A MARKED ARCTIC TERN. 

 A YOUNG Arctic Tern {Sterna macrura) , bearing a ring stamped 

 " Vogelwarte Rossitten 2342," was picked up at Kellington, 

 near Pontefract, Yorkshire, on August 20th, 1911, and sent 

 to me by Major W. B. Arundel. 



Dr. H. Weigold informs me that he " ringed " this bird 

 when a nestling on the island of Svlt (Schleswig-Holstein), on 

 June 27th, 1911. "^ H.F.W. 



FIELDFARES SWALLOWING F.^CES OF 

 THEIR YOUNG. 

 During a recent visit to Nonvay, I had excellent opportunities 

 of studying a pair of Fieldfares [Turdus pilaris) at the nest, 

 and whilst in hiding for several hours, I repeatedly saw both 

 male and female swallow the fceces of their young. This 

 was usually accomphshed immediately after the process of 

 feeding, but several times the act of sw allo\^'ing was per- 

 formed during intervals between feeding the chicks, and 

 often when the bird still retained a considerable quantity of 

 food in the bill. 



On two occasions I observed the female swallow several 

 small pieces of dry grass, which she took from the bottom 

 of the nest, and which presumably had become fouled. 



The accompanying photograph, although not illustrating 

 the above-mentioned facts, will perhaps be of interest as, so 

 far as I am aware, nothing of a similar nature has previously 

 been pubhshed. Howard Bentham. 



ROCK-THRUSH IN SUSSEX. 

 On September 1st, 1911, a specimen of the Rock-Thrush 

 {Monticola saxatilis) was shot at Rett, Sussex. Another 

 was obtained on September 2nd at the same place. I examined 

 them in the flesh, and found the}^ were both young birds. 



Upon dissection, one proved to be a cock and the other a 

 hen. This is the first record for Sussex, and I believe the 

 first occasion this species has been obtained in the British 

 Isles on the autumn migration. H. W. Ford-Lindsay. 



[Saunders {Manual, p. 17) only admitted the authenticity 

 of one specimen, shot in Hertfordshire on May 19th, 1843 : 

 but more recently an adult male was caught at the Pentland 

 Skerries, Orkneys, on May 17th, 1910, and another seen there 

 on the same day {Ann. Scot. Nat. Hist., 1910, p. 148 ; 1911,
