12. Anas rubripes. Black Duck. 



A regular summer resident breeding in small numbers, and 

 a spring and fall migrant. Black Ducks have been seen upon 

 several of the ponds during all the summer months and more 

 numerously in August, September, and early October. Several 

 summer records were obtained in each of the years 1905 to 1908. 

 In 1909, on June 22, on Cherry Pond were seen two mothers 

 with their broods of eight and six ducklings respectively, the 

 young about one-third grown. In 1910, on June 29, a company 

 of eleven birds, two adults and nine immature, seen together on 

 Cherry Pond, suggested that they constituted a family reared 

 upon these waters ; on July i, a single bird of the tristis type 

 swam across Weed's Pond, while we stood on the bank, and 

 although later it rose on wing it did not leave but lit in again. 

 In September and October flocks varying in number from a 

 dozen to thirty birds are seen from time to time on Cherry or 

 lyittle Cherry Pond, or in flight in the vicinity. 



Most of those birds which have been seen on the ponds in 

 the summer, near enough to distinguish whether they were of 

 the type rubripes or rubripes tristis, have been of the latter type. 

 Perhaps only two have been distinctly seen which were of the 

 former type, namely, on July 30, 1908. These took wing so 

 near to us on our approach that the red legs were clearly seen. 



13. Nettion carolinense. Green -winged Teal. 



In Dr. Allen's " Birds of New Hampshire " Mr. Spaulding 

 is recorded as noting the occurrence of Green-winged Teal in 

 the Connecticut valley at lyancaster. 



14. Querquedula discors. Blue- winged Teal. 



A not uncommon fall migrant. In the last four seasons 

 several have been seen on Cherry and I^ittle Cherry Ponds in 

 late August and in September, the earliest record being that of 

 eight birds seen on August 31 and again on September 3 in
