record is furnished by a specimen in Mr. Sennett's collection, labeled 

 September 21, 1889. 



171. Cyanospiza cyanea. Indigo Bunting. 



Of regular occurrence as a summer resident, although not common. 

 May 9 was the date of its appearance in 1894 (Bacon). Curiously 

 enough, we did not meet with this species on the Peninsula in 1900, 

 although the locality seems an ideal one for its presence. 



172. Spiza americana. Black- throated Bunting. 



This species is admitted to the list on the strength of the following 

 note, contributed by Mr. Bacon : " On several occasions I have seen 

 and heard a bird that I have identified as this species, which is there- 

 fore to be counted a rare summer resident. June 9, 1895, I saw one 

 singing and heard two others. ' ' 



173. Piranga erythromelas. Scarlet Tanager. 



Tolerably common as a summer resident, frequenting the wooded 

 portions of the Peninsula and mainland. It arrived May 8 in 1900, 

 and reached the height of its abundance May 20. In the fall the last 

 (and only one) was seen September 26. These dates are probably a 

 fair average index of the arrival and departure of the species. Several 

 nests have been found by Mr. A. M. Howes in the woodland along 

 the bluff facing the lake, west of the city. In every case they were 

 built on the horizontal branches of hemlock trees in deep woods, and 

 May 30 usually found the sets complete. 



174. Progne subis. Purple Martin. 



"A summer resident, nesting commonly in the city limits in boxes 

 provided for the purpose. Observed dates of first appearance are 

 April 15, 1892, and April 13, 1893." (Bacon.) It is seldom seen 

 on the Peninsula. A female was taken there May 29, 1900, and in 

 the fall migration two birds were observed August 24. 



175. Petrochelidon lunifrons. Cliff Swallow. 



In suitable situations on the mainland this species is a rather common 

 summer resident, but on the Peninsula it occurs only during the mi- 

 grations. It was quite numerous in the vicinity of Big Pond on April 

 24 and 25, 1900, in company with other swallows. In 1902 Mr. 

 Simpson noted it first on April 26. 



176. Hirundo erythrogaster. Barn Swallow. 



Like the last a common summer resident on the mainland, but found 

 on the Peninsula only during the spring and fall migrations. Mr.
