This late song is sometimes given quite as well as in the 

 spi-iiig. An Oriole which had lived on ni)" place all summer, 

 and whicli had such a peculiai' song that it was easily recog- 

 nized, as if the bird said, "■ Take me zvilh yon r Xo yon don/, 

 Ao yon don'/. See! '' gave this song in detail on .Vugust 21, 

 ]{)()(), when in the eharacteristicly bright plumage of autumn, 

 O.'her bii'ds, pro])ably always the young, give either mur- 

 inm-ing imitations of the spring song of the adult, as is done 

 by the Song, Swamp, White-throated, and other sparrows, or 

 give fragments of the true song. On August 30, 1901, a 

 young male Rasc-breasted Grosbeak alighted on the cupola 

 of my barn and uttered a portion of the regular song, in 

 which was curiously mingled the metalic-like '■ c/ick^^ which 

 this species uses as an alarm note. 



It ap[)ears to me, that just after the autumnal moult some 

 birds a|)pear to possess enough unexpended energy to affect 

 the reproductive organs, causing a slight inclination to breed. 

 This inclination is exhibited, not only in the song, but also in 

 some cases, in attempts to mate. I saw some Barn Swallow^H 

 last August, mostly young, acting nearly like mated l:»ii-ds ii> 

 the spring. 



MiGRATiox AXJ) BREEDrx'a Kax(ie. The Pine AYar- 

 blers breed throughout Eastern Xorth America, west to the 

 Plains, f I'om Florida to Xew Bi'unswick, wherevei- the differ- 

 ent species of pitch or hard pines occur, hence is rarely ever 

 found in the hemlock, spruce and wdiite pine forests of north- 

 ei-n Xew England. 



The northward migration occurs early, the birds arriving 

 in Massachusetts from the first to the last w^eek in April, de- 

 pending upon the weather. 



In autumn most of these Avarl)lers leave Massachusetts 

 during the last two weeks in September, but stragglers stay 

 later, in fact, a few have been known to remain all winter, I 

 have never found them at this season, however, north of the 

 Carolinas.
