Barrow's Golden-Eye loi 
in the common species it extends only over one-third of its breadth. This is a good point 
for identification. 
At the beginning of July the adult male undergoes a fairly complete change to an eclipse 
plumage, although the white feathers in front of the eye are never completely lost. In 
this month the head and neck become a somewhat dirty grey brown, very light in the 
throat ; the flanks, hind neck, and upper mantle, also portion of the lower neck and chest 
are brown with grey edgings ; mantle, scapulars, brown, with light brown or grey edgings or 
tips ; the whole bird now resembles a somewhat dirty-looking female, but its sex can easily 
be recognised by its superior size, small white feathers on the head, and by the wings, which 
always remain the same, which, with the tail and part of the back and tail-coverts, are only 
moulted once in the season. The adult male has scarcely assumed its eclipse dress before 
it again commences to moult into winter plumage, and in the case of all these ducks the 
process of change at this season may be said to be practically continuous. A bird before me, 
shot on October 4th, shows that a great proportion of the winter plumage has already been 
assumed on the cheeks, mantle, scapulars, and back. The hind neck and flanks seem to be 
the last parts to lose the eclipse feathers. By the second week in November the adult 
male has again reassumed his full dress. From the fine series of these birds in my own 
and Mr. E. Lehn Schioler's collections, it is quite clear that Barrow's Golden-Eye follows a 
course of plumage from birth to maturity similar to the Common Golden-Eye. 
Breeding Range. 
Ornithologists such as Hantzsch, Slater, Coburn, myself and others who 
have visited Iceland bear testimony to the commonness of this species in the Myvatn district, 
where it breeds in some numbers. It also breeds in small numbers in the east and west of 
the island near the coast, where there are rivers flowing into lakes. I did not see the species 
in the south, but only one female of the Common Golden-Eye with young. 
Greeitland. — Breeds in the south between 63° 45' and 64° 30' N. (Holboll), apparently 
not further north than Godthaab. It is common about Julianshaab (Dr. Deichmann). 
With reference to its breeding range in Greenland, Mr. E. Lehn Schioler kindly sends 
me the following note : — 
" The main breeding-place for Barrow's Golden-Eye in Greenland is supposed to be in the Godthaab 
district. It has been proved that it occurs, probably breeding in the fjords, along the west coast from 
Nanortalik to Godthaab, and I have secured specimens from Julianshaab. Godthaab was taken to be the 
limit of its distribution to the north, but the Zoological Museum here has a male from Governor Fencker's 
collection shot ist of June 1896, near Holsteinborg, and I have received several specimens from 
Sukkertoppens district, mostly young birds, however. 
** We must not forget that a good many birds cross over from America, so specimens met with 
farther north may not have been reared in Greenland. 
*• Information on the point is to be found in Winge's Grdnlands Fugle, 1898, and with Holboll. 
** My friend Dr. Krabba, who has stayed in Greenland twelve years, mostly in the Godthaab 
district, tells me that there is a certain place up in the Godthaabsfjord where the bird is always to be met 
with in summer ; it is near some waterfalls on inaccessible little islands, and the nest is therefore never 
taken ; this is well in accordance with Holboll's remarks. The name of the little ' Udligger '-place is 
Kornok, the very spot where my Clangula gL am. was killed." 
N. America. — Breeds ''from the Gulf of St. Lawrence, Rocky Mountains, Moun- 
tains of Colorado, and Alaska northwards " (Dresser) ; N. Montana (Coues), Kicking Horse
