nished five records, when one has been located favorably within 

 hearing. The time of first song has ranged from 3.40 to 4.17, but 

 on the three other occasions was earHest heard at 4.05, 4.10 and 

 4.11 respectively. The average time is 4-05 o'clock. 



36. The Bobolink's {Polichonyx oryziwrus) time of first sing- 

 ing is based on nine records, ranging from 3.59 twice, 4.01 and 4.03 

 to 4.21 (twice) and 4.22, the average time being 4-^0 o'clock. On 

 June 11, 1904, it was precisely 4.10 when one first poured forth on 

 the wing his song of ecstasy. 



37. The Yellow-bellied Sapsucker {Sphyrapicus varius 

 varius) has been heard to call and drum on three occasions, the 

 first sounds coming at 3.51, 4.10 and 4.30 respectively. The 

 drumming is done upon telephone posts at the roadside. The calls 

 usually come when the bird is at work upon birches or apple-trees. 

 The average time of making its presence known has been 4-iO 

 o'clock. 



38. Chimney Swift {Chcetura pelagica). As it passes in rapid 

 flight through the air, the Swift's voice has been recorded on ten 

 occasions, ranging in time from 3.58 and 4.00 to 4.24, and averaging 

 4-10 as the time of its appearance on the wing from its night's 

 rest in the chimney. Thus the Swift appears only two or three 

 minutes before sunrise at the earliest and usually delays until a 

 few minutes after. 



39. The Black-throated Green Warbler {Dendroica virens) 

 furnishes three records when one has been located within hearing. 

 Usually the voices of the two or three birds in near woodland are 

 not heard until one has gone within the woods. The time of first 

 song heard on these three occasions has been 3.56, 4.17 and 4.26, 

 which give an average time of 4-13 o'clock. 



40. Northern Pileated Woodpecker {Phlceotomus pileatus 

 abieticola). There are eight records, when a bird has been heard 

 loudly rapping in the distance with slow and measured blows or 

 has called lustily and long, sometimes answered by another. The 

 times of first hearings range from 3.46 and 3.55 to 4.39 and 4.48 

 and average 4-16 o'clock. Both the calls and the rappings are so 

 loud that they cannot easily be overlooked even if the bird or birds 

 be a half-mile distant either in the valley or on the mountain side. 



41. Cedar Waxwings {Bombycilla cedrorum) have made known 

 their presence by their soft sibilant calls on seven occasions, the
