Frank Bolles appears not to have observed the bird here in sum- 

 mer, however, nor did I find it during a day and night spent 

 near the summit of Chocorua in late August. On Moat Moun- 

 tain, an adjacent ridge, I have nevertheless observed a single 

 bird on July 17, 1898, in a damp thicket of spruces at hardly 

 more than 2,700 feet, and others in early September, 1902, in 

 the stunted growth at 3,000 feet. Dr. Walter Faxon tells me 

 that at Mount Moosilauke. he has found these birds arriving on 

 their breeding grounds between the 25th and 3oth of May, and 

 that a nest was observed there by Mr. William Brewster and 

 himself, which on June 22d, contained the full complement of 

 three fresh eggs. On the Presidential and Carter Mountains, 

 where I have been familiar with the bird, an occasional out- 

 lying pair may be found as low as perhaps 2,600 feet in some 

 cold brook bed, but they are commonest from about 3,300 feet 

 up to the limit of small tree growth, at about 4,800 feet. They 

 are silent much of the day, and are effectually concealed in the 

 almost impenetrable thickets of scrub growth. In the early 

 dawn and after sunset, they are active, however, and from all 

 sides may be heard their clear, wild call-note, or less often the 

 far-away, high-pitched notes of their song, strangely impressive 

 in the mountain solitudes. The song period is practically over 

 by the middle of July, though I have heard an occasional song 

 in the early morning as late as September i5th, in Carter Notch, 

 where at this date the birds are still on their breeding grounds. 

 They are then only to be heard, however, in the very early 

 morning or just at dusk. On September 15, 1900, while camp- 

 ing in the notch by the lakes (3,360 feet), I arose early and by 

 4 o'clock A. M., the first dim light of dawn was faintly to be 

 discerned over the eastern wall of the notch. At just 4 : 37 A. 

 M., as the pale light of the half moon was giving place to the 

 first rays of day, a single Bicknell's Thrush was heard far over- 

 head, on the big ledge which faces the east and forms the other 

 side of the notch. Soon others were heard above, but as the 

 sun, some while later, struck the upper ledges, only the birds 

 still in the shadow below continued to call. It was most inter- 

 esting to note the manner in which the birds successively became
