AUGUST AND SEPTEMBER BIRD-LIFE NEAR PHILADELPHIA 



By Witmer Stone 



August and September are the great months of southward migration, 

 corresponding to April and May of the spring movement. It is true that 

 none of our summer resident species leave us entirely until the first week 

 in September, but migrants are passing during the greater part of both 

 months. The berry-bearing trees and bushes are great rendezvous for birds 

 at this season, and many species can be seen and studied if the observer 

 takes his stand in the vicinity of a group of wild-cherries or clump of 

 pokeberries. The molt of many birds may be noted at this time, and 

 we can easily distinguish the ' fork-tailed ' Robins, which are just beginning 

 to lose their feathers, and the 'wedge-tails' in which the new plumage is 

 nearly grown. 



Much that goes on during these months is missed by the observer 

 because of the heat and other drawbacks of midsummer, which render 

 field work a serious matter. Then, too, the birds are silent, retiring and 

 listless, in marked contrast to their activity during the spring migration or 

 the first crisp days of October. 



By September i, nearly all birds, old and young, have assumed their 

 winter plumage, and the dull blended colors and lack of many character- 

 istic markings of the nuptial season render identification more difficult. 



Our first winter visitants, the White -throated Sparrows, reach us by 

 September 20, and sometimes the Junco is to be seen before October i.
