76 BIRDS. 
retire south on the approach of winter. Immigrants on 
their way north occur on the coast in April and May, 
many in summer plumage. Has occasionally appeared far 
inland. 
305. Machetes pugnax (Z.). Ruff. 
Periodical visitant, in extremely limited numbers, observed 
chiefly in Holderness and on the Humber, especially about 
Paull, on their spring passage in May, and in autumn in 
August and September. A very rare straggler inland. 
Until about the commencement of the present century 
this species was abundant, and bred in the carrs of East 
Yorkshire, on Skipwith Common near Selby, and also on 
Hatfield Chase and the carrs about Doncaster, where Mr. 
Hugh Reid—as he informed Mr. More —remembered 
their breeding quite plentifully. Mr. Arthur Strickland 
informed Mr. Allis, in 1844, that before the drainage of the 
carrs they used to be taken in considerable numbers in the 
breeding season, but that he should doubt if any had bred 
in the county within the half-century. 
306. Calidris arenaria (Z.). Sanderling. 
Winter visitant, common on the coast, arriving in July and 
August, and leaving in May. Of shore birds this is the last 
to leave in spring and the first to arrive in autumn. Far 
inland it is rarely observed as a straggler. 
307. Tryngites rufescens (Vzei//.). Buff-breasted Sanc- 
piper. 
308. Bartramia longicauda (Sechst.). Bartram’s Sand- 
piper. 
309. Totanus hypoleucus (Z.). Common Sandpiper. 
Summer visitant, breeding in more or less abundance on the 
streams and reservoirs in the north-eastern, western, and 
west-central portions of the county, but not in the low- 
lands. Arrives in mid-April, leaving in August and 
September. In East Yorkshire it is observed during 
migration, but it is probable that they may breed on the 
streams about Driffeld, Mr. F. Boyes informing me that 
he has never failed to observe the birds there in the 
summer months.
