WARBLERS 555 



of its occurrence seem to be few. It seems to be transient in 

 the southern counties of our State, and a rare summer resident 

 in the counties of the Canadian fauna. Boardman gives it in 

 his list of the " Birds of the St. Croix Valley " as " very rare." 

 It is reported " common " at Fort Fairfield, Aroostook County, 

 (Batchelder, Bull. Nutt. Orn. Club, Vol. 7, p. 110), and is 

 reported as occurring at Upton by Mr. Wm. Brewster. I find 

 no mention of it in the late Clarence H. Morrell's notes at 

 Pittsfield." 



It seems to somewhat resemble its near relative, Geothlypis 

 trichas brachidactyla (Swain.) in its choice of feeding grounds 

 and in its choice of location for its summer home. It is one 

 of the late arrivals in the State, in fact one of the latest of 

 this family to arrive, reaching the interior at about the time 

 the Blackpolls arrive. Soon after its arrival it may be 

 observed, but a pair in a place, feeding about the dense under- 

 brush on the margin of some lowland woods or second growth 

 swamp, or on some side hill, covered with brush, near a deep 

 wooded ravine, and soon after its arrival it begins its nest 

 building. The migration report for 1902 shows that it was 

 first observed near Waterville on May twenty-fourth and at 

 Avon, Franklin County, on May twenty-fourth, (J. M. O. S. 

 Vol. 6, No. 3, p. 80). I find no records of its nest being found 

 in the State. 



Mr. Fred B. Spaulding, of Lancaster, N. H., has found it 

 breeding near his home. He writes me as follows: — " It was 

 not until June 8, 1901, that I found the nest of the Mourning 

 Warbler. On that date, in company with my old friend. 

 Judge Clark, of Saybrook, Ct., we were searching a hillside, 

 near a small trickling stream, when I discovered a nest, new to 

 us both, containing five fresh eggs. The nest was supported 

 by some leaning raspberry bushes, sixteen inches from the 

 ground. No bird was on the nest when I discovered it, but 

 on our retiring a short distance she returned. At our approach 

 she slipped from the nest and ran off through the vines and
