SPRING BIRD MIGRATION, ANTIGONISH, 1914 LEWIS. 121 



the colony, so easily accessible, had been raided by human en- 

 emies in the interval between my two visits. 



2. Anas rubripes. — Black Duck. — First seen, March 28 (2); 

 next seen, April 10; apparently uncommon. 



3. Branta canadenis canadensis. — Canada Goose. — First seen, 

 March 19 (10); next seen, March 29 common, March 19; 

 common; last seen, May 7; a transient only. Apparently 

 these birds pause in their migration for some time at this point, 

 until conditions farther north are favorable for a resumption 

 of their movement to their breeding grounds. During April 

 the great shallow areas in Antigonish Harbor form the feeding- 

 ground of large flocks of Canada Geese, containing several 

 thousand individuals. 



4. Botaurus lentiginosus. — American Bittern. — First seen. May 

 10 (1); next seen, May 13; common. May 21; common.

 April 27 (1); next seen, April 30; not common.

 20 (2); next seen, April 22; not common. When passing through 

 Antigonish County in 1917, I saw a single bird of this species 

 on the upper South River on April 10.

8. Aegialitis semipalmata. — Semipalmated Plover. — First 

 seen. May 15 (5); next seen, May 23; not common. Probably 

 not an accurate record of first arrival. The only place where 

 1 observed this species was Mahoney's Beach. 



9. Aegialitis meloda. — Piping Plover. — First seen, May 23 

 2); next seen, June 13; rare. Perhaps not an accurate record 



of first arrival. The only place where I observed this species 

 was Mahoney's Beach, at the mouth of Antigonish Harbor. 

 When 1 visited the Beach on May 15, none were seen, but 2 

 were there at the time of my next visit, on May 23. The great- 

 est number of individuals seen in one day was 4, seen June 13.
