MIGBATION OF BIRDS IN N.E. LINCOLNSHIRE. 211 



Numenius arquata (Linn.). Curlew. — On the nights of July 

 22nd and 27th I heard the cries of Curlews passing over Grainsby, 

 apparently travelling from E. to W. A few appeared on the 

 coast on July 30th, but were less numerous than usual until 

 Oct. 8th, when some large flocks came in. 



iV. phcsopus (Linn.). Whimbrel. — Two or three on the coast 

 on July 30th. A large flock passed over Grainsby on the 

 morning of Aug. 10th. Last seen on the coast on Sept. 22nd. 



Sterna minuta, Linn. Little Tern. — A flock of six immature 

 birds of this species on the coast at Donna Nook on Sept. 22nd. 

 The Arctic Tern was very abundant about this time. 



Mergulus alle (Linn.). Little Auk. — A living example of this 

 species was found in a drain at the inland parish of North 

 Thoresby by a labourer, but it was dead when it reached me. 

 The weather in the North Sea had been extremely bad for some 

 days previous to its appearance. 



Podicipes fluviatilis (Tunstall). Little Grebe. — Two of these 

 little birds appeared on North Cotes sluice on Oct. 13th, one of 

 them being in perfect breeding plumage.
