190) records eight adults opposite his house at 

 Great Marlow on April 10, 1895. It has 

 also once occurred on the reservoir near Tring 

 in October 1886. 



187. Common Tern. Sterna fluvia tills, 



Naumann. 



The sea swallow, as it is generally called, 

 is a frequent visitor to all larger pieces of 

 water and streams throughout the county. 



1 8 8. Arctic Tern. Sterna macrura, Naumann. 

 According to Clark Kennedy this tern has 

 several times been observed and obtained in 

 the county : river Thames, Marsworth and 

 Wilstone reservoirs. 



189. Little Tern. Sterna minuta, Linn. 

 An irregular and somewhat rare summer 



visitor, appearing mostly in small flocks on 

 the Thames and larger reservoirs of the 

 county during the autumnal migration period 

 or in late summer. The terns are mostly 

 called ' sea swallows.' 



190. Black-headed or Brown-headed Gull. 



Larus ridibundus, Linn. 

 The commonest of all Lartdee, passing 

 through in small numbers during the migration 

 periods, and also seen sometimes in the late 

 summer as well as in winter on the Thames, 

 on reservoirs and streams. 



191. Common Gull. Larus canus, Linn. 

 Certainly less numerous than Larus ridi- 



bundus, being a sea bird which does not breed 

 inland, but is nevertheless often observed on the 

 larger inland waters of the county (Thames, 

 Chesham, Wycombe Rye, Halton reservoirs). 



192. Herring-Gull. Larus argentatus,Gmd\n. 

 This bird appears accidentally, mostly in 



severe weather, on the larger waters of the 

 county. 



193. Lesser Black-backed Gull. Larus fuscus, 



T 



Linn, 



An irregular visitor to the Tring reservoirs, 

 therefore doubtless occasionally occurring in 

 Buckinghamshire. 



194. Great Black-backed Gull. Larus mari- 



nus, Linn. 



Probably now and then occurring in 

 Buckinghamshire, as it has been identified on 

 the Tring reservoirs by W. Rothschild and 

 the keeper, when visiting pinioned specimens 

 of the same species. 



195. Kittiwake. Rissa tridactyla (Linn.). 

 On January n, 1830, a kittiwake was 



killed near Dinton Hall. According to 



Clark Kennedy, it occurs sometimes on the 

 Thames and has been shot near Chesham. 



196. Pomatorhine Skua. Stercorarius poma- 



torhinus (Temminck). 



The only records we know of are those 

 given in Clark Kennedy's book, viz. : ' I was 

 informed by Mr. Gardner, of Oxford Street, 

 that a skua of this species was sent to them 

 for preservation by a gentleman resident in 

 Buckinghamshire, on whose estate it was 

 procured. The precise date, or further par- 

 ticulars, I was unable to ascertain. A second 

 was taken some years since near Crendon ; 

 and Mr. Burgess told me of a third which 

 was shot at Chesham, in November or Decem- 

 ber, 1859. The last is in the collection of 

 Mr. Lowndes.' 



197. Guillemot. Uria troile (Linn.). 



According to Kennedy a male was caught 

 in the river at Fenny Stratford on November 

 13, 1852, and another was seen near Simpson, 

 in Buckinghamshire, on November 14, 1852. 



198. Little Auk. Mergulus alle (Linn.). 



We have two Buckinghamshire records. 

 A single specimen was taken in 1841 'on 

 one of the large pieces of water near Drayton 

 Beauchamp' (fide Rev. B. Burgess in Ken- 

 nedy, p. 212). Mr. Thos. Marshall (Stan- 

 dard, December 21, 1901) says that he knows 

 of one obtained in Bulstrode Park, Bucks. 



199. Puffin. Fratercula arctica (Linn.). 

 According to information from Mr. Heneage 



Cocks a puffin was caught after the great gale 

 in October 1881, near Aylesbury. 



200. Great Northern Diver. Colymbus gla- 



cialis, Linn. 



Occurring occasionally on the larger waters 

 of the county. An adult bird was found by 

 William Saunders of Ford on December 3, 

 1774 (Dinton Hall MS. and picture). A 

 ' young one ' (?) was obtained alive at Chequers 

 Court near Risborough on May 9, 1850. 

 Mr. W. B. Bolting (Field, xxvi. 426) records 

 having bought one in December 1865, which 

 was shot on the Thames ; and a Mr. Lamb 

 shot one at Maidenhead in 1794. It has 

 also occurred two or three times on the Tring 

 reservoirs.
