later, one from co. Londonderry (five months), and 

 one from co. Mayo (three months). 



Southern, Ireland shows ten returns, viz., one from 

 CO. Dublin, four months later, three from co. Wicklow 

 seven, six, and one month later (all 1913 bred birds), 

 two from CO. Waterford, three and a quarter years, and 

 eight months later, one from co. Cork (four months), 

 two from CO. Limerick three and a half years and eight 

 months later, and one from co. Galway two months later. 



From Devon two returns came, one year and eight 

 months, and one year and five months later, but Dorset 

 shows five returns, nine, eight, three and two months 

 and three weeks after being marked, the last having 

 made great headway for so young a bird. Hampshire 

 returned two rings one year and eight months, and six 

 and a half months after marking. 



The ten birds recovered in France probably journeyed 

 by the west coast route, as none Mas recovered further 

 north than Cherbourg. It seems probable that they 

 travelled via the Channel Islands, since five returns 

 came from Brittany and one from Normandy. The 

 earliest return of the ten French recoveries was from 

 Cherbourg in Normandy only a month after being 

 marked as a nestling. Of those recovered in Brittany 

 three were six months after ringing, one six and a half 

 months, and the fifth one year and seven months. Three 

 recoveries were made in the centre of the Bay of Biscay 

 coast, two in Charente Inferieure, two years and ten 

 months and one year and seven months later, and the 

 tliird in Vendee five months later, and one in the south 

 of the Bay, in Gironde, seven months later. Six of 

 these French recoveries were 1912 birds, and five of 

 them were made Mdthin seven months of marking. 



One was recovered in Spain six months later in Vigo 

 Bay (also a 1912 bird), and two in Portugal near Oporto 

 eight months later, and near Lisbon two years and five 

 months later, the latter also being a 1912 bird.
