VOL. vm] RINGING BLACK-HEADED GULLS. 211 



The following details of the returns of the Ravenglass 

 ringed birds will perhaps prove of interest. 



Western Side. 



Of those going due north on the west coast only three 

 birds reached north of the Clyde, viz., six months later 

 to Argyllshire, and two to Dumbarton three months 

 later. Others occurred in Lanark, Renfrew and Ayr, 

 and in the neighbouring counties of Dumfries and 

 Kirkcudbright within from one to seven months ; another, 

 one year three months later in Dumfries, and another, 

 eleven months later in the same county : the latter 

 being found close to two gulleries during the breeding- 

 season was possibly nesting there. 



Three birds at least were nesting at the Ravenglass 

 Guile ry where they were hatched, for they were found 

 dead there in the nesting-season, two of them two years 

 and the third three years later. Four other birds were 

 probably nesting in their parent gullery, for they were 

 found dead in the breeding-season only a few miles 

 away, three years, two years and two months, one year 

 and one month, and one year respectively after marking. 

 I might also say that I have seen, feeding their young, 

 several nesting birds at Ravenglass which bore rings, 

 but as I could not examine the numbers of these it is 

 impossible to say whether the birds were bred there or 

 not. Another bird was found dead in the nesting- 

 season two years later close to a gullery near Carlisle. 

 Eleven others were obtained within the parent-county 

 at periods var3rLng from one year three months to three 

 years and four months after being marked there as 

 nesthngs. 



In the neighbouring county of Westmorland one was 

 obtained one year five months later, and three others 

 within three months. 



The largest percentage of returns, 28.9, came from 

 Lancashire, and of these 27 per cent, were from the 

 Fumess district of north Lancashire, 46 per cent, from
