8o MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB 



104 [233] Micropalama himantopus (Bonap.). 



Stilt Sandpiper ; '■ Bastard Yellow-leg." 



Irregular, and at times not uncommon transient visitor. July 22 to October 2. 



I have seen the Stilt Sandpiper at Clark's Pond. It is a diligent feeder on 

 mud-flats and probes the mud with bill slightly opened. Although its body is not 

 larger than that of a Ring-neck, its long legs make it look as big as a Dowitcher. 

 The legs are yellow, but not as bright as those of the Yellow-legs. Its bill is 

 long and slightly decurved. There is a light line through the eye. In flight it 

 shows a grayish-white tail but lacks the gray rump-triangle of the Dowitcher 

 and the white rump of the Yellow-leg. The note I have heard is a single whistle. 



105 [234] Tringa canutus Linn. 

 Knot; "Red-breasted Plover"; "Blue Plover"; 



Common transient visitor. May 20 to June 12 (June 25) ; July 17 to 

 November 8. 



On June 11 and 12, 1910, during an easterly storm I found four full-plumaged 

 Knots on the beach at Ipswich. In wading in a tidal pool one went beyond its 

 depth and swam across to the other side. 



While the tarsi of the young are greenish yellow, as stated in the original 

 Memoir, those of the adult are dark, almost black. 



106 [235] Arquatella maritima maritima (Briinn.). 

 Purple Sandpiper; "Rock Snipe"; "Winter Snipe." 

 Common winter visitor. (July 30) ; November i to May 30. 



On the late date of May 30, 1918, Mr. C. R. Lamb' found a flock of forty of 

 these birds on the Salvages off Rockport. He shot six for his collection. 



On March 14, 1909, at the Salvages and at Thatcher's Island, I saw three 

 flocks of Purple Sandpipers, one of ten, another of twenty-four, and a third of 

 twenty-eight individuals. In feeding at low tide among the rock-weed they are
