Lapland Long-Spur. Plectrophanes Lapponicus. 



" Very rare, and found only in severe winters " (Turnbull). My 

 observations have determined that single specimens of this bird 

 are not unusually found in the flocks of the preceding species. 



Savannah Sparrow. Passerculus Savanna. 

 Transitory. Abundant only in spring and autumn. 



Grass-Finch. Pocecetes gramineus. 



Abundant, resident, and the most " domestic " of our birds. In 

 the fields in which these birds are hatched they appear to remain, 

 throughout their lives. They are as abundant in January as in 

 June. Dr. Turnbull considered them migratory, and speaks of their 

 numbers as " being augmented in summer by flocks arriving early 

 in April." 



Yellow- winged Sparrow. Ammodromus passerinus. 



"Common, arriving late in April/ and departing in October" 

 (Turnbull). 



Henslow's Bunting. Ammodromus Henslowi. 



Never common. Varies greatly in numbers from year to year. 



Sharp-tailed Finch. Ammodromus caudacutus. 



"Frequent on the salt marshes along the coast" (Turnbull). 

 Not uncommon on the inland tide-water meadows of the Delaware 

 River. 



White-crowned Sparrow. Zonotrichia leucophrys. 



Never abundant, but still not rare. They appear often as early 

 as September, and remain until the spring following is well ad- 

 vanced. 



White-throated Sparrow. Zonotrichia albicollis. 



Common from September to May, often inclusive of the latter 

 month. 



Tree- Sparrow. Spizella monticola. 



Abundant from October to April, both inclusive. A statement 

 made by the writer in 1868 ("Geology of New Jersey"), that this 

 species was " resident," was a careless blunder. 



Field-Sparrow. Spizella pusilla. 



" Common. Comes early in April and leaves in October " (Turn- 

 bull). If the weather is pleasant, they remain until December.
