85. Sayornis phoebe. Phoebe. 



A rather common summer resident, regularly nesting on 

 the Highland (1600 feet). The first song period continues to 

 about July 20, and there is a second period of song in August 

 and September. The latest record of a bird singing quite freely 

 is October 2, 1902, on the Highland. The last birds disappear 

 in the first week of October. We had a nesting many years ago 

 on a beam of our piazza, which was successful in the rearing of 

 the young, but while we had admired the beauty of the moss- 

 decorated nest in its freshness, after a period of family life it 

 was a very undesirable possession. 



Mr. Spaulding, writing me under date of April 3, 1910, 

 says, " Phoebes are singing everywhere. It is the earliest 

 spring record I have." 



86. Nuttallornis borealis. Olive-sided Flycatcher. 



A not uncommon summer resident, found in the valley, 

 along the turnpike, and on the mountain slopes where the forest 

 has been cut into and the trees are somewhat sparse. Its bold, 

 challenging song is heard much in such locations and arrests 

 attention. The song period extends to the middle of August or 

 later. Some individuals are usually noted up to early Septem- 

 ber. The latest records have been September 12 and 18 in 1900, 

 and September 14 in 1909. 



87. Myiochanes virens. Wood Pewee. 



A common summer resident in all woodland and regularl}' 

 heard in the large elms on the streets of Ivancaster. The song 

 continues without much abatement to the end of August, is 

 heard commonly into the early days of September, and some- 

 times does not cease until the middle of that month. One was 

 heard singing on September 17 and 19 in 1909. The latest 

 individuals have been seen on September 23, 26, and October 3 

 in 1905, and on September 22 in 1909,
