382 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



The northward flight of Golden-crests passes through the Cambridge Region 

 in April, when, for a week or two, the birds, although scattered widely, are often 

 very numerous, and when the prolonged, feeble, somewhat halting songs of the 

 males may be frequently heard during clear, warm weather. 



Golden-crested Kinglets continue to appear in our garden, in autumn, win- 

 ter and early spring, but we see them here much less numerously and fre- 

 quently now than we did thirty or forty years ago.

The Ruby-crowned Kinglet visits us only during migration, the spring 

 flight ordinarily beginning soon after the loth of April and terminating early in 

 May, while the autumnal movement is mainly accomplished during the month of 

 October. Although of perfectly regular occurrence at both seasons, the active, 

 interesting little birds are seldom very numerous, it being unusual to meet with 

 more than three or four in the course of a single day ; on exceptional occasions, 

 however, I have known as many as a dozen or fifteen to be noted. In spring, 

 when the males make themselves conspicuous by their incomparably brilliant, 

 rapidly flowing songs. Ruby-crowns frequent all kinds of places, including upland 

 woods composed of either coniferous or deciduous trees, apple orchards, and 

 shade trees or ornamental shrubbery near houses. Their favorite haunts at 

 this season are swampy thickets — especially of shrubby willows — on the bor- 

 ders of brooks, ponds and meadows. In autumn one is most apt to find them
