“ Red-back.” Abundant spring and autumn migrant. Have 
taken it late in November. I do not think it winters. 
On June 18, 1868, | saw and shot several specimens of 
this Sandpiper about the fresh-water ponds on Ipswich 
beach ; they were fat, and, upon dissecting, the females 
did not exhibit any signs of breeding ; they were evidently 
the young of the preceding year.

tumn by Mr. W. Brewster, at Rye Beach, New Hampshire.*
