gust 15, Seiitembei- 5-0, 1910. Ou the last date a bright plumaged 

 bird came to the opening in my tent and remained in an enquiring 

 attitude until I made a movement in the direction of the camera, 

 when he skurried away with a loud chatter. 



Wilsania pusllla pusilla. — Wilson's Warbler. 



The first seen was on August 12. four the next day. and a few 

 each day until the 30th, when it became common and remained 

 so to the end. None seen except in 1910. While the numbers re- 

 mained tew the mo;-t of the records were made at the swamp, 

 but when the birds became ctjmmon they spilled over among the 

 cedars, and ranged to Uie limit of vegetation on the point. They 

 were not at all wary, and permitted close approach. 



Wilsonia canadensis. — ^Canadian Warbler. 



It was present on September 1, 1905, and in 1910 the first was 

 noted on August 11, the next on -the 13th, and beginning with the 

 15th there were several recorded each day during our stay. It 

 seemed to be pretty closely confined to the underbrush in the 

 vicinity of the swamp, but occasionally it wandered down the point 

 amont: the cedars. On September 1, 1910, it was recorded as tol- 

 erably common. On that day it wa^ found at the limit of vegetation 

 on the point. 

 Setophaga ruticilla. — Redstart. 



Present and in sutficient numbers to warrant being called de- 

 cidedly common on all visits to the island. It was evidently breed- 

 ing in considerable numbers in all of the woodlands visited. In 

 1910 it was singing during the entire time of our stay. 



J t mm t dill ciiioJinciiNix. — ('iitl)ir(l. 



Found on all visits to the island in small numbers. Pretty 

 closely confined to the region of the swamp, but occasionally found 

 among the cedars and in the shrubery along the west beach. The 

 scarcity of thi< usually common species was the most notable thing 

 about it. 



To-roxtftiiiii nifniii. — Brown Thrasher. 



Present and common on all visits. About the first bird seen 

 when one lands near the limit of vegetation on the point. It was 

 the most numerous in the bushes along the west beach where 

 the wild grapes were abundant, and many individuals were seen 

 eating the grapes. There seemed to be a noticeable increase in 

 numbers when the first migratory movement occurred, about Au- 

 gust 12, but no birds were seen to cross to Middle Island, and 

 none even made the start in daylight.
