also obtained a male and a female at Elliot Pond near Chocorua 

 on November 9, 1900, from a flock of about 10, and states that 

 the bird seemed to be unknown to the residents there. 



31. Anas obscura Gmel. Black Duck. 



A common spring and fall migrant and in the southern part 

 of the state a rare summer resident, though breeding not un- 

 commonly in the more northern areas. According to Mr. Wil- 

 liam Brewster (: 02) it still breeds plentifully at Lake Umbagog. 

 In the country about Intervale, although a few birds are to be 

 found here and there throughout the summer, it is not until the 

 last of August that they appear in any numbers. Near Monad- 

 nock, Mr. G. H. Thayer has found it a rare summer resident. 

 During September and October flocks of from six to thirty are 

 found about the rivers and large ponds, and on the wind-swept 

 lakes until early November. 



Dates : March to December. 



32. Anas obscura rubripes Brewster. Red-legged 

 Black Duck. 



A spring (?) and late fall migrant. This newly described 

 duck is stated by Mr. Brewster ( : 02) to be common in migra- 

 tion at Dake Umbagog from the second week of October until 

 the waters are closed by ice, the earliest date of its capture 

 there in fall being September 28, 1899. Mr. C. F. Goodhue 

 has in his mounted collection a specimen of this duck taken 

 late in the fall, years ago, at Webster. It doubtless occurs also 

 in spring, but I know of no records.
