1926] Swarth: Birds cmd Mammals from the Atlin Begion 133 



E. M. Anderson (1915, p. 15) has described the nesting of a pair of 

 barn swallows on a passenger coach that traverses the two-mile portage 

 at Taku. The birds still rear their broods in the same place. For 

 their convenience a box is affixed near the roof of the coach within 

 (the sides of the car are open) , and year after year the box is occupied. 

 The coach travels back and forth across the portage several times a 

 week, filled with people, throughout the nesting period. 



Iridoprocne bicolor (Vieillot). Tree Swallow 

 Arrived at Atlin on June' 3. Found by us nesting only about 

 human habitations, but during the third week in July there were so 

 many young tree swallows gathered upon the largest of the three 

 islands nearest to Atlin that it seemed as though they must have been 

 reared elsewhere than in the town. 



Tachycineta thalassina lepida Mearns 

 Northern Violet-green Swallow 

 Abundant at Skagway, May 21, at Carcross, May 22, and at Atlin, 

 when we reached there on May 28. Last seen near Atlin on Septem- 

 ber 1. There are no rocky ledges near Atlin, such as the violet-green 

 swallow occupies elsewhere in the north, and as with all the other 

 swallows found breeding in the region, they were nesting about human 

 habitations, occupied or deserted, and nowhere else. 



Riparia riparia (Linnaeus). Bank Swallow 

 A flock of migrating bank swallows appeared near Atlin on June 10, 

 and a single bird was seen on July 12. The species was not otherwise 

 observed. 



Bombycilla garrula pallidiceps Reichenow. Bohemian Waxwing 

 A single bird seen at Carcross, May 24. At Atlin, the third week 

 in May, waxwings were fairly common and in pairs. On June 3 the 

 beginning of a nest was found, on June 4 one that was ready for 

 lining, and on June 11 the first set of eggs. These and several other 

 nests were on the mainland, not far from the. lake shore, and in rather 

 open groves of jack pine. Nests were mostly near the ground, the 

 highest being some thirty feet up. They were all in the terminal forks 

 of downward drooping branches, six to ten feet from the trunk.
