a clump of willow-brush, situated about a foot above the ground, composed of grass fibre and 
dried grasses interwoven with a little moss, and snugly lined with ptarmigan-feathers. Each 
nest contained five fresh eggs af a bluish-green colour, spotted and blotched with shades of 
reddish brown, averaging 0.56 x 0.75 in size. (Idt. Oberholser.) 
Western Cuippinc Sparrow (Spizella arizonae socialis, Coues). 
Abundant everywhere throughout the district. A nest just about ready for depositing 
eggs was found on the day of our arrival in Atlin on June 6th. Adults were taken at Wilson 
Creek in June. In August it was common at Pike River, where both adults and young of the 
first plumage were obtained. (Idt. Oberholser.) 
Siare-coLoureD Junco (Junco hyemalis hyemalis, Linnzus). 
Very common throughout the summer. A large series of adults and young were secured 
in the different sections of the country visited. Five sets of eggs were taken in June and early 
July at Wilson Creek and Hot Springs. The eggs, four or five in number, vary considerably 
in size, markings, and colour. Four sets were pale greenish and one almost cream colour, 
spotted finely with various shades of brown, averaging in size 0.55 x 0.75. (Idt. Oberholser.) 
Lincotn’s Sparrow (JMJelospiza lincolnii, Audubon). 
Apparently not common. Male and female were obtained at Hot Springs on July 3rd. 
They were shot in a swamp where they were undoubtedly breeding. An adult male was 
collected in Atlin on August 14th, being shot in a marsh, associated with Western Savanna 
sparrows. (Idt. Oberholser.) 
Curr Swattow (Pterochelidon lunifrons lunifrons, Say). 
Abundant summer resident. Large numbers were found building in the town of Atlin. 
Fresh eggs were taken on June 6th. Adults and young were obtained in Atlin on 
August 8th. 
Barn Swatxow (/Hirundo erythrogaster erythrogaster, Boddert). 
Common at Pike River and Atlin. Several were found in barns in Atlin and left 
undisturbed. A pair were nesting in a small flat car which is used for conveying passengers 
over a portage from Taku to Atlin Lake, a distance of about two miles. The birds fly uncon- 
cerned to and fro from the nest while the train is en route. Mr. Sullivan, the engineer of the 
train, informed me that the birds nest in the same spot yearly, where they raise their young 
unmolested under such novel conditions. A set of five fresh eggs were obtained at Atlin on 
June 6th. A nest was found at Pike River on August 2nd with five young. The young 
were ready to fly on August 8th. (Idt. Oberholser.) 
NortTHern VIOLET-GREEN Swattow (Vachycineta thalassina lepida, Mearns). 
An abundant summer resident. Adults and young taken at Atlin on June 24th. During 
August a number of the three species were starting to move southward. They were first 
noticed at Pike River on August 7th. (Idt. Oberholser.) 
Bonemian Waxwine (Bombycilla garulla, Linneus). 
A common resident. Very abundant at Hot Springs and Atlin. Adults were collected 
in July at Hot Springs and Middle Islands. We were successful in obtaining four sets of 
eggs on July 8th on a small island in Lake Atlin. The nests were placed in small spruce- 
trees, situated from 10 to 15 feet from the ground. The structure is rather a bulky affair, 
composed of dry pine and spruce sticks, interwoven with dried grasses, cottonwood down, 
intermingled with a little fur of the varying hare. Two nests contained five eggs, one four, 
and the other two, all of which were strictly fresh. The average measured 0.100 x 0.75, of a 
bluish-grey colour, spotted with black, and streaked finely with faint purplish markings. 
Although the eggs closely resemble the cedar waxwing’s, the nests are quite distinguishable 
from each other, both in size and structure. 
Rocky Mowunrain OranGe-crowNep WarBtER (Vermivora celata orestera, Oberholser). 
Only one seen and shot at Pike River on August 2nd, which proved to be a worn male. 
(Idt. Oberholser.)
