BIRDS OF THE CAMBRIDGE REGION. 



99 



It is probable that Leach's Petrel also appears in the Back Bay Basin on 

 rare occasions, for Dr. Charles W. Townsend tells me that in September or 

 October, 1898 or 1899, he saw what he took to be a bird of this species flying 

 about near Harvard Bridge. 



No other instances of occurrence relating to the Cambridge Region are at 

 present known to me, but a Petrel, supposed to have been a Leach's, was seen 

 by my friend, Mr. Daniel C. French, skimming over the Sudbury River at Fair- 

 haven Bay, Concord, some time in the autumn of 1870 (if I remember rightly), 

 and Mr. Charles J. Paine, Jr., has given me the skin of a bird that was shot by 

 his brother, Mr. John B. Paine, on October 14, 1904, at Wayland, where it was 

 flying over the marshes that border the Sudbury River just below the old stone 

 bridge. There is also a published record by Mr. A. P. Morse ^ of a Leach's 

 Petrel which was taken at Farm Pond, Framingham. 



It is an interesting fact that Wilson's Petrel', although much more numer- 

 ously represented in summer off our coast than is the species just considered, has 

 never been found at any inland locality in Massachusetts. 



15. Phalacrocorax dilophus (Swains.). 

 Double-crested Cormorant. 



Accidental visitor in autumn. 



On September 16, 1889, Mr. William P. Hadley and Mr. E. B. Winship 

 saw a flock of about a dozen Cormorants, all apparently alike, flying over Great 

 Meadow, which, at that time, was covered with water. The birds finally alighted 

 well out from shore, when Mr. Hadley and his companion, after procuring a 

 boat, approached them within long gun-range and shot two of them. One of 

 these specimens was skinned by Mr. J. R. Mann and has since come into my 

 possession. It is a young female Double-crested Coi^morant in its first winter 

 plumage. 



I know of no other instance of the appearance of the species in the Cam- 

 bridge Region, but I have seen it once at Concord, Massachusetts, and it occurs 

 regularly and rather commonly, especially in autumn, at Ipswich, Nahant and 

 various other places along our seacoast.
