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 (L.). 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 (Vieill.). Buff-breasted Sand- 



piper. 



308. Bartramia longicauda (Bechst.}. Bartram's Sand- 



piper. 



309. Totanus hypoleucus (L.). 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 Driffield, Mr. F. Boyes informing me that 

 he has never failed to observe the birds there in the 

 summer months.
