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 Chipping Sparrow (SpizeUa arizonae socialis, Coues). 



Abundant everywhere throughout the district. A iiest just about ready for depositing 

 eggs was found on the dav 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.) 



Slate-coloured Junco (Junco hyemalis hyemalis, Linnseus). 



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 

 Julv 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.) 



Lincoln's Sparrow (Jfelospiza lincolnii, Audubon). 



Apparently not common. Male and female were obtained at Hot Springs on July 3rd. 

 Thev 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.) 



Cliff Swallow (Pterochefidon 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 Swallow (Hirundo erythrogaster erythrogaster, Boddasrt). 



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.) 



Xorthern Violet-green Swallow (Tachycineta 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.) 



Bohemian Waxwing (Bombycilla garulla, Linnseus). 



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 Mountain Orange-crowned Warbler (Vermivora celata orestera, Oberholser). 



Only one seen and shot at Pike River on August 2nd, which proved to be a worn male. 

 (Idt. Oberholser.)
