exceptionally) at Cambridge and near Springfield t respectively ; 

 several birds, such as the Bald Eagles and Pileated Woodpeckers, 

 have been so far driven from the State as probably to breed here 

 no longer. In regard to the dates already given, there is apparently 

 evidence that our summer residents may have formerly arrived and 

 laid their eggs somewhat earlier than they do now. 



In July, singing is much less constant than in May or June, de- 

 creasing as summer advances, though occasionally heard in autumn 

 (chiefly from the Finches), and rarely in winter (from the Song and 

 Tree Sparrows). 



VIII. AUGUST. 



During this month, many birds leave their summer haunts, and 

 even become gregarious, and some journey to the southward, as 

 is occasionally observable even in the latter part of July. The 

 Goldfinches, however, sometimes lay their first set of eggs after 

 July, during which month many other birds have their second or 

 even third broods. 



IX. SEPTEMBER. 



During this month, the (smaller) Hawks are often abundant, many 

 migrating, but the migrations of our birds of prey cannot be easily 

 determined as regards the dates. The Baltimore Orioles, Bobo- 

 links, Chimney Swifts, Cuckoos, Flycatchers (except the Pewees and 

 occasionally the Great Crested Flycatchers), Henslow's Buntings, 

 House Wrens, Hummingbirds, Indigo Birds, Rose-breasted Gros- 

 beaks, Swallows (of whom some go in August), Tanagers, Vireos, 

 Warblers (or most of them : see October), Wilson's Thrushes, and 

 Yellow-winged Sparrows finally disappear, many occurring as mi- 

 shores of a few remote ponds in Wor- Winter Wren, Mourning Warbler,
