128 BULLETIN : MUSEUM OF COMPARATIVE ZOOLOGY. 



Three specimens : 



a. 9 March 19, 1904. 



b. 9 March 19, 1904. 



c. 9 March 19, 1904. 



Chimney Swifts were tirst noticed on March 16 and 17, when a number 

 were seen flying about near the house. More were observed on the 19th. 

 They were abundant in the late afternoon, and at about sunset they filed grad- 

 ually into the vertical well-shaft to roost. On the 19th one of the Indians went 

 down in the well after dark with a lantern and obtained several specimens. 

 The birds were not seen about again until the 23d, and I have no record of them 

 after that date. The note impressed me as rather less loud and harsh than that 

 of Chaetura pelagica.
