Briack-rHroatep Loon (Gavia arctica, Linnzeus). 
Over a dozen seen throughout the summer on Atlin and the smaller lakes. We found it 
more plentiful than Gavia immer. A pair were found breeding at Camp Lake, Wilson Creek, 
on June 15th. I am inclined to think that some of the birds observed at a distance may have 
been the yellow-billed loon (Gavia adamsii, Gray). However, since none were shot, it is 
impossible to list it with certainty. 
Herring Gui (Larus argentatus, Pontopidian). 
While en route to Atlin on June 4th a number of birds were seen feeding on small lakes 
at Log Cabin, Lake Bennett. We found several pairs nesting on a small rocky island at 
Atlin Lake. Fresh eggs were taken on July 8th. Seven adult birds were shot in order to 
ascertain the species with certainty. The eggs, two or three in number, measure 2 x 2.75, of 
an olive-brownish colour, spotted and blotched with various shades of brown. The eggs are 
indistinguishable from Larus glauscens. The nests were all very crude, being composed of 
little or no grass at all. Two eggs were laid in a slight depression in the bare ground. The 
nest is by no means as elaborate as the glaucous-winged gull, which breeds commonly on the 
Pacific Coast. 
Carirornia Gut (Larus californicus, Lawrence). 
An adult female was taken at Warm Bay, Atlin Lake. Two others were seen at the 
same locality three days later. (Idt. Oberholser.) 
Snorr-Bittep Guu (Larus brachyrhynchus, Rich.). 
Three adults were collected at Warm Bay, Atlin Lake, on July 11th, and an immature 
on July 15th at Hot Springs. An adult and young of the year were taken at Pike River on 
August 8th. It is quite evident that the birds breed in the vicinity, as several adult birds 
were seen during the month of July. (Idt. Oberholser.) 
Bonaparte’s Gutu (Larus philadelphia, Ord.). 
A single specimen was shot at Camp Lake, Wilson Creek, on June 10th. On July 3rd 
two adults were collected on a small lake near Hot Springs ; also two downy young were taken 
on the lake-shore. I should judge from the size of the young that fresh eggs could be taken 
about June Ist. Two young with first plumage were shot at Pike River on August 6th. On 
approaching the nest it was amusing to watch the parent birds fly a short distance and alight 
on a tree-top and utter cries of warning for the young to conceal themselves in the grasses or 
swim away to safety ; usually they fled to the opposite side of the lake, returning only when 
assured of being well out of the danger zone. This species was seldom seen on Atlin Lake. 
It preferred the small inland lakes, with grassy shores. Only one nest was found at the edge 
of the lake. It was situated in a small willow-bush, about 5 feet from the ground, composed 
of sticks and lined with grasses. It was not found breeding in colonies, as only one or two 
pairs were nesting on several of the small lakes visited close to Hot Springs. By no means 
a common breeder in the district we traversed. 
Arcric Tern (Sterna paradiswa, Brunnich). 
Common nearly everywhere throughout the district. Birds were taken at Wilson Creek 
from June 9th to July Ist. Alsoa number at Hot Springs and Pike River in July and August. 
They breed at the mouth of O'Donnel River. Young were hatched early in July. ‘Twenty-one 
specimens were collected, varying in measurements. (Idt. Oberholser.) 
Mereanser (Mergus americanus, Cassin). 
A female with seven downy young were found feeding close to the shore at Pike River on 
July 27th. All the young were taken ; the female escaped badly wounded. No others were 
seen. 
Mattarp (Anas platyrhynchos, Linneus). 
A single bird was flushed on Summit Lake, Wilson Creek, on June 25th. Female shot 
at Pike River on July 30th. A young male collected at a swamp near Anderson Bay, Atlin 
Lake, on August 5th. A pair were found with young on a small lake on the Indian reserve 
at Atlin. Three adults collected at Atlin on August 12th. Breeds commonly at the north 
en? of Atlin Lake.
