132 BIRDS OF THE HUMBER DISTRICT. 



I have found in the stomach of this species broken 

 fragments of freshwater shells, as well as entire minute 

 bivalve shells (Pisidia) . 



182. TRINGA SUBARQUATA (Giildenstaedt) . Curlew 

 Sandpiper. 



Not common. I have met with it on the flats in 

 the spring, but more commonly in the autumn, and 

 almost invariably associating with Dunlin, from which 

 in flight it may be distinguished by the white upper 

 tail- coverts. It is by no means a shy bird, and when 

 alone will permit a very near approach. One, a male, 

 was shot at Spurn on the 9th of October, 1869, from 

 a flock of Dunlin, by T. Buckley, Esq. 



183. TRINGA CANUTUS, Linnaeus. Knot. 



Occurs annually in the autumn, often in immense 

 flocks, on the Humber foreshores, some portion of 

 which, as the season advances, retire southward, many, 

 however, remaining; and they may be found in greater 

 or less numbers all through the winter along the 

 coast. These receive large accessions, probably from 

 some northern locality, in severe weather, their 

 abundance or scarcity during the winter season ap- 



square yards in extent) situated near the Aylesby "beck," 1 

 flushed four couple of u Jacks ;" at the same place, on the 5th 

 of April, three birds, and on the 25th a single bird. I again 

 carefully examined this place on the 2nd of May, but without 

 finding any.
