466 NORTH AMERICAN FAUNA. [no. 27. 



was common June 19 to 28, being noted almost daily, usually in scat- 

 tering woods of poplar and Banksian pines. 



Nests containing eggs were found by Alfred E. Preble on June 20 

 and 27, the eggs, five in number, being fresh in each instance. The 

 first nest was embedded in the moss at the foot of a clump of dead 

 willows near the edge of a dense spruce forest. It was rather slightly 

 built of dead grass with a lining of the same material, and was pro- 

 tected from above by the overhanging bases of the willows, and by 

 the strips of bark which had fallen from them, so that the nest could 

 be seen only from the side. The second nest was more bulky, was 

 composed outwardly of shreds of bark, coarse grass, and Equisetum 

 stems, and was lined with fine grass. It was placed on the ground 

 beneath a small fallen tree, in a clearing which had been swept by fire 

 a year or two previously. The set collected on June 20 (No. 29619, 

 National Museum) may be described as follows: Ground color pure 

 white, sparingly marked with small spots of raw umber, cinnamon, 

 dark ecru-drab, and lavender, the latter color in most cases underlying 

 the other markings. The spots are thickest at the larger end, where 

 they usually form a broad and irregular band. These eggs measure 

 as follows: 17.5 by 13; 17 by 12.8; 16.6 by 12.4; 16.8 by 12.2; 17.2 by 

 12.4. The other set (No. 29618) , taken June 27, is noticeably different 

 in coloration. In three of the eggs the ground color is pure white, 

 heavily spotted, principally about the larger end, where the spots form 

 a distinct ring, with burnt umber, fawn, lavender, and a few specks 

 of black. In the two remaining eggs the ground color is creamy- 

 white, almost completely obscured by very fine specks of brown, and 

 with larger spots of fawn scattered here and there, and spots of burnt 

 umber, fawn, and lavender, together with a few black specks, covering 

 the larger ends. The eggs in this set average slightly shorter and 

 relatively broader than the others, and measure : 15.6 by 12.6 ; 16.2 

 by 12.8 ; 16.2 by 12.2 ; 16.2 by 12.2 ; 16.4 by 12.8. 



Later in the same season the Tennessee warbler was noted at Fort 

 Resolution, July 9, and I took newly fledged young at Fort Rae, July 

 19 and 27. 



In the spring of 1903 we first noted this species at Cascade Rapid 

 on the morning of May 28, finding it abundant and in full song. We 

 next observed it on the lower Athabaska, where it was common, May 

 30 to June 1. It was common on Rocher River, June 6 to 8 ; at the 

 mouth of Peace River, June 9; at Smith Landing and on Smith 

 Portage, June 1 1 to 13 ; and on Slave River between Fort Smith and 

 Fort Resolution, June 15 to 19. At Fort Resolution it was frequently 

 noted during the latter part of June. 



During the forenoon of June 25, an extremely windy day, we 

 observed a remarkable movement of these warblers. They came 

 from the northward, flying over the point of land on which the fort
