adjoining elm, and decayed cherry tree." Whether they continued 

 to nest there does not seem to be known; at least it is not recorded. 

 But William Brewster (1906) found them breeding there in 1867 

 and has published several more nesting records for that general re- 

 gion up to 1877 or 1878. He says : "Since then no one, so far as 1 

 am aware, has noted the Olive-sided Flycatcher in the Mount Auburn 

 region, even during migration." 



In 1900 and 1901 we located two pairs of olive-sided flycatchers 

 breeding in the vicinity of Triangle Pond in Plymouth, Mass. This 

 is rather high, rolling, sandy country, covered with a scattering, open 

 forest of pitch pine {Pimis rigida) and a rather dense undergrowth 

 of scrub oaks and other underbrush, with several ponds in the hol- 

 lows. These birds continued to breed here until 1905, but since then, 

 though I have hunted the region repeatedly (and such noisy birds 

 could hardly be overlooked), I have never seen them there. Outram 

 Bangs found two sets of eggs in the adjoining town of Wareham, 

 where the forest growth is similar, in 1892 and 1894, but, though I 

 have also hunted this country quite thoroughly, I have found no 

 evidence that olive-sided flycatchers have nested there since that 

 time. Apparently this species no longer breeds in eastern Massa- 

 chusetts. 



Dr. Dickey writes to me: "In the Canadian red-spruce {Picea 

 rubens) belts of West Virginia and western Maryland, where a few 

 pairs of olive-sided flycatchers annually summer and breed, I have 

 observed them among those singular bog formations locally known 

 as 'cranberry marshes,' or 'The Glades,' at altitudes above 2,700 feet." 

 They also inhabit "fringes of evergreens" along some of the rivers, 

 and "certain taller groves of spruces in Garrett County, Maryland." 

 He also found a few pairs spending the summer and breeding, for 

 several seasons, "in the white pine and hemlock forests along the 

 upper reaches of the Allegheny River in Pennsylvania." 



S. F. Rathbun says in his notes: "When I came to Seattle more 

 than 40 years ago, the shoreline of Lake Washington presented an 

 almost unbroken line of forest. At that time the species was abun- 

 dant, and every mile or so of the woods along the lake appeared to 

 have its pair of these birds. This flycatcher is more or less common 

 in the Puget Sound region and is well distributed. I have found it 

 from as high as 4,000 feet (and no doubt it ranges higher) to the 

 very border of the Pacific Ocean ; where one walks along the beach, 

 the calls of this bird often mingle with the long, slow wash of the 

 waves on the sands." 



Major Bendire (1895) says: "In Colorado the Olive-sided Fly- 

 catcher reaches an altitude of 9,000 or 10,000 feet in summer. In 

 the San Pedro Martir Mountains, in Lower California, Mr. A. W.
