220 BRITISH BIRDS. 



Arctic Tern {Sterna macrura). — " Country Life," No. 516, 

 marked by Mr. Riley Fortune on the Fame Islands on July 

 17th, 1909. Recovered (caught) at the Barns Ness Light- 

 house near Dunbar, Scotland, on August 23rd, 1909 (Country 

 Life, Oct. 16th, 1909, p. 543). 



Black-headed Gull (Larus ridibundus). — Vogelwarte 

 Rossitten, No. 1289, marked by Dr. J. Thienemann at Ros- 

 sitten, Germany, on July 16th, 1908, as a half-fledged 

 nestling. Recovered (shot) on Breydon Water, Norfolk, on 

 October 15th, 1909. 



Mr. A. H. Patterson has kindly sent me this bird, 

 which was in adult plumage. Dr. Thienemann, of the 

 Rossitten Bird Observatory, to whom I communicated the 

 occurrence, kindly gave me the above details of the ringing 

 of the bird, and informs me that this is the first Black-headed 

 Gull to be recovered in England. One of the routes laid 

 down by Dr. Thienemann for this species is along the west 

 (not east, as printed supra, p. 207) coast of France, but this 

 route is based apparently on only two recorded recoveries ! 



H. F. W. 



Wigeon (Mareca penelope). — Aberdeen University, No. 2052. 

 one of a brood of five marked at the head of Loch Brora, 

 Strath Brora, east Sutherlandshire Scotland, on June 19th, 

 1909, by Mr. F. Gunnis, of Gordonbush, Brora. Recovered 

 at Westpolder (information through Mr. H. J. Louwes of that 

 place), Ulrum, Province Groningen, north-eastern Holland, 

 on September 3rd, 1909. 



The bird had therefore borne the ring for two months and 

 a half, and had travelled about 500 miles in a south-easterly 

 direction. A Landsborough Thomson. 



MIGRATION IN THE MEDITERRANEAN. 



I was very interested to see Commander Lynes' conclusions as 

 to migration routes across the Mediterranean (supra, pp. 136-9). 

 This spring I happened to be passing down the Mediterranean 

 during a part of the migration season and took particular note 

 of all birds which I saw. The weather was very calm and 

 fine, and remarkably few birds were met with, but curiously 

 enough the one place where any number was seen was in 

 35° 10' N., 17° 40' E., or right in the middle of Commander 

 Lynes' sea-area IV. , where he tells us only odd stragglers are 

 met with during abnormal weather conditions. Turtle-Doves 

 were the only birds in any number, and every twenty 

 minutes or so, all the morning on April 25th, when in about
