126 SPRING BIRD MIGRATION, ANTIGONISH, 1914 LEWIS. 



Other parts of Nova Scotia in other years, April 24 appears to 

 be a normal date of arrival for this bird. The individual seen 

 on that date at Antigonish was clearly observed in the bare 

 branches of an apple tree. On the days immediately following 

 I sought faithfully for this Warbler, or I always tried to obtain 

 dates of second observations as close to arrival dates as possible, 

 and, as day after day went by without my seeing anythng more 

 of the species, I hunted for it the more persistently. Yet t 

 was not observed again until fifteen days after the first indi- 

 vidual was seen; then, on May 9, it suddenly became common. 



59. Seiurus aurocapillus. — Oven-bird. — First seen. May 18 

 (1); next seen. May 20; common. May 20; very common. 



60. Seiurus noveboracensis. — Water-Thrush. — First seen. May 

 17 (2); next seen. May 19; common. May 20; common transient; 

 not common summer resident. In most of western Nova Scotia 

 this bird appears to be uncommon or rare. About Antigonish 

 I found it. by compar.son, rather more common as a summer 

 resident and very much more common as a transient visitor in 

 spring. In summer it is confined to deep, swampy woods, 

 where there is stagnant water, but in the migration its cheerful 

 song sounds not only in such places, but along every brook and 

 river and body of fresh water, large or small. Apparently 

 Antigonish is on the main highway followed by individuals of 

 this species which breed in Cape Breton and Newfoundland, 

 and, perhaps, eastern Labrador. The comparative rarity of the 

 species in western Nova Scotia would seem to indicate that 

 these eastern migrants enter the province by way of the Isthmus 

 of Chignecto.

 May 30 (I); next seen. May 31; not common. More common

 First seen, May 21 (4); next seen. May 22; common. May 22;
