C. McGregor, 1906; A. H. Clark, 1910; Bent, 1912). On 

 Aleutians the mainland it is a rare bird along the coast from the mouth of the Yukon to Kotzebue 

 Alaska Sound (Nelson, 1887) though a few nest along the tributaries of the Yukon and along 



the upper Yukon itself (Dall and Bannister, 1869; Bishop, 1900; Blackwelder, 1919). In Bering Sea it 

 has been seen on St. Matthew's in July (G. D. Hanna, 1917) and on the Pribilovs it is common (Coues, 

 1875; W. Palmer, 1899), probably not breeding. In southern and southeastern Alaska it is quite 

 abundant in summer, even breeding to some extent. Osgood (1904) found it common about the base 

 of the Alaska peninsula, and Gianini (1917) met with some numbers in summer at Stepovak Bay. 

 Bretherton (1896) says the species nests on Kadiak Island, and it certainly does so on Hinchinbrook 

 Inlet and on the Montague Islands (U.S. Biological Survey). F. M. Chapman (1904) has recorded it 

 from Bird Island late in July, and Loring (1902) from Knik River in June. In southeastern Alaska 

 it is common at Sitka and nests (?) in the vicinity (J. Grinnell, 1898; Willett, 1914; A. M. Bailey, MS.). 



In Yukon Territory and northern British Columbia, C. Sheldon (1911) and Swarth (1922) have re- 

 Yukon ported it quite common on the upper Stikine and in the Pelly Mountains, where it has 

 British been found nesting near Dawson, at White Horse Rapids and on the Pelly Lakes, as 

 Columbia we ll as near Telegraph Creek on the Stikine (U.S. Biological Survey). It is rare on the 

 Queen Charlotte Islands, but has been found nesting on the Bear River, Vancouver, and is said to do 

 so along the coast of British Columbia also (Fannin, 1891 ; Kermode, 1904). In the interior of British 

 Columbia, A. Brooks (1917) took nests in the Chilliwack region, but found it a scarce summer resi- 



... dent in the Cariboo district. Eastward, in the Rockies, nests have been taken on the 



Alberta 



Alberta border at Hector (J. and J. M. Macoun, 1909), near Banff (Spreadborough, 



fide J. and J. M. Macoun, 1909), and on the Athabasca and Smoky Rivers (U.S. Biological Survey) 

 as well as in Jasper Park (Taverner, U.S. Biological Survey). 



There is no very good evidence that the Harlequin nests anywhere in the MacKenzie and Atha- 

 basca basins. R. M. Anderson (1917) has recorded specimens taken at Barter Island on the Arctic 

 MacKenzie coas t °f Alaska in June, and others from Herschel Island and MacKenzie Bay. Indeed, 

 Raine (1892) says he has eggs sent him by missionaries from the mouth of the Mac- 

 Kenzie (!) and C. A. Reed (1904) lists a clutch supposedly taken on the Peel River. 

 This is all the evidence available at present, though the species has been seen or taken about La Pierre 

 House, Great Bear Lake, Fort Simpson, Fort Rae, Lake Hardisty, Fort Resolution, Fort Halkett (fide 

 Baud, Brewer and Ridgway, 1884; Frank Russell, 1898; Preble, 1908) and farther south at Chipewyan 

 and Lake Claire (Harper, MS.) as well as along various tributaries of the Athabasca (Spreadbor- 

 ough, fide J. and J. M. Macoun, 1909). A specimen has also been recorded from York Factory 

 (Blakiston, 1863). 



In the western States of the Union the Harlequin is very common in summer on some of the islands 

 of Puget Sound (W. L. Dawson and Bowles, 1909; Edson, 1908) but these appear to be non-breeding 

 Western birds. Some are said to breed in the Cascades (W. L. Dawson and Bowles, 1909) and 

 United in the Olympic Mountains downy young have been seen (U.S. Biological Survey). 



States d q Elliot (1898) has recorded a nest from Wenatchee on the upper Columbia. Pos-
