SPRING BIRD MIGNATION, MIGRATION, 1914 LEWIS. I 23 



25. Euphagus carolinus. — Rusty Blackbird. — First seen. 

 April 8 (5); next seen, April 9; common, April II; tolerably 

 common transient rare in summer. 



26. Quiscalus quiscula aeneus. — Bronzed Grackle. — First seen, 

 April 7 (I); next seen, April 8; common, April 12; common. 



27. Carpodacus purpureas purpureus. — Purple F'.nch. — 

 First seen. May (1); next seen. May 10; common. May 11; 

 common. Although individuals of th^s species not infrequently 

 pass the winter in Nova Scotia, my notes lead me to believe 

 that migrants usuaUy do not arrive until late April or early May. 



28. Astragalinus tristis tristis. — Goldfinch. — First seen, May 

 26 (1); next seen, May 27; common. May 28; very common. 

 Individuals of this species also are known to winter in Nova 

 Scotia, but it would appear from my notes that the migrants 

 generally arrive in the latter half of May. 



29. Pooecetes gramineus gramineus. — Vesper Sparrow. — First 

 seen April 28 (3); next seen, April 29; common, April 28; tolerably 

 common. 



30. Passerculus sandwichensis savanna. — Savannah Sparrow. — 

 First seen, April 26 (2); next seen, April 27; common, April 30; 

 common. 



31. Passer her bulus nelsoni subvirgatus.— Acadian Sharp-tail- 

 ed Sparrow. — First seen, June, 3 (I); next seen, June 4; un- 

 common. 



32. Zonotrichia alhicollis. — White-throated Sparrow. — First 

 seen, May 8 (I); next seen, May 9; common, May 9; abundant 

 summer resident; breeds. It will be observed that this speces 

 arrived on the night of May 7-8, and that the Fox Sparrow de- 

 parted on the same night. At Halifax, N. S., in 1918, the Fox 

 Sparrow departed and the White-throated Sparrow arrived on 

 the night of April 28-29. In both of these instances the Fox 

 Sparrow had been a very common transient. The feeding habits 

 of these two species appear to be essentially similar, as they both 

 feed largely on the ground among bushes, and it is possible that 

 this fact, in combination with the comparative scarcity of food 

 in early spring, when much of the ground is still snow-covered, 

 may have aided in causing these species to be thus complement- 

 ary in Nova Scotia at that season. 



33. Spizella passerina passerma.— Chipping Sparrow. — First 

 seen. May 9 (2); next seen. May 10; common. May 15; very 

 common summer resident; breeds.
