The Possibilities of Bird-Marking. 217 



The distinct evidence of considerable southward movement contained in 

 these records is of interest when compared with the evidence of stationary 

 habits obtained by marking large numbers of this species at the colony on 

 Borkum, at the south-eastern corner of the North Sea (Thienemann, Journal 

 'fiir Omithologie, 1910, p. 632). And we have ourselves a record of a Herring- 

 Gull (A. IT. 12140) marked as a young bird at Loch Aan Eilean, the Lewis, 

 Outer Hebrides, by Mr Andrew Harley, on 7th June 1910, and shot at 

 Stornoway (Lewis) at the beginning of December 1910, as reported by 

 Mr F. A. Lowe. 



A Black-headed Gull (Zarits ridibunchis : A.U. 13179), marked on 12th 

 July 1910, by Mr Lewis N. G. Eamsay, on the Sands of For vie, Aberdeenshire, 

 was killed near Bayon, Gironde, France, about 18th January 1911, as 

 reported by the Mayor of Bayon and by Mr T. Ludovic. Several unimportant 

 short-distance records have also been obtained for this species, including 

 records of three birds out of fifty marked in 1910 at a colony near York, by 

 Mr H. B. Davidson, and recorded in the autumn from Hull (2) and Newcastle 

 respectively. 



A Guillemot (Uria troth: A.U. 11230), one of a number of sea-fowl marked 

 as young birds on the Dunbuy Bock, Oruden Bay, Aberdeenshire, on 11th 

 July 1910, by Mr Lewis N. G. Eamsay and others, was shot on 29th November 

 1910, at Marstrand, a dozen miles north of Gothenburg, Sweden, as reported 

 by Dr Jagerskiold of Gothenburg Museum, where the bird is now preserved. 



This enumeration exhausts all the important records for non-passerine 

 birds that have come to hand up to date. Turning now to the Fasseres, 

 we find that they make up the majority of the birds we have marked, 

 but that they have afforded an extremely small proportion of "returns." 

 In fact, there are only two outstanding records. 1 



A Song-thrush (Turdus mitsicus : A.U. 14299), one of a brood of five 

 marked in the nest on 4th June 1910, at Skene House, Dunecht, Aberdeen- 

 shire, by Miss D. Hamilton, was shot on 6th November 1910 at Leiria, 

 Fortugal, " by a party of hunters." Several Portuguese newspapers containing 

 notice of the event were sent to me, and later I received the ring and full 

 details from Mr Buy Ferreira. This is, so far, the only long-distance record 

 that we have obtained in the case of a passerine bird. 1 



On 29th June 1909, an adult Swallow (Rirundo rustica) was caught, 

 ringed (A.U. 4498), and released, at Har warden Farm, Busthall, Kent, by Mr 

 Ernest C. B. Parsons. On 14th June 1910, it was recaught by Mr Parsons at 

 the same farm. It may be mentioned that a considerable number of similar
