BIRDS COLLECTED AND OBSERVED 
Aechmophorus occidentals (Lawrence), Western Grebe 
On the morning of departure one was near the dock in Vancouver 
harbour. Not seen farther north, though it was known to be at this date 
at Comox, Vancouver island, where it wintered. 
Colymbus holboelli (Reinhardt). Holboell’s Grebe 
Observed only on the outgoing voyage, at Prince Rupert, Cordova, 
Unalaska, Alaska, Atka island, and Yetorup island in the Kurils. In all 
cases single individuals were seen, except at Unalaska and Yetorup island. 
Not observed in the western Aleutians, Komandorskis, or on Kamchatka, 
but at Hitokappu anchorage (Yetorup island), on the morning of May 7, 
four were on the bay and were heard grinding out their weird plaint. 
<? Cordova, Alaska. March 15, 1924. Winter plumage. 
Colymbus auritus (Linnaeus). Horned Grebe 
Like the previous species, only stragglers were in evidence. Several 
were seen at Trout harbour, B.C., one each at Yakutat bay and Cordova, 
and about a dozen at Unalaska. 
c? Trout harbour near Bellabella, B.C. March 3, 1924. Full winter plumage. 
Gavia immer (Brunnich). Loon 
The identification of loons was a most unsatisfactory matter. Birds 
probably of this species were seen at Trout harbour, Prince Rupert, 
Wrangell, Taku, Juneau, Unalaska, and Atka. Most of these were in the 
immature grey or winter plumage. In a large congregation of sea-birds 
following the herring near Prince Rupert, about twenty loons were seen. 
Some of these certainly were stellata. Just what proportion of all birds seen 
were adamsi it is impossible to say. Strangely, pacifica did not appear 
anywhere to be recognized on the inside passage, though it winters com- 
monly at Comox, V.I. No loons were seen in the western Aleutians or on 
the Asiatic side, in spring. 
Gavia adamsi (Gray). Yellow-billed Loon 
cf Uyak bay, Kodiak island, Alaska. March 21, 1924 
In juvenile plumage and very like similar plumage of the Common Loon , but differing as follows: 
bill scarcely longer than that of immer, but very deep in comparison with length. Culmen arched 
as much as in many specimens of that species, but a stronger angle at the gonys. Though the bill 
is as short as immer, the feet are decidedly bigger. These characters — deep bill, angular gonys, 
and large feet seem to be good distinctions for juvenile adamsi. 
Gavia arctica (Linnaeus). Black-throated Loon 
On May 19 a loon was observed among the shipping in Hakodate 
harbour. Its whitish head and hindneck were very plain as it swam about 
near the ship, and designated it as this species. 
On July 15, at Petropavlovsk, two were seen doubtfully, and again on 
the 31st, during a foggy morning, two, thought to be the same species, 
went by, calling “ Ark-ark-ark’ ’ rapidly rasped and rather guttural. The 
writer has heard the Pacific Loon give these same notes while on the wing. 
Gavia pacifica (Lawrence). Pacific Loon 
Not definitely identified. This species is gregarious in winter; prob- 
ably, therefore, the flocks were secreted in out-of-the-way harbours such 
as Comox, Vancouver island, where on February 20 a flock of about one 
hundred was noted.
